WARNING

•

The engine exhaust, some of its constituents, and certain vehicle components contain or emit chemicals

known to the State of California to cause cancer, birth defects or other reproductive harm.

This unit is equipped with an internal combustion engine and should not be used on or near any unim-

proved forest-covered, brush-covered, or grass-covered land unless the engine’s exhaust system is

equipped with a spark arrester meeting applicable local or state laws (if any). If a spark arrester is used, it

should be maintained in effective working order by the operator.

•

In the State of California, the above is required by law (Section 4442 of the California Public Resources

Code). Other States may have similar laws. Federal laws apply to federal lands. A spark arrester muffler

may be available.

NOTE: The engine manufacturer is responsible for all engine-related issues with

regards to performance, power-rating, specifications, warranty and

SAFETY PRECAUTIONS

A. General

1. Read this Operator’s Manual before starting

the mower. Study the controls and learn the

proper sequence of operation.

2. Do not allow anyone to operate or maintain

this machine who has not read this manual.

Never permit children to operate this machine.

3. Never carry passengers.

4. Do not remove any shields, guards or safety

devices. If a shield, guard or safety device is

damaged or does not function, repair or

replace it before operating the mower.

5. Always wear safety glasses and safety shoes

when operating or maintaining this mower. Do

not wear loose-fitting clothing.

8. Do not operate machines on slopes when

traction is reduced (wet grass, ice, soft

ground, loose ground, leaves, pine needles,

debris, etc.).

9. Avoid turning downhill if possible, go slowly

and use extra care when turning downhill.

10. Do not operate machines during reduce visi-

bility (low light, fog, rain, etc.).

11. Do not operate machines with non-approved

attachments.

12. Do not operate machines that are dam-

aged.....have machine repaired.

13. Do not operate machines that have not been

properly maintained.

6. Disconnect the spark plug wires and remove

the key from the ignition to prevent the engine

from accidentally starting before performing

any maintenance on this mower.

7. Never run the engine indoors without ade-

quate ventilation. Exhaust fumes are deadly.

8. To avoid serious burns, do not touch the

engine, exhaust pipe or muffler while the

engine is running or until it has cooled after it

has been shut off.

14. Use only replacement parts that are the same

or equivalent to the original equipment.

15. Do not modify machines or any of their com-

ponents, especially the engine governor!

16. Do not operate machine for more than 2 hours

without hearing protection.

C. CAUTION

1. Use proper protective equipment when oper-

ating machine (gloves, boots, and hearing

protection are recommended).

2. Read entire machine Operator’s Manual.

3. Make sure operators are fully trained in the

safe use of the machine.

9. The liquid in the battery is dilute sulfuric acid.

Always wear safety glasses and rubber gloves

when working on the battery. Do not overfill

the battery.

4. Follow all safety instructions when using the

machine.

10. Lead-acid batteries generate hydrogen and

oxygen gases which form an explosive mix-

ture. Keep sparks and flames away at all

times.

terminals can produce sparks and heat...connections

to the terminals must be kept tight, and the terminals

and battery surfaces kept clean of acids and corro-

sion. If batteries are re-charged or “jumped” from

external sources, make sure that the connections are

made properly and in the correct sequence...connect

to the positive terminal of the good battery first, then

connect that to the positive terminal of the weak bat-

tery. The third connection should be to the negative

terminal of the good battery, followed by the negative

terminal of the weak battery. If sparks are observed

or heating of the wiring or connectors is detected,

disconnect in reverse order (I.E., the negative termi-

nal of the weak battery first). Batteries should be re-

charged at a constant voltage...generally 14.5 +/- 0.5

volts DC for a nominal 12 volt DC battery.

11. When looking for oil leaks, never run your

hand over hydraulic hoses, lines or fittings.

Never tighten or adjust hydraulic hoses, lines

or fittings while the system is under pressure.

If high-pressure oil penetrates the skin, the oil

must be removed within a few hours by a doc-

tor familiar with this form of injury or serious

complications may result.

B. Related to Fuel

1. Fuel is highly flammable and its vapors can

explode if ignited. Please respect it.

2. Do not smoke or permit others to smoke

while handling fuel.

3. Always use approved containers for fuel and

fill slowly to decrease the chance of static

electricity buildup and spillage.

4. Store fuel in well ventilated and unoccupied

buildings away from sparks and flames.

5. When dispensing gasoline into approved con-

tainers, place the container on the ground

when refueling to avoid a possible static elec-

tricity ignition of fuel vapors.

6. Do not fill containers while it is inside a vehi-

cle, trunk, the bed of a pickup or floor of a

trailer.

7. Always shut off the engine and permit it to

cool before removing the fuel tank cap.

8. Always fill the fuel tank outdoors.

9. If the fuel container spout will not fit inside the

fuel tank opening, use a funnel.

D. When Mowing

1. Keep adults, children and pets away from the

area to be mowed.

2. When operating this mower in the forward

direction, DO NOT allow the steering levers to

return to the neutral position on their own.

Always maintain a firm grip on the levers,

operate them smoothly and avoid any sudden

movements of the levers when starting or

stopping.

3. If the mower is equipped for side discharge,

never use the mower without the discharge

chute installed and placed in the down position.

4. Always remove debris and other objects from

the area to be mowed.(Note: debris and loose

grass will reduce traction.)

10. When filling the fuel tank, stop when the fuel

reaches one inch from the top. This space is

5. Mow only in daylight.

6. Watch for holes, sprinkler heads and other

hidden hazards.

necessary for tank expansion. Do not overfill

11. Wipe up any spilled fuel.

7. Avoid driving too close to trees, creeks,

ditches, sand traps and other obstacles.

8. Before backing up, check behind you and

watch where you’re going.

9. Always reduce speed when making a turn,

and when grass is wet.

C. Related to Batteries

Batteries are stored electrical energy devices that

may be serviceable with removable caps (the electro-

lyte levels can be checked), or may be non-service-

able (no attempt should be made to open the vents).

10. Always mow across slopes, never up and

down the slope. Do not operate on steep

slopes and slow down before turning.

11. Be careful when crossing gravel paths or

roadways. Always turn off the blade clutch

switch and wait until the blades stop rotating

and raise the cutting deck to the transport

position. Always allow other vehicles to have

the right-of-way.

12. If you hit a solid object while mowing, turn off

the blade clutch switch, place the left and right

steering levers in the neutral position, move

the throttle to slow, set the parking brake, shut

off the engine and take the key from the igni-

tion switch. Inspect for damage. Repair any

Batteries may contain lead (Pb) and sulfuric acid,

and they must be re-cycled and not disposed of nor

abandoned. Sulfuric acid can cause severe burns,

and in the event of contact, the areas should be

flushed with water and a physician contacted. Bat-

tery cases should not be punctured. Lead is poison-

ous and is contained within the positive and negative

terminals as well as within the battery’s internal grid-

work of plates and active materials.

Explosive gases are generated when batteries are

re-charged, so sparks, flames and heat sources

should be avoided. Loose connections at the battery

damage. Make sure the blades are in good

condition and that the blade bolts are tight

before restarting the engine.

DANGER:

Damaged ROPS and OPDs must be replaced prior

to operator use!

13. Never leave the mower unattended without:

turning off the blade clutch switch; placing the

left and right steering levers in the neutral

position; moving the throttle to slow; setting

the parking brake; shutting off the engine and

taking the key from the ignition switch.

14. Never walk or stand on the discharge side of a

mower with the engine running. Turn off the

blade clutch switch if another person

approaches while you are operating the

mower.

15. Never attempt to operate the traction unit

without the mowing deck attached.

3. Seat belts shall be used and shall be prop-

erly fastened about the operator’s waist at all

times, except when the ROPS or OPDs are:

- not properly installed and/or not properly

secured onto the machine

- damaged in such manner that their struc-

tural integrity has been compromised

- not in their fully upright and locked position

4. Seat belts are attached to the movable por-

tion of the seat when suspension seats are

utilized, and therefore the seat-mounting

base must be secured to its pivot means and

the pivot means latched to the frame of the

machine. Seat belts are attached to the seat

or the frame of the machine when non-sus-

pension (standard) seats are provided, how-

ever, if a suspension kit is added to a seat,

the seat belt must be attached to the mov-

able portion of the seat or suspension mech-

anism, the seat-mounting base must be

secured to its pivot means, and the pivot

means be latched to the frame of the

16. Keep the mower and especially the engine

and hydraulic components clean and free of

grease, grass and leaves to reduce the

chance of fire and to permit proper cooling.

E. Towing

1. Tow only with a machine that has an approved

hitch designed for towing. Do not attach towed

equipment except at the hitch point.

2. Follow the manufacturers recommendation for

weight limits for towed equipment and towing

on slopes.

machine.

3. Never allow children or others in or on towed

equipment.

4. On slopes, the weight of the towed equipment

may cause loss of traction and loss of control.

Note: 5 degrees (9%) maximum slope.

5. Travel slowly and allow extra distance to stop.

DANGER:

If ROPS and OPDs are folded down or missing,

seat belts shall not be fastened. Worn or damaged

seat belt assemblies must be replaced prior to

operator use.

5. Brush Guards and canopies can afford addi-

tional protection for the operator. The Brush

Guard can deflect tree limbs, clothes lines,

and other obstacles that otherwise could

come in contact with the ROPS and OPDs.

Contact of ROPS and OPDs by items such

as tree limbs, clothes lines, guy wires, and

buildings, could create hazardous conditions

whereby the machine could experience a tip-

over or roll-over. The canopy can provide

protection for the operator from some envi-

ronmental exposure (sunlight, rain, etc.).

Work lights may be available.

6. The ROPS and seat belt are integral parts of

this machine and should not be tampered

with, modified in any manner, or removed.

7. The ROPS extends above and behind the

operator position, and therefore the operator

must be aware of potential contact of the

ROPS with items such as trees, buildings,

doorways, clothes lines, utility wires, etc., that

could cause the machine to upset or roll-

F. Operator Protection System -Foldable

1. This machine is equipped with an Operator

Protective System (OPS), which includes:

a. A Roll Over Protective Structure (ROPS) or

Operator Protective Device (OPD) which

may be of the fixed or folding configuration

b. Seat belt assembly with retractable function

2. ROPS and OPDs are structures designed to

provide a crush-resistant space for the oper-

ator when properly seat-belted within the

designated seating area of the machine in

the event of a machine tip-over or roll-over.

Folding ROPS and OPDs shall be used in

their fully upright and locked configurations

except in those circumstances whereby they

need to be momentarily folded-down to avoid

contact with items such as tree limbs, clothes

lines, guy wires, buildings, etc. At other times

and conditions, ROPS and OPDs shall be in

their fully upright and locked configurations.

over....use caution in (or avoid) areas where

the ROPS could come in contact with any

structures, trees, etc.

ing bearings are utilized throughout the sus-

pension mechanism that provides an

additional 2” of suspension travel.

8. The ROPS and seat belt add additional mass

that elevates the machine’s Center of Gravity

(C.G.) which negatively affects the machine’s

stability and traction....use extra caution when

operating on slopes.

9. Inspect the ROPS and seat belt assemblies

on a regular basis for damage and improper

operation....replace all components that are

damaged or are not functioning properly with

authorized replacement parts.

10. Failure to use the seatbelt properly could

result in serious injury or death if an acciden-

tal overturn occurs. In order for the ROPS to

be effective, the seat belt must be securely

fastened around the operator at all times

when the operator is on the machine. Contact

with the ROPS during an overturn could

cause serious injury or death.

4. A retractable seat belt assembly with inertia-

lock is attached to the “ride” portion of the

seat frame. The seat frame is attached to the

mechanical suspension, which is attached to

the roller tracks that are bolted to the seat

base in one of the three (3) locations - the

seat assembly can be detached and re-

installed 1” forward or 1” aft from the factory

installed position. When the two (2) hairpin

clips are removed from the frame-mounted

stud-bolts, the complete seat assembly and

seat base can be pivoted forward onto the

foot platform - this provides access to the

battery, hydraulic reservoir and filter, as well

as some of the electrical system and control

linkages. The seat base must be secured

with the hairpin clips prior to machine opera-

tion.

11. The ROPS will not prevent the machine from

upsets or roll overs.

12. Only approved attachments should be used

on this machine.

Note: The seat base must be secured by

properly installing the hairpin clips into both

frame-mounted stud-botls, otherwise, the seat

assembly could tilt forward. The Operator

Presence Sensor must be connected to the

G. Suspension Seat

electrical wiring harness.

1. This unit is equipped with an adjustable sus-

pension seat system, which includes a fold-

forward seat with retractable seat belt

assembly, a low profile mechanical suspen-

sion, and an Operator Presence Sensor

(OPS).

2. The seat bottom is covered with a heavy-

duty vinyl fabric and integrates the EVC

cushion comfort system that provides up to 1

3/8” dampered (for shock isolation) suspen-

sion travel. An OPS in the form of a switch, is

integrated into the seat bottom and is con-

nected to the machine electrical system. The

seat back is also covered with a heavy-duty

vinyl fabric, it adjusts to recline up to 16

degrees, and it will fold forward for transport

or protection from the elements of weather

(lever actuated on operator’s left side). The

armrests are adjustable for operator comfort

(knob inside armrests actuated from the bot-

tom). Roller bearing single-locking tracks

provide easy repositioning fore/aft up to 5”

m. Never leave the mower unattended without

observing the following: turn off the blade

clutch switch, placing the steering levers in

the neutral position, moving the throttle to

slow, setting the parking brake, shutting off

the engine and taking the key from the igni-

tion switch.

n. Never walk or stand on the discharge side

of the mower when the engine is running.

Turn off the blade clutch switch if another

person approaches while you are operat-

ing the mower.

A.General

1. When Mowing:

a. Keep adults, children, and pets away from

the area to be mowed.

b. When operating this mower, in the forward

direction, do not allow the steering levers

to return to Neutral on their own. Always

maintain a firm grip on the levers, operate

them smoothly and avoid any sudden

movements of the levers when starting and

stopping.

c. If the mower is equipped for side dis-

charge, never use the mower without the

discharge chute installed and placed in the

down position.

d. Always remove debris and other objects

from the area to be mowed (Note: debris

and loose grass will reduce traction).

e. Mow only in daylight.

f. Watch for holes, sprinkler heads, and other

hidden hazards.

g. Avoid driving too close to trees, creeks,

ditches, sand traps, and other obstacles.

h. Before backing up, check behind and

watch where you are going.

i. Always reduce speed when making a turn,

and when grass is wet.

j. Always mow across slopes, never up and

down the slope. Do not operate on steep

slopes and slow down before turning.

Avoid turning downhill if possible, start at

the bottom and work up to the top. Use

extra care and go slowly when turning

downhill. Control the speed and direction

of the zero turn machine “primarily” with

the speed/directional control (lap bar) of

the downhill side of the machine...I.E.,

maintain the uphill side lap bar “essen-

tially” in a fixed position.

o. Never attempt to operate the traction unit

without having the mowing deck attached.

p. Keep the mower and especially the engine

and hydraulic components clean and free

of grease, grass, and leaves to reduce the

chance of fire and permit proper cooling.

b. If on an hillside, start at the bottom so that the

turns are uphill rather than downhill.

c. Align the mower so as to head directly toward

the object on the far side.

Note: If low traction conditions occur, follow

these procedures for “zero turns”:

To turn clockwise (front of machine moves toward RIGHT)

when traveling FORWARD:

d. Slowly increase the speed of the machine to

match cutting conditions, terrain, and operator

familiarity with the controls and keep the

machine headed directly toward the alignment

object. Do not go fast as to reduce cut quality

or to be uncomfortable in controlling the speed

and direction of the machine.

e. When approaching the other end of a strip,

slow down or stop before turning. A U-turn is

recommended unless a zero turn is required.

The speed of a U-turn that will allow for

machine controllability and minimal turf

defacement will be dependent on several fac-

tors including: the speed of the turn, the radius

of the turn, the tire tread pattern, the traction

coefficient of the tire to the traction surface,

the slope of the traction surface.

f. Remember, a zero turn requires that the for-

ward or reverse travel of the machine be

stopped prior to the initiation of the turn or

severe turf defacement can occur.

g. To prevent rutting or grooving of the turf,

change the direction that the strips are mowed

by approximately 45 degrees the next and

each subsequent time that the area is mowed.

1. Come to a stop,

2. Then slowly move both lap bars rearward (no more

than 1/2 maximum reverse speed) to initiate REVERSE

travel,

3. Then slowly move the LEFT lap bar forward while

maintaining the RIGHT lap bar in the rearward travel

position.

4. To stop the turn and reintiate FORWARD travel,

slowly move the RIGHT lap bar from the REVERSE

travel position to a FORWARD travel position equal t that

of the LEFT lap bar.

5. Alternatively, release both lap bars and the machine

should stop turning, (this is a safety check, the normal

procedure is for the operator to slowly bring the lap bars

to the Neutral psoition).

To turn counter-clockwise (front of machine moves toward

LEFT) when traveling FORWARD:

1. Come to a stop,

2. Then slowly move both lap bars rearward (no more

than 1/2 maximum reverse speed) to initiate REVERSE

travel,

3. Then slowly move the RIGHT lap bar forward while

maintaining the LEFT lap bar in the rearward travel posi-

tion.

4. To stop the turn and reintiate FORWARD travel,

slowly move the LEFT lap bar from the REVERSE travel

position to a FORWARD travel position equal t that of the

RIGHT lap bar.

5. Alternatively, release both lap bars and the machine

should stop turning, (this is a safety check, the normal

procedure is for the operator to slowly bring the lap bars

to the Neutral psoition).

B.Controls

1. Engine ignition and start switch: (See Figure

1.) Located on the instrument housing below the

right side of the operator’s seat. When the key

is inserted and turned clockwise, 45 degrees,

the ignition circuit is closed. When the engine is

“cold”, have the switch in the “on” position until

the glow-plug light goes out. Turning the switch

further against spring pressure starts the

engine. The engine will only start if the blade

clutch switch is in the “off” position, the parking

brake is engaged and the left and right steering

levers are in the neutral position. The key should

always be removed from the switch if the opera-

tor leaves the mower’s seat.

b. Avoid turning downhill if possible, if not use

extra care and go slowly.

c. Avoid turning when going downhill, traction is

at a minimum going downhill.

d. Do not operate with discharge side of the

mower toward streets, buildings, playgrounds,

parking lots, other machines, animals, and

other people.

e. Avoid operation or use extreme care if the

traction surface is wet, unstable, or slippery.

f. Use extra care when grass clippings, leaves,

pine needles, or debris are present as traction

can be reduced.

g. Slow-down before turning and come to a com-

plete stop before any zero turn maneuver.

h. Do not stop machine or park machine over

combustible materials such as dry grass,

leaves, debris, etc.

3. To Mow Grass and Produce a Striped Pattern

a. Pick a point on the opposite side of the area to

be mowed (post, tree, shrub, etc.).

2. Glow Plugs: (See Figure 1) Combustion cham-

ber plugs are fitted with the necessary precise tip

protrusion into each combustion chamber, to

enable the sprayed fuel to be properly ignited

during cranking, without causing a significant

drop of combustion efficiency during engine run-

ning. Glow plugs, due to their high tip tempera-

ture when activated, give satisfactory starting at

ambient temperature-bottom limits approaching

that of other starting-fluid aids.

tion. Power to the electric clutch will also be cut

off if the operator leaves the operator’s seat.

6. Parking Brake: (See Figure 2.) Located on the

left side of the traction unit. The handle is an

overcenter lever which applies the drum-type

brake on each drive wheel when the handle is

pulled to the rear. The brake must be engaged in

order to start the engine.

Steering Levers

7. Foot Pedal Lift: (See Figure 3.) Located on the

right front corner of the mowing deck. A two pedal

mechanism is provided whereby one pedal (first)

is used to raise, to momentarily hold the imple-

ment at a desired height (if needed), and to latch

it in the transport or maximum height setting. A

second pedal is used to unlatch the mechanism

from the transport or maximum height setting, to

lower, or to momentarily hold the implement at a

desired height. The pedals can also be used in

conjunction with each other when the upper por-

tion of a foot activates the first pedal to raise the

implement, and the lower portion of the foot

(heel) activates the second pedal to release the

latch. This provides a hands-free operation with

the exception of when an implement height

change is required. For changing implement

height, at least one hand is required to reposition

the pins to provide 1/4” height-of-cut increments.

Foot Pedal Lift

the rear to the front will increase the engine

speed from slow to fast.

4. Left and Right Steering Levers: (See Figure 3.)

These hinged levers open out to the side in any

position to permit the operator to be seated or to

leave the mower’s seat. The operator, when

seated, can pull the levers up to the operating

position, a comfortable forearm’s length away.

These levers control all of the movements of the

mower. Pushing both levers forward causes the

mower to move forward. Pulling both levers back

causes the mower to move backward. Pushing

one lever ahead of the other lever causes the

traction wheel on the side where the lever is

ahead to rotate faster than the other traction

wheel, making the mower turn toward the side

where the lever is behind. When one lever is

pushed forward and the other lever pulled back

the same amount, one traction wheel will turn in

reverse and the mower will turn within its own

length.

The mechanism includes: An adjustable location

foot pedal that is used to raise the implement

and/or latch it in the transport position, that is

directly connected to the implement lift linkage;

adjustable force counter-balance springs to

reduce the effective weight of the implement and

thereby reducing the forces needed on the first

and second pedals for activation - tighten both

springs equally to reduce the force at the foot

pedal; a second pedal pivotally attached to the

first pedal that releases the mechanism from the

latched configuration; a height adjustment link

and index provide predetermined height for the

implement - it is settable in 1/4” increments; a

lock position for the height adjustment link setta-

ble by the pin in the highest (also transport posi-

tion) or lowest (also for mower deck removal and

installation).

In order to start the engine, both steering levers

must be in the neutral position; the parking brake

must be engaged; and the blade clutch switch

must be “off”. However, once the engine starts,

the parking brake must be released before the

operator places the steering levers into the

operating position or the engine will

automatically shut off.

Note: The Steering Lever will return toward

neutral when released, but they should be placed

in neutral by the driver. If the Drive Handles are

not placed in neutral, the tractor may creep.

The following features are incorporated into the

foot pedal implement lift design: Foot actuated

implement lift with one pedal (1st) for lift and

latch, with a second pedal for release and lower;

allows for some operators with physical limita-

tions to use the implement lift mechanisms and

the machine; reduces potential for operator

fatigue; accommodates a variety of operator

sizes, shapes, and strengths; does not require

the use of hands (with the exception of resetting

the implement height) during normal machine

5. Electric Blade Clutch Switch: (See Figure 1.)

Located on the right side of the mower beside the

ignition switch. This is an “on/off” push pull switch

that controls the electric blade clutch which sup-

plies power to the cutting blades through the

PTO. The switch must be turned off to start the

engine and should be turned off for safety any

time another person approaches the mower or

the mowing deck is raised to the transport posi-

left or right side of the mower). When the

fuel reaches one inch from the top of the

tank, stop. DO NOT OVERFILL. Space must

be left for expansion. (see page 29 for more

specs.)

Note: The 19hp

and 23hp use the 5

gallon fuel tank.

b. Engine Oil: (Filled at the factory before

shipment.) Pull out the oil dipstick, wipe it off

and reinsert it. Pull it out again and read the

oil level. If it is below the operating range,

add oil through the fill tube using a funnel to

bring it up to the top of the operating range.

operation - thusly the hands can be used for

other functions

c. Engine Coolant: Use Shell Dex-cool,

extended life anti-freeze diluted with water

to create a 50:50 mixture. Maintain the fluid

level in the expansion overflow tank at the

prescribed level indicated on the tank.

d. Hydraulic Oil: (Filled at the factory before

shipment.) The hydraulic oil tank is located

beneath the operator’s seat. Always wipe off

the area around the oil tank fill neck before

checking the oil level to prevent dirt from

contaminating the oil. Remove the cap and

make sure the oil level is 1/4” below the oil

tank fill neck. If the oil level is low, fill with

Shell Rimula 15w40 or equivalent oil. Equiv-

alent oil should meet GM Allison C-4.

e. Tires: 10-12 psi Rear, 20-25 psi Front

Caster Tires

8. Fuel Shutoff Valve: (See Figure 4.) Located

behind the operator’s seat, the valve has three

(3) positions: “off”, “Left Tank”, “Right Tank”.

Close this valve if you are not going to run the

mower for a period of 30 minutes or more to

prevent flooding the engine. The fuel system

operates under pressure when the engine is

running.

Note: In the left tank position, fuel will be

drawn from the left tank only, and excess fuel

not consumed by the engine will be returned to

the left tank. This also applies to the right tank.

9. Seat Adjustment Lever: The Seat Adjustment

Lever is located beneath the seat. The Seat

Adjustment Lever is used to move the seat for-

ward and backward. To place the seat in the

desired position pull the seat adjustment lever

to the left then push the seat forward or back to

the desired position. Release the lever so the

seat will lock in place. The lever on the side

allows a choice of four seat back angles, plus a

folded-down position. Knobs in each armresr

allow them to be adjusted to the desired height.

10. Hourmeter (Digital Tachometer Optional):

(See Figure 1 on page 10) Located on the right

side of the mower in front of the ignition switch.

When the machine is running the tachometer

displays engine rpm. When the machine is off

the tachometer displays running time.

Note:New tires are overinflated in order to

properly seat the bead to the rim. The normal

working pressure for the traction tires is 10-12

psi. The front caster wheels should be inflated

to 20-25 psi.

2. Check that all Nuts, Bolts and Screws are

Tight.

3. Check the tension of the deck drive belts.

a. Remove the deck cover

b. The tension of the deck drive belts are

maintained by a spring mechanism that

adjusts for wear and stretch.

c. Examine the belts for cuts, fraying, and

excessive wear. Replace if any of these are

detected.

11. Warning Lights: (See Figure 1) Indicator

lights are provided to notify when conditions of

“Low oil pressure”, “High temperature coolant”,

“Low alternator output”, and “Glo-plug activa-

tion” are present. A buzzer is activated with the

“High temperature coolant” light.

d. Replace the deck cover.

4. Adjust the Mowing Deck: The cutting height

is set anywhere in the range of 1-1/2" to 5". You

may need to adjust the mowing deck to achieve

the proper angle for mowing. Follow the proce-

dures below to set the appropriate angle to the

mowing deck.

C.Initial Adjustments

a. Park the mower on a flat paved surface,

engage the parking brake, shut off the

engine, remove the key from the ignition

switch, remove connection of the spark

plugs and using the second foot pedal,

1. Check the fluid levels and tires:

Note:These checks should be made daily,

before starting the engine.

a. Fuel: Using a good grade of #2 Diesel fuel,

tion.

5. Lubricate all fittings listed in the mainte-

nance section.

b. Using a ruler, pencil and paper, measure and

note the distance from the paved surface to

the bottom edge of the mowing blade at the

front and the back of the deck on each side of

the mower. (Four dimensions.)

D. Zero Turn Break-In And Operating Pro-

cedures

DANGER:

Reread the “When Mowing” Safety Precautions.

Note:The front edge of the mowing deck

should be 1/8"-1/4" below the rear edge of the

deck so that the blades are cutting grass in only

the front half of their circular path. This

decreases friction and reduces the drive power

required.

The following procedures are suggested for operators

of ride-on machines which have zero turn capabilities.

1. Orientation:

a. Read the entire Operator’s Manual.

b. Sit on the machine, adjust the seat before-

and-after, then adjust the speed/directional

(lap bar) controls (they can be adjusted fore

& aft, as well as up & down — 9/16" wrench

required).

c. Become familiar with all of the machine con-

trols, instrumentation, safety and instruction

signs, and safety devices.

d. Move (or have moved) the machine to a safe,

level area with no obstructions including

objects, pedestrians, and animals.

2. Initial Operation:

c. If the dimension at the front of the mowing

deck is 1/8"-1/4" lower than the dimension at

the rear of the deck on each side of the

mower, do not adjust. If not, you will need to

adjust the Deck Lift Spring Assist (See Figure

5). You may also need to adjust the Deck

Links (See Figure 5).

Deck Lift Spring inner nut

a. Use protective equipment for eyes, hands,

hearing, feet, legs, head and other areas of

the body if needed — safety eye glasses,

gloves, earplugs, boots, hats, etc.

WARNING:

Hearing Protection is required for all operator

exposure exceeding two (2) hours.

Deck Links

Figure. 5

d. Lower the mower deck to the cutting position.

With a wrench loosen the inner rear nut on

the Deck Lift Spring Assist. To adjust the

deck up or down, use a wrench and with a

few turns, adjust clockwise or counter clock-

wise the outer rear nut of the Deck Lift Spring

Assist. Repeat this procedure on the oppo-

site side of the Mower. Once the deck is

adjusted, retighten bolts.

e. With the deck still in the cutting position,

adjust the Deck Links. With a wrench loosen

the top inner bolt of the Deck Link. To adjust

the side of the deck up or down turn the top

bolt clockwise or counter clockwise a few

turns. Adjust both front and rear Deck links as

necessary. Retighten nuts.

b. Ensure that the area is free of animals and

bystanders, especially children!

c. Survey the area where the equipment is to be

used to make sure it is free of debris, sticks,

stones, wires, bones, and other foreign

objects which could cause injury to bystand-

ers, damage to the machine, or damage to

nearby facilities. Also make sure that the area

is free of toys, stakes, pipes, chain, cable,

potholes, drop-offs, and step slopes.

d. Inspect the machine to make sure:

1. All guards, shields (including mower chute

deflector) are in their proper place, are

secure, and are functional.

2. That there are no spilled or leaking fuel or

oil sources, nor loose fuel or hydraulic tank

caps, hoses or fittings.

3. That there are no loose or missing hard-

ware nor any missing items.

f. Raise the mowing deck to the transport posi-

tion using the upper foot pedal.

g. Use the second foot pedal to lower the mow-

ing deck to the cutting position and repeat

step “b.” above to make sure that the desired

cutting height has been attained. If the

dimensions are not correct, repeat steps “c.”

through “f.” above.

4. That no non-approved devices are

installed.

5. That all safety signs and decals are prop-

erly installed and legible.

e. This is a one person machine, operator only!

Riders are not permitted under any circum-

stance!

f. To start the engine on the machine:

1. Make sure the park brake is set to the “ON”

position, both lap bars are in the neutral/

start position, and the Power Take Off (PTO

also referred to as blade control switch) is in

the “off” (down) position.

2. Move the engine speed control (throttle) for-

ward (half way).

3. Insert the key in the ignition and start

switch, turn the switch to “On”, and wait for

the glo-plug light to go out.

opposite from the side that was advanced

— I.E. to turn clockwise (to the Right), move

the LEFT lap bar forward more than the

right side, and to turn counter-clockwise (to

the LEFT), move the RIGHT lap bar forward

more than the left side. NOTE: If one lap bar

is in the neutral position and the other is

advanced, the turn side tire will not rotate

and a “pivot turn” will be executed — turf

defacement could occur (if on grass) as well

as potential damages to the traction surface

and the tire. If the lap bar on the turn side is

not brought all the way to neutral, then the

turn side tire will continue to rotate and a “U-

turn” will be executed with a low potential for

turf defacement as well as traction surface

and tire damage.

4. Turn the ignition key in a clockwise direction

to the “Start” position until the engine starts.

Note: The cooling system fan incorporates a

i. To drive in the REVERSE direction:

1. Make sure no bystanders, animals, or

objects are behind the machine. Look

behind the machine, and use extreme care.

2. Slowly, move both lap bars toward the rear

of the machine until the machine begins to

move rearward. Release the lap bars and

the machine should stop. The more the lap

bars are moved toward the rear of the

machine, the faster the machine will move in

the reverse direction. Release the lap bars

and the machine should stop traveling in

reverse (this is a safety check, the normal

procedure is for the operator to slowly bring

the lap bars to the neutral position).

60 second delay for starting. Then it will begin a

cycle of 1 minute down-flow followed by 10

minute up-flow.

g. Check safety devices:

1. With the park brake engaged, try to move

one of the lap bars (speed/directional con-

trol) from the neutral/start position — the lap

bars should not move with the park brake

engaged.

2. Repeat this procedure with the opposite

side lap bars.

3. With the park brake engaged and the lap

bars in the neutral/start position, advance

the engine speed control completely forward

(Hi-idle), engage the PTO control switch

(pull upward), then lift off the seat — the

engine should stop running. Sit down and

the engine should run. Turn off the PTO by

pushing the control switch down.

h. To drive in the FORWARD direction:

1. Set the engine speed to 2000 to 2500 rpm

(refer to tachometer on right control panel).

This must be increased to full speed (3525-

3675 rpm) after becoming familiar with the

machine.

3. Do not retard the lap bars rapidly as this

could cause turf defacement and/or loss of

traction.

4. To turn, retard one lap bar ahead of the

other and the machine will turn toward the

same side that was retarded — I.E., to turn

counter-clockwise (to the LEFT), move the

LEFT lap bar rearward more than the right

side, and to turn clockwise (to the RIGHT),

move the RIGHT lap bar rearward more

than the left side. NOTE: If one lap bar is in

the neutral position and the other is

2. Release the park brake.

3. Slowly, move both lap bars toward the front

of the machine until the machine begins to

move forward — release the lap bars and

the machine should stop moving. The more

that the lap bars are moved toward the front

of the machine, the faster the machine will

move in the forward direction. Release the

lap bars and the machine should stop travel-

ing forward. (This is a safety check, the nor-

mal procedure is for the operator to slowly

bring the lap bars to the neutral position).

4. Do not advance the lap bars rapidly as this

could cause turf defacement, loss of trac-

tion, and/or instability.

retarded, the turn side tire will not rotate and

a “pivot turn” will be executed. Turf deface-

ment could occur (if on grass) as well as

potential damages to the traction surface

and the tire. If the lap bar on the turn side is

not brought all the way to neutral, then the

turn side tire will continue to rotate and a “U-

turn” will be executed with a low potential for

turf defacement as well as traction surface

and tire damage.

j. To perform a “zero turn”:

1. Please note, a zero turn maneuver can not

be executed while the machine is moving in

the Forward or, Reverse directions, the

machine must come to a stop first.

5. To turn, advance one lap bar ahead of the

other and the machine will turn toward the

Download from Www.Somanuals.com. All Manuals Search And Download.

2. To turn clockwise, slowly move the LEFT lap

bar forward while simultaneously moving the

RIGHT lap bar rearward. Release both lap

bars and the machine should stop turning.

3. To turn counter-clockwise, slowly move the

RIGHT lap bar forward while simultaneously

moving the LEFT lap bar rearward. Release

both lap bars and the machine should stop

turning (this is a safety check, the normal

procedure is for the operator to slowly bring

the lap bars to the neutral position).

g. To go forward, move both steering levers

slightly forward and the mower will slowly

move forward. The farther you move the levers

forward the faster the mower will go forward.

h. To back up, move both steering levers slightly

backward and the mower will slowly move

backward. The farther you move the levers

backward the faster the mower will go back-

ward.

i. To turn, pull the lever back on the side to

which you want to turn. The farther back you

pull the lever, the faster and more sharply you

will turn. Initially, you will have to be careful to

avoid turning to fast and too far.

3. Start the Engine:

a. Open the fuel shutoff valve by selecting the

left or right tank position.

b. Sit on the Seat. Set the parking brake “On”.

c. Make sure that the left and right steering

levers are in their neutral position.

d. Turn the electric blade clutch switch “Off”.

e. Push the throttle control to a position a third of

the way between slow and fast.

f. Insert the key in the ignition and start switch,

turn the switch to “On”, and wait for the glo-

plug light to go out.

g. Turn the ignition key in a clockwise direction to

the “Start” position until the engine starts.

j. After you have mastered operating the mower,

use the second foot pedal to lower the mowing

deck to the cutting position and pull on the

electric blade clutch switch to start the blades

rotating.

k. Practice mowing in straight passes. When you

feel confident, slowly practice mowing around

obstacles such as trees.

5. Parking the Mower:

a. Push off the electric blade clutch switch.

b. Use the upper foot pedal to raise the mowing

deck to the transport position.

c. Drive the mower to the cleanup or storage

area.

d. Move the throttle to slow.

e. Place the steering levers in the neutral posi-

tion.

Note:Do not hold the key in the “Start” posi-

tion for more than 10 seconds or you may damage

the starter. If the engine does not start in this

time, wait about 30 seconds and try again.

4. Operating the Mower: Operating a zero-turning-

radius mower is not like operating a tractor-type

riding mower. The zero-turning-radius mower is

much more maneuverable and much less fatigu-

ing to operate. However, getting used to the fin-

gertip control of the zero-turning-radius mower

takes some practice. We strongly recommend

that you locate a “test area” where you can oper-

ate the mower for about 30 minutes without being

disturbed.

f. Set the parking brake.

g. Turn off the ignition switch and take the key

from the switch.

h. Close the fuel shutoff valves.

E.Mower Cutting Blades

The blades normally “factory installed” on a mower

afford the best grass cutting performance on the majority

of grasses and mowing conditions; however, there will

be occasions whereby the grass type, stage of grass

growth, soil conditions, and weather conditions will

require different cutting blade types. Since the mower

decks are designed so that over-lap of the cutting blades

generally exceed 1.5”, there is no need for orientation of

one cutting blade to an adjacent blade (I.E., the blades

do not need to be “timed” nor synchronized).

a. Get into the operator’s seat.

b. Start the engine.

c. Use the transport lever to raise the mowing

deck to the transport position. Make sure the

blade clutch switch is off.

d. After the engine has warmed, adjust the throt-

tle to the fast position.

e. Release the parking brake.

f. Fold in the steering levers to the operating

position.

Hi-lift- These are generally the best cutting blades for

most grasses and mowing conditions. These blades will

provide extra “lift” for the thinner leaf grasses, will handle

lush grasses, and will provide maximum grass and

debris discharge. These blades are generally required

for material collection systems. More horsepower is

WARNING:

When operating this mower forward, do not allow

the steering levers to return to the neutral posi-

tion on their own. Always maintain a firm grip on

the steering levers, operate them smoothly and

avoid any sudden movements of the levers when

starting or stopping.

be unlatched, pivoted upward, and secured via a prop-

rod for access to the engine, etc.

Medium-lift- These blades require less horsepower

than the hi-lift, and they generally work well in wider leaf

grasses and some mulch applications.

MAINTENANCE AND

SERVICE

Low-lift- These blades require less horsepower than hi-

lift and medium-lift blades, and they generally work best

with wide leaf grasses, sparse grass growth, and sandy

soil conditions. They generally produce the lowest noise

levels. Bahia blades are configured without offset, and

with a maximum amount of sharpened cutting edge.

WARNING:

Disconnect the spark plug wires or remove the

key from the ignition to prevent the engine from

accidentally starting before performing any main-

tenance on this mower.

Mulch- These blades are generally designed for use in

cutting decks equipped with mulch baffles. The shape of

the blade generally produces higher turbulence in order

that the grass can be repeatedly cut and re-cut into

smaller pieces. These blades generally require more

horsepower than other blades. Mulch blades work best

when the grasses are cut at the highest levels, minimal

lengths of grasses are removed, and grass conditions

are generally dry.

A. Mower Deck

1. Removing the Mower Deck:

a. Apply the parking brake. Remove ignition key

and both spark plug caps.

b. Lower the cutter deck to the ground. Capture

the foot pedal by placing the height of cut cle-

vis pin in the “lock” position.

c. Remove tension of the PTO belt by moving

the belt tensioning rod.

F.Cooling System

This product is equipped with a cooling system

employing state-of-the-art technology. A 12VDC pow-

ered fan draws air “upward” through a high efficiency

multi-pass heat exchanger for about 10 minutes, then

stops, runs in the “downward” direction for about 1

minute. Except for engine starting when the fan does not

run for the first minute, the fan blows downward (to clear

debris on the inlet screen) for about 1 minute, then

upward for about 10 minutes...this 1 and 10 minute cycle

repeats until the engine is shut off. The heat exchanger

is mounted at an angle so that the heat will be blown

away from the operator station. The heat exchanger can

Note:There is a certain amount of spring ten-

sion due to the weight of the deck. When remov-

ing the lift linkage from the deck the tension of the

springs will go from the deck to the lift handle.

Not capturing the lift handle while removing the

lift linkage from the deck will cause it to snap

back.

d. Detach the mower drive belt.

e. Remove six linchpins (See Fig. 6) (4) from the

deck and (2) from the front of the mower.

WARNING:

Never mow with dull blades! Blades that are

bent should be replaced! The cutting blades are

sharp and can cause severe injury. Wrap the

cutting surface of the blade with a rag to avoid

injury.

B.Hydraulic Oil

WARNING:

3. Sharpening a Blade.

a. Set the parking brake.

Never overfill the hydraulic units. Damage can

occur if the oil level is not within the proper oper-

ating range.

b. Clean any debris from the blades. Keep

blades sharp and free of build up at all times.

a. Sharpen blades evenly at the original 30°

angle to maintain balanced cutting blades.

Do not sharpen the underside of the blades.

Use a electric blade sharpener, a conven-

tional electric grinder or a hand file to

sharpen the blades.

Note:When adding hydraulic oil, do so in

small quantities and recheck the oil level before

adding more. It is important that you do not

overfill the reservoir to allow for fluid expansion.

ervoir for faster drainage. Remove nut caps

Read General Safety Precautions Nos. 9 and 10.

1. Battery: The battery is located beneath the

operator’s seat. Remove the fillcaps and check

the level of the liquid electrolyte in the battery

every 50 operating hours. If the level in any of

the six cells has dropped below the bottom of

the split ring inside the fill hole, refill the cell with

distilled water. To keep the outside of the bat-

tery clean, brush on a strong solution of bicar-

bonate of soda and water and rinse with clean

water. Keep the contacts and cable ends clean

with a wire brush and make sure the connec-

tions are tight. Coat the terminals with petro-

leum jelly to prevent corrosion.

2. Battery Storage: When storing the Mower for

long periods of time the following guidelines

should be taken.

a. Disconnect the battery cables from the ter-

minals and remove the battery. You will have

to remove the control panel to access the

battery strap. Replace control panel.

b. Clean the battery before storing. A dirty bat-

tery will lose its charge over time.

7. Safety Switches: There are three safety

switches in the electrical circuit which control the

engine. They are (1) the blade clutch switch, (2)

the steering lever/parking brake switch, (3) the

seat switch.They operate so that in order to start

the engine, the blade clutch switch must be off,

the parking brake must be engaged, and both

steering levers must be in the neutral position.

Once the engine is started, the seat must be

occupied and the parking brake must be

released before either of the steering levers can

be moved. Also, the seat must be occupied

before the blade clutch switch can cause the

blades to rotate.

ing operational checks should be made daily.

a. Blade Clutch Switch: Sit in the operator’s

seat. With both steering levers in the neutral

position and the parking brake engaged, turn

the blade clutch switch “on” and try to start

the engine. The engine should not start. If it

does, the blade clutch switch must be

replaced. If the engine does not start, turn

the blade clutch switch “off” and start the

engine. Now turn the blade clutch switch “on”

and the blades should rotate. If the blades do

not turn, the blade clutch switch must be

replaced, the seat switch must be replaced or

the electric PTO clutch must be repaired.

a. Remove the Negative (black) cable.

b. Remove the Positive (red) cable.

c. Release the hold down straps.

d. Remove the battery without tipping.

4. Installing the Battery

The air-gap should be checked every 100

hrs. (or less, if severe operating conditions

exist such as when there are many on/off

cycles, mulching operations, material collec-

tion systems used, and dusty/dirty condi-

tions), and the air-gap adjusted if more than

0.025". To inspect, remove the “negative”

cable from the battery and all sparkplug

wires. The air-gap should be checked with

feeler gages in the three slots of the BBC

(PTO Clutch). See page 24 for air gap adjust-

ment specs. There are three inspection slots

in the brake cover. To adjust, successively

tighten each of the three gap adjustment nuts

an equal amount. Insert a feeler gage (see

page 24 for specs) into each slot as the air

gap adjustment nut are tightened. The cor-

rect adjustment occurs when slight contact

with the feeler gage occurs. Engage the BBC

(PTO Clutch) a couple of times, and re-check

the air-gap. If it is not between the specs

listed on page 24, repeat the adjustment pro-

cedure.

Note:The battery is delivered from the factory

fully charged and filled with electrolyte.

a. Attach the Positive (red) cable.

b. Attach the Negative (black) cable.

c. Attach the rubber battery strap.

5. Jump Starting

Warning:

Failure to use this starting procedure can cause

sparking, and the gases in the battery to

explode.

a. Attach the end of the red jumper cable to the

Positive terminal (+) of the charged battery.

b. Attach the other end of the red jumper cable

to the Positive terminal (+) of the low charge

battery.

c. Attach the end of the black jumper cable to

the Negative terminal of the charged battery.

d. Attach the other end of the black jumper

cable to the frame of the unit with the low

charge battery.

b. Steering lever/Parking Brake Switch: Sit in

the operator’s seat. With both steering levers

in the neutral position and the blade clutch

switch “off”, release the parking brake and try

6. Fuses: There are two fuses located in the wiring

between the ignition and start switch and other

electrical components. This is a standard plug-in

to start the engine. The engine should not

start. If it does, the parking brake switch

must be repositioned or perhaps replaced.

If the engine does not start, engage the

parking brake and start the engine.

(see tire side wall for proper inflation pres-

sure).

b. Keep the valve caps tightened to prevent

air pressure loss.

2. Leaking Tires: When a flat tire occurs, repair

or replace immediately. The normal procedure

is to remove the wheel and replace it with a

spare. Take the leaking tire to a maintenance

area and repair. If a tire is getting soft, park

the mower on the nearest level, paved area. If

the leaking tire is on a traction wheel, put

blocks on each side of the opposite traction

wheel and jack up the tire that leaks about an

inch off the ground. Loosen and remove the

lug nuts and remove the wheel. Mount a

spare wheel and tire, replace the lug nuts, and

using a torque wrench, tighten them to 60

10 lb-ft.

c. Seat Switch: With both steering levers in

the neutral position, the parking brake

engaged and the blade clutch switch in the

“off” position, start the engine. Now

release the parking brake, hold down on

the back of the operator’s seat against

spring pressure. Release the operator’s

seat and the engine should stop. If the

engine does not stop, the seat switch must

be replaced. With both steering levers in

the neutral position, the parking brake

engaged and the blade clutch switch in the

“off” position, sit in the operator’s seat and

start the engine. Turn the blade clutch

switch to the “on” position and the blades

should start to rotate. Raise up slightly off

the operator’s seat and the blades should

stop. If the blades do not stop when you

dismount from the operator’s seat, the seat

switch must be replaced.

If the leaking tire is on a front caster wheel,

block both traction wheels and raise the

caster wheel so that the tire is an inch off the

ground. Loosen and remove the locknut from

the axle assembly and pull the axle assembly

from the caster yoke. The wheel and two

spacer sleeves will drop free. Slip the axle

assembly through one side of the caster

yoke, through a spacer sleeve, a spare

wheel, the other spacer sleeve and finally

through the other side of the caster yoke.

Then tighten the locknut on the end of the

axle assembly.

d. Electric PTO Clutch: This clutch operates

when the engine is running, the operator is

in the operator’s seat and the blade clutch

switch is turned on.This electric clutch is a

fairly trouble free device. If a problem

develops and the blades do not turn, first

check the 20 amp fuse and then investi-

gate the wiring harness and the connec-

tions to the seat switch, the blade clutch

switch and the electric blade clutch. Then

check out the seat switch, the blade clutch

switch and finally the electric blade clutch.

Lower the mower off the jack and continue

mowing. The wheel with the leaking tire

should be taken to the maintenance area, the

tire inflated to 20 psi and the wheel placed in

a large bucket of water. Carefully inspect the

tire, rim and valve for escaping air bubbles

which indicate a leak. Mark each leak with a

yellow marking crayon and then deflate the

tire to 8 psi and repeat the inspection. If the

leaks you find are pin hole size to 1/16"

diameter, the tire can be repaired using an

aerosol can of tire inflater and latex sealer

available from any auto supply store. Follow

the directions on the can. If the leaks are

larger than 1/16" diameter, the tire can be

repaired with rubber plugs also available in a

kit from any auto supply store. If the tire bead

is damaged, a tube will have to be installed in

the tire or the tire will have to be replaced.

D.Tires

The two front wheels are caster wheels that are free

to swivel to accommodate the direction of the Mower.

The two rear wheels are used to propel the Mower in

the direction of input from the drive handles. Inflation

pressure of the rear tires is important for stability

while the Mower is in operation. If the tire diameter is

not equal between the two tires, the Mower will pull to

one side.

1. Inflation Pressure:

a. Traction Tires—20 psi max; 10-12 psi rec-

3. Creeping: Creeping is the slight forward or

backward movement of the mower when the

throttle is on and the lapbars are in the neutral

position. If your mower creeps, refer to Steer-

ing Lever Adjustment Section F4, page 23.

reverse by pushing, you must release the

dynamic braking. Locate the valves on the pump.

Turn valves counter-clockwise (using a standard

7/16” wrench) one quarter turn to push the unit.

After pushing the mower to the desired location,

return both valves to the operating position by

turning the valve clockwise, but do not over-

tighten(See photo below).

To drain the hydraulic oil tank, place a 2 gallon drain pan

under the drain plug on the bottom of the hydraulic oil

tank. Remove the drain plug, drain the tank, then

replace the plug. Remove the three screws from the top

of the oil filter and take out the oil filter element. You

don’t have to drain the rest of the hydraulic system. Put

the replacement filter element in the oil filter and

lubricate the sealing surface. Install the three screws in

the top of the oil filter to secure the oil filter element.

(See photo below)

Hydro Release Valve

When the mower is parked with the engine running and

the steering levers in the neutral position, the parking

brakes should be applied. The parking brakes are drum-

type brakes mounted on each traction wheel.They are

both engaged by the same operating lever.

cap and the area around it before removing the

cap to prevent dirt from contaminating the oil.

Remove the fill cap and fill the tank with Shell Rimula

15W40 oil until the oil level is a 1/4” below the oil tank fill

neck. Leave this air space for expansion. Start the

engine and let it run at idle for about five minutes. Check

the filter for leaks. Idling the engine and the pumps in

this way will purge any air from the system. Shut off the

engine and recheck the oil level in the tank. Top-off if

necessary until the oil level is a 1/4” below the oil tank fill

neck.

Note:To increase parking brake capacity,

adjust brake cables at the brake arms equally.

Adjust the cable housing nuts one full turn and

check parking capacity. Repeat if parking brake

does not hold.

2. Repair: The mower is equipped with drum

brakes and will not normally require mainte-

nance. If they are not working properly, please

contact your service center.

Note:After unit is up to operating tempera-

ture, turn off engine and re-check hydraulic oil. If

oil appears foamy or contains excessive air bub-

bles, DO NOT OPERATE UNIT. Contact service

technician.

F. Hydraulic System

WARNING:

Never overfill the hydraulic units. Damage can

occur if the oil level is not within the proper oper-

ating range.

3. Hydrostatic Pumps and Motors: The pumps

are the hardest-working components in the

hydraulic system. They are in operation all the

time the engine is running. Because of

Note: When adding hydraulic oil, do so in

extremely close tolerances, wear is an important

factor in their life. Contaminants in the hydraulic

oil and cavitation does the greatest harm to the

pumps. Cavitation is a blockage in the supply

lines that produces a partial vacuum causing

small quantities and recheck the oil level before

adding more. It is important that you do not over-

fill the reservoir to allow for fluid expansion.

1. Hoses: Check the hoses from the hydraulic oil

tank to the oil filter to the hydraulic lines daily for

leaks or abrasion and replace any damaged

violent bubbling in the hydraulic oil in the

pump.

whenever the lap bars are in their Neutral

positions.

Check the two suction hoses (the hoses con-

nected to the filter) daily before starting the

engine. Look for a flattened condition or any

leaks and repair or replace as necessary. A

flattened or leakng suction hose will permit

cavitation to develop which can destroy the

pumps in a short time.

Note: Both lap bars must be in their Neutral

positions for the Park brake interlock mecha-

nism to function so as to prevent lap bar

movement (movement that would activate the

hydrostatic pumps producing Forward or

Reverse travel rotation of the wheel motors)

and to allow the Park Brake switch to be acti-

vated.

Contaminants or foreign matter in the oil will

also damage the pumps . To prevent this, use

a filter that captures particles as small as 25

microns or 25 millionths of a meter in diame-

ter. You can help in the battle against dirt by

being very careful when you remove or repair

a component in the hydraulic system. Thor-

oughly clean off any component before you

work on it. Plug the ends of any hose or line

you remove with a rubber or plastic plug. Use

plastic caps to seal off the ends of hydraulic

fittings. Place any component you remove in a

clean plastic bag so it can’t pick up dust or

dirt. Clean your hands frequently when work-

ing on the hydraulic components.

Whenever the Park Brake is applied (I.E., the

Park brake lever moved completely rearward

in the control panel slot), the lap bars should

be secured in their Neutral positions by the

linkage rods moving into the holes in the lap

bars. This lap bar Neutral lock mechanism

also activates the Park brake switch, which

allows for the engine to be started. If the lap

bars are in their Neutral positions, and they

are not “locked” so as to prevent movement

when the Park brake is applied, then the link-

age from the RTN on the hydrostatic pumps

and the lap bars must be adjusted. This is

done by determining which side (or both) rod

is not aligned to the hole in the lap bar, then

locating that side linkage rod turn-buckle at

the hydrostatic pump RTN, loosening the jam

nuts and lengthening or shortening the link-

age rod so that the rod snaps into the hole in

the lap bar.

Note:The pumps are not owner-repairable.

If a pump fails, contact your Cub Cadet Com-

mercial dealer. Do not disassemble the pump.

4. Steering Lever Adjustments: The steering

lever controls on this Zero Turn Mower (ZTM)

incorporate a patented interlock mechanism

that secures them in their Neutral position

whenever the Park Brake lever is applied.

Additionally, the lap bars can be opened in

any position - Neutral, when traveling For-

ward, when traveling in Reverse, or when exe-

cuting a zero-turn maneuvar. The lap bars

also incorporate a Return-To-Neutral (RTN)

feature with hydraulic dampers to provide

smooth, non-jerkey, control motion while

affording an automatic hydrostatic braking

means.

Dampers are incorporated into the lap bar

linkage to provide smooth, non-jerkey, control

action. The damper rate can be adjusted by

relocating the damper - lower to reduce the

damper action, and elevate to increase.

Note: The engine should be able to be

started whenever the Park Brake is applied,

and the lap bars are locked in their Neutral

positions - if not, the switch may need to be

adjusted or replaced.

Whenever the ZTM is on level ground with the

engine running and the lap bars in their Neu-

tral positions, the ZTM should not creep (I.E.,

move in the Forward or Reverse directions of

travel). If this occurs, contact your Service

representative for the procedure to reset the

RTN mechanism on the hydrostatic pumps. If

the hydrostatic pump RTN is adjusted, the

control linkage must also be readjusted.

Whenever the Park Brake lever is moved rear-

ward to the Park Brake engaged position, a

cable mechanism, connected to each drum

brake on the hydrostatic wheel motors,

applies force to each brake lever so that each

wheel brake mechanism can prevent brake

drum and wheel rotation. At the same time, a

second cable and linkage mechanism is acti-

vated to secure both lap bars in their Neutral

positions and to activate the Park Brake

switch. Both lap bars must be in their Neutral

positions for the neutral lock linkage to func-

tion - the spring-loaded linkage will force rods

in through aligning holes in each lap bar

d. Push the mower outdoors and start the

engine. Let the engine idle until it has

warmed up completely (4 to 5 minutes).

G.Cooling System

1. The cooling system should be inspected on a

regular basis for restrictions to air flow

through the heat exchanger core, and for

leaks.

2. The heat exchanger core should be cleaned

by moderate (50 psi) pressure air or water, but

not by brushing.

3. The collant is a 50:50 mixture of de-ionized

water and Shell Dex-cool ELA. The total vol-

ume is approximately 6.5 quarts. The coolant

should be replaced each operating season (or

750 hours).

4. Make sure the coolant level is correct “cold” in

the reservoir/overflow bottle.

H. Storage

1. General: If your mower will not be in service

for a few months, it should be stored in a dry

location that is not subject to drastic changes

in temperature. Before storing, the following

maintenance procedures should be per-

formed.

a. Clean the mower. The entire tractor and

cutting deck should be washed and

cleaned.

b. Sharpen the blades so that the mower will

be ready to use when needed.

C. Deck Corner Ball Wheel Roller Settings

1. Matching the set heights of the ball rollers on

the four corners of the mower deck to the

desired cut height will prevent edge scalping

and minimize any side-to-side variance in cut

height.

2. There are three height adjustment holes in

the bracket that mount the ball rollers to the

deck.

Note:If lap bar adjustments are required,

height adjustments should be made prior to

angular adjustments.

4. To adjust the height of the lap bars,

a. Remove the nuts from the lap bar mounting

bolts (see Fig. 11).

b. Remove the bolts and lap bar and repostion

to the seconc set of holes in the mounting

block.

a. Use the top set of holes for cut heights of 2

inches or lower.

c. Replace the bolts and nuts and tighten to

28-34 lb-ft.

b. Use the middle set of holes for a 2-1/2 - 3-1/2

inch cut height.

c. Use the bottom set of holes for cut heights of

4 inches or higher.

1. If angular adjustments are also required,

nuts can be tightened until snug at this

point.

d. The same adjustments should be made to

both sides of the mower.

D. Deck Center Anti-Scalp Roller Settings

1. The front and rear rollers help prevent the

scalping of high spots and uneven terrain

across the center section of the deck.

2. The rollers on the front of the deck are fixed at

the factory and can not be adjusted.

3. The rollers on the rear of the deck can be

adjusted downward one inch.

5. To adjust the front-to-rear angle of the lap bars,

a. Loosen the nuts on the lap bar mounting

bolts, leaving the bottom one fairly snug.

b. The top hole is slotted, allowing the lap bar

to pivot on the bottom bolt.

c. Move lap bar to the desired angle and

tighten the nuts to 28-34 lb-ft.

a. Lowering the roller will increase the strip-

ing effect left behind the mower.

b. This positioning of the rear roller will also

help to filter the mulched grass clippings

into the turf.

Note:In the neutral position, the handles of

the lap bars should be aligned with approxi-

mately a one inch gap between the tips. Adjus-

the gap by adding shim washers to the top

mounting bolt between the lap bar and the

mounting block.

c. Roller should not be lowered if the cut

height is set at 2-1/2 inches or lower.

d. Check the results of any adjustments to

the conditions described in section a,

above. Repeat any adjustment procedures

as required until all conditions are met.

E. Lap Bar Adjustment

1. Proper lap bar and seat adjustment will result

in the following:

a. In the neutral position with hands on the

lap bars,

1. Operator’s upper arms should be relaxed

and approximately vertical.

2. Operator’s forearms should be approxi-

mately vertical.

b. In the full forward position,

1. Operator’s back should stay in contact

with the seat back.

Lap Bar Mounting

Bolt and Nuts

2. Lap bars should not contact operator’s

legs.

c. In the full reverse position,

1. Lap bars should not contact the opera-

tor’s legs or torso.

2. Set the seat to the preferred operating position.

a. Adjustment lever is located under the front

edge of the seat.

mower centerline. The blade-to-ground height at

the rear of the blade tip should be 1/8" to 1/4” higher

than the front tip. This is referred to as blade pitch.

The sam height difference should be true for the left

blade, measured front and back.

F. Deck leveling Procedure

1. Park the mower on a flat paved surface, engage the

parking brake, shut off the engine, remove the key

from the ignition switch, disconnect the spark plug

wires and using the second foot pedal, lower the

mowing deck into the 4" height of cut position. (The

4" height of cut position is recommended in order

for one to see and obtain a measurement. Any

height of cut position is acceptable as long as a

proper measurement can be taken.)

2. Check the right and left front tire pressure. Adjust as

necessary to 20-25 psi. Tire pressure can affect

blade height by as much as a 1/4”.

3. Check the right and left rear Drive tire pressure.

Adjust as necessary to 10-12 psi.

8. To adjust the blade pitch the deck pitch must be

adjusted. Loosen the inner jam nuts at the rear of

the horizontal threaded rods. Start at Point C to

raise the rear of the deck, tighten the rear outer jam

nut to raise the deck pitch. Adjust the rear jam nut at

Point D to take the “slack out of the threaded rod.

9. The final adjustment would be to take the “slack”

out of the left rear linkage (Point D) by adjusting the

jam nuts on the eyebolt. Loosen the jam nuts and

tighten the upper nut to remove “slack”.

10. In many cases it will be necessary to adjust deck

height using both eyebolt adjustments and pitch

adjustment to achieve the correct blade-to-ground

heights. If you remember that the front right blade

tip adjustment is fixed and you level to that height,

adjusting the decks will be simplified.

11. Once the deck is level one may find that the height

of cut does not match the height of cut indicator. A

final adjustment may be made by lowering or rais-

ing the height of cut link accordingly. To raise the

deck: remove the shoulder bolt mounting the height

of cut link to the lift handle and reassemble the

shoulder bolt in the lowest of the three holes. To

lower the deck: remove the shoulder bolts mounting

the height of cut link, flip the height of cut link

around and reassemble the shoulder bolts in the

top of the set of three holes and the bottom hole.

(see Fig. 12)

4. Measure blade-to-ground height at the front tip of

the right blade. To obtain an accurate measure,

align blades in parallel with mower centerline, (i.e.

front to back).

5. Measure blade-to-ground height at the front tip of

the left blade. Be sure to measure at the blade tip

with the blades arranged in proper position.

6. To level the deck, adjust the eyebolt at the left front

of the deck (Point B) so that the blade-to-ground

height at the right front blade tip matches that of the

left front blade tip. This is done by loosening the jam

nuts on the eyebolt and tightening the upper nut to

raise the deck and loosening the nut to lower the

deck. The right front blade tip height is fixed so you

must adjust the left front tip to match it.

7. Measure the blade-to-ground height at the right rear

blade tip. Again be sure to measure at the blade tip

at the rear of the right blade when aligned along the

pump is included within the main fuel filter for use

in the event of first time start-up when fuel is

depleted from the system. The primer should be

pumped by hand until all air is purged (view

return line in fuel tank).

Fuel & Lube Specifications

A.Fuel Specifications

Use good quality fuel to get the correct power and per-

formance from the engine. The recommended fuel spec-

ification for Caterpillar engines is shown below.

3. The Main Fuel Filter is a spin-on cartridge that

should be changed every 500 hours of use (or

sooner depending on fuel quality and operating

conditions). This fuel filter is attached to a

mechanical hand primer. The primer must be

used to purge the fuel system of air.

Cetane number 45 minimum

Viscosity

Density

2.0/4.5 centistrokes at 40 C (104 F)

85% at 350 C (662 F)

4. The Fuel Valve provides a means to switch from

the “left” to “right” tank or “off” positions.

Cetane number: Cetane number indicates ignition per-

formance. Fuel with a low cetane number can cause

cold start problems and affect combustion.

C.Lubricating Oil Specifications

Use only good quality lubricating oil, such as shell Rim-

ula 15W40 which meets Caterpillar ECF-I and either of

the following:

Viscosity: Viscosity is the resistance to flow and if this

is outside limits, engine performance can be affected.

Density: Low density will reduce engine power, higher

density will increase engine power and exhaust smoke.

• API-CH-4 plus

• ACEA E5

Sulphur: High sulphur content (not normally found in

Europe, North America or Australasia) can cause engine

wear. if only high sulphur fuels are available, it will be

necessary to use a highly alkaline lubricating oil in the

engine or reduce the lubricating oil change interval.

Note: API CI-4 plus and ACEA ES oils that have not

met the requirements of Caterpillar’s ECF-I specification

may cause reduced engine life.

Caution: Always ensure that the correct viscosity grade

of lubricating oil is used for the ambient temperature

range in which the engine will run as shown in the chart

below.

Distillation: This is an indication of the mixture of differ-

ent hydrocarbons in the fuel. A high ratio of light weight

hydrocarbons can affect the combustion characteristics.

Recommended SAE viscosity grades

Low temperature fuels: Special winter fuels may be

available for engine operation at temperatures below

0 C (32 F). These fuels limit the formation of wax in the

fuel oil at low temperatures. If wax forms in the fuel oil,

this could stop the flow of fuel oil through the filter.

5W20

10W30

15W40

20W50

Aviation kerosene and R.M.E. type fuels: These fuels

may be used, but can effect the engine performance and

starting ability. The only aviation fuels that are permitted

for use with these engines are: JP5, Jet A and JP8 pro-

viding that 5% spindle oil is added, Aviation fuel JP4 is

not recommended. For more information on aviation

fuels refer to the Caterpillar application department.

Only up to 5% R.M.E. in mineral oil diesel fuel is permit-

ted. Biodiesel blends of up to 5% B100 and #2 diesel

fuel (B5) are allowed.

Electrical shut-off solenoid (ESOS): The ESOS is fit-

ted to the right hand side of the cylinder block, at the

rear of the fuel injection pump. When the solenoid is de-

energised, a control rod pushes the fuel control rack to

the ‘no fuel position’ in the injection pump. The unit oper-

ates from a 12V supply in an ‘energise to run’ condition,

an electrical failure will give automatic fuel shut-off.

Ensure the lubricating oil sump is filled slowly after warm

up, check with the dipstick that the oil level is correct.

Change the oil and filter in accordance with the service

instruction.
