PROTECTION FOR CHILDREN
PROTECTION AGAINST TIPOVERS
Tragic accidents can occur if the operator is not alert to
the presence of children. Children are often attracted to
the machine and the mowing activity. Children who have
been given rides in the past may suddenly appear in the
mowing area for another ride and be run over or backed
over by the machine. Never assume that children will
remain where you last saw them.
(Continued From Previous Column)
5. STAY ALERT for holes and other hidden hazards. Tall grass
can hide obstacles. Keep away from ditches, washouts, cul-
verts, fences and protruding objects.
6. KEEP A SAFE DISTANCE (at least 3 feet) away from edge of
ditches and other drop offs. The machine could turn over if
an edge caves in.

2. DO NOT allow children in yard when machine is operated
(even with the blade OFF).
8. Use weights or a weighted load carrier in accordance with
instructions supplied with a grass catcher. DO NOT operate
machine on slopes exceeding 10 degrees (18% grade) when
equipped with grass catcher.

4. DO NOT allow pre-teenage children to operate machine.
5. ALLOW only responsible adults & teenagers with mature
judgment under close adult supervision to operate machine.
6. DO NOT operate blades in reverse. STOP BLADES. LOOK
and SEE behind and down for children, pets and hazards
before and while backing.
10. DO NOT operate machine on wet grass. Reduced traction
could cause sliding.
11. Chose a low enough speed setting so that you will not have
to stop or shift on a slope. Tires may lose traction on slopes
even though the brakes are functioning properly.
12. DO NOT operate machine under any condition where trac-
tion, steering or stability is doubtful.
7. USE EXTRA CARE when approaching blind corners, shrubs,
trees, or other objects that may obscure vision.
13. Always keep the machine in gear when going down slopes.
DO NOT shift to neutral (or actuate hydro roll release) and
coast downhill.
PROTECTION AGAINST TIPOVERS
Slopes are a major factor related to loss-of-control and
tip-over accidents, which can result in severe injury or
death. All slopes require extra CAUTION. If you cannot
back up the slope or if you feel uneasy on the slope, DO
NOT mow it. Use extra care with grass catchers or other
attachments; these affect the handling and the stability of
the machine.

3. Data indicates that operators age 60 and above, are involved
in a large percentage of mower-related injuries. These opera-
tors should evaluate their ability to operate the mower safely
enough to protect themselves and others from serious injury.
1. DO NOT operate machine on slopes exceeding 15 degrees
(27% grade).
2. Exercise EXTREME CAUTION on slopes above 10 degrees
(18% grade). Turn blades OFF when traveling uphill. Use a
slow speed and avoid sudden or sharp turns.

Features & Controls
CONTROL FUNCTIONS
The information below briefly describes the function of individual controls. Starting, stopping, driving, and mowing
require the combined use of several controls applied in specific sequences. To learn what combination and sequence
of controls to use for various tasks see the OPERATION section.
Motion Control Levers
Engine Speed Control
These levers control the ground speed and direction of
the rider. The left lever controls the left rear drive wheel
and the right controls the right rear drive wheel.
The engine speed control controls engine speed. Move
the engine speed control forward to increase engine
speed and back to decrease engine speed. Always
operate at FULL engine speed.
Moving a lever forward increases the FORWARD speed
of the associated wheel, and pulling back on a lever
increases the REVERSE speed.
Choke
The further a lever is moved away from the neutral posi-
tion the faster the drive wheel will turn.
Close the choke for cold starting. Open the choke once
the engine starts. A warm engine may not require chok-
ing. Move the lever forward to close the choke. Move the
lever back to open the choke.
See the OPERATION section for steering instructions.

Mower Cutting Height Adjustment Lever
The mower cutting height is adjustable from 1-1/2” to 4”, in
1/2” increments. See CUTTING HEIGHT ADJUSTMENT
for adjustment information.
OFF
RUN
Stops the engine and shuts off the
electrical system.
Allows the engine to run and powers the
electrical system.
Parking Brake
START
Cranks the engine for starting.
The parking brake is incorporated into the left motion con-
trol lever. Locking the lever into the neutral locked position
engages the parking brake; moving the lever out from the
neutral locked position disengages the brake.
NOTE: Never leave the ignition switch in the RUN posi-
tion with the engine stopped–this drains the battery.
Hour Meter
The hour meter measures the number of hours the key
has been in the RUN position.
Note: Both motion control levers must be locked into the
neutral lock position together, or the unit will stall.
Note: The hour meter will register the passage of time
when the engine is running. The hour meter has a self
contained power source so the total hours are always
visible.
PTO Switch
IMPORTANT
The figures and illustrations in this manual are
provided for reference only and may differ
from your specific model. Contact your dealer
if you have questions.
The PTO (Power Take-Off) switch engages and disen-
gages the mower blade clutch. To engage the PTO, pull
UP on the switch. Push DOWN to disengage. Note that
the operator must be seated firmly in the rider seat for
the PTO to function.
Transmission Release Valves
The transmission release valves deactivate the transmis-
sions so that the unit can be pushed by hand. See
PUSHING THE UNIT BY HAND for operational informa-
tion.
Seat Adjustment Knobs
The seat can be adjusted forward and backward. See
SEAT ADJUSTMENTS for adjustment information.

combustible materials.
Do not load this zero-turn rider on a trailer or
truck using two separate ramps. Only use a
single ramp that is at least one foot wider than
the width of the rear wheels of this rider. This
rider has a zero turning radius and the rear
wheels could fall off the ramps, or the rider could
tip over injuring the operator or bystanders.
Gasoline is highly flammable and must be
handled with care. Never fill the tank when the
engine is still hot from recent operation. Do not
allow open flame, smoking or matches in the area.
Avoid over-filling and wipe up any spills.
WARNING
If you do not understand how a specific control
functions, or have not yet thoroughly read the
FEATURES & CONTROLS section, do so now.
Do NOT attempt to operate the rider without first
becoming familiar with the location and function
of ALL controls.

Operation
9. Stop the engine (see STOPPING THE RIDER AND
ENGINE).
STARTING THE ENGINE
1. While sitting in the operator’s seat, make sure the
PTO switch is disengaged and the motion control
levers are locked in the NEUTRAL LOCKED position.
PUSHING THE RIDER BY HAND
1. Disengage the PTO, lock the motion control levers
into their neutral locked positions, turn the ignition
OFF, remove the key, and wait for all moving parts to
stop.
2. Set the engine speed control to FAST position. Then
fully close the choke. NOTE: A warm engine may not
require choking.
3. Insert the key into the ignition switch and turn it to
START.
2. To disengage the transmissions (free-wheel position),
push the roll release rods (A, Figure 2), located under
the rear of the unit behind each transmission, in
toward the transmission until the collar on the neck of
each rod passes through the keyhole in the roll
release plate, then lock the rod in the roll release
position by sliding the rod sideways into the keyhole
slot .
4. After the engine starts, gradually open the choke.
Warm up the engine by running it for at least a minute
before engaging the PTO switch or driving the rider.
5. After warming the engine, ALWAYS operate the
rider at FULL ENGINE SPEED when mowing.
In the event of an emergency the engine can be
stopped by simply turning the ignition switch to
STOP. Use this method only in emergency situations.
For normal engine shut down follow the procedure given
in STOPPING THE RIDER.
4. Move the motion control levers from their neutral
locked positions.
The rider can now be pushed by hand.
5. After moving the rider, re-engage the transmissions
(drive position) by unlocking the roll release rods and
pulling them out .
STOPPING THE RIDER & ENGINE
1. Returning the motion control levers to the middle (or
neutral drive) position will stop rider movement. Pivot
the levers outward to lock them in the NEUTRAL
LOCKED position.
DO NOT TOW RIDER
Towing the unit will cause transmission dam-
age. Do not use another vehicle to push or
pull this unit.
Note: Locking the motion control levers in their neutral
locked positions engages the parking brake.
2. Disengage the PTO by pushing down on the PTO
switch.

Operation
Smooth Travel
ZERO TURN
The motion control levers
of the zero turn rider are
responsive .
DRIVING PRACTICE
The motion control levers of the zero turn rider are
responsive, and learning to gain a smooth and efficient
control of the rider’s forward, reverse, and turning move-
ments will take some practice.
The BEST method of han-
dling the ground speed
levers is in three steps —
as shown in Figure 3.
Spending some time going through the maneuvers
shown and becoming familiar with how the unit acceler-
ates, travels, and steers — before you begin mowing —is
absolutely essential to getting the most out of the zero
turn rider.
FIRST place your hands
onto the levers as shown.
SECOND, to go forward
gradually push the levers
forward with your palms.
Locate a smooth, flat area of your lawn — one with
plenty of room to maneuver. (Clear the area of objects,
people and animals before you begin.) Operate the unit
at mid-engine speed during this practice session
(ALWAYS operate at full engine speed when mowing),
and turn slowly to prevent tire slippage and damage to
your lawn.
THIRD, to speed up move
the levers farther forward.
To slow down smoothly,
slowly move the levers
toward neutral.
We suggest you begin with the Smooth Travel procedure
to the right, and then advance through the forward,
reverse, and turning maneuvers.
Figure 3. Move Control
Levers Gradually
BASIC DRIVING
Forward Travel Practice
Reverse Travel Practice
Gradually move both motion control levers — evenly
FORWARD from neutral. Slow down and repeat.
LOOK DOWN & BEHIND, then gradually move both
motion control levers evenly BACK from neutral. Slow
down and repeat.
NOTE: Straight forward travel takes practice. If neces-
sary, top speed can be balance-adjusted — see the
Speed Balancing Adjustment in the Adjustments section
near the back of this manual.
NOTE: Practice backing up for several minutes before
attempting to do so near objects. The rider turns as
sharply in reverse as when going forward, and backing
up straight takes practice.

control lever forward from neutral and one lever back
from neutral simultaneously. Repeat several times.
NOTE: To prevent pivoting directly on the tire tread, it is
best to keep both wheels going at least slightly forward.
NOTE: Changing the amount each lever is pulled—for-
ward or back, changes the “pivot point” you turn on.

ADVANCED DRIVING
Executing an End-Of-Row Zero
Turn
Your zero turn rider’s unique ability to turn in
place allows you to turn around at the end of
a cutting row rather than having to stop and Y-
turn before starting a new row.
For example, to execute a right end-of row
zero turn:
1. Slow down at the end of the row.
2. Move the LEFT motion control lever for-
ward slightly while moving the RIGHT
motion control lever back to center and
then slightly back from center.
3. Begin mowing forward again.
This technique turns the rider RIGHT and
slightly overlaps the row just cut —eliminating
the need to back up and re-cut missed grass.
As you become more familiar and experi-
enced with operating the zero turn rider, you
will learn more maneuvers that will make your
mowing time easier and more enjoyable.
Remember, the more you practice, the bet-
ter your control of the rider will be!

Operation
ATTACHING A TRAILER
The maximum weight of a towed trailer should be less
than 200 lbs (91kg). Secure the trailer with an appropri-
ately sized clevis pin (A, Figure 9) and clip (B).
A
Excessive towed loads can cause loss of traction and
loss of control on slopes. Reduce towed weight when
operating on slopes. The surface being driven on greatly
impacts traction and stability. Wet or slippery surfaces
can greatly reduce traction and the ability to stop or turn.
Carefully evaluate the surface conditions before operat-
ing the unit and trailer, and never operate on slopes
greater than 10°. See SLOPE OPERATION and TOWED
EQUIPMENT in the safety section of this manual for
additional safety information.

CHECK TIRE PRESSURES
Tire pressure should be checked periodically, and main-
tained at the levels shown in the chart. Note that these
pressures may differ slightly from the “Max Inflation”
stamped on the side-wall of the tires. The pressures
shown provide proper traction, improve cut quality, and
extend tire life.
CHECKING / ADDING FUEL
To add fuel:
Tire
Front
Rear
Pressure
25 psi (1,72 bar)
15 psi (1,03 bar)
1. Remove the fuel cap.
2. Fill the tank to the bottom of the filler neck. This will
allow for fuel expansion.
Figure 17. Checking Tire Pressure

end out (counterclockwise) one to two turns to length-
en the link rod.
5. Retighten the jam nut, and reconnect the rod end to
the control bracket weldment.
6. Start the unit and check for transmission creep.
Repeat steps 2-5 if necessary.
7. Once the correct adjustment is achieved, check
adjustment of the compression spring (F). With the
motion control levers in their neutral locked positions,
the spring should have no compression, and should
have approximately 1/16-1/8” of free play between the
washers at either end. Turn the two adjustment nuts
(G) in or out until the desired adjustment is achieved.
WARNING
Incorrect adjustment of the compression springs
can cause motion control levers to move from
neutral into forward or reverse. This can cause
unexpected machine movement, and may result in

LESS PRE-LOAD:
• Light operator weight
• Softer, more cushioned ride
• Best for relatively flat terrain
MORE PRE-LOAD:
• Heavy operator weight
Figure 24. Front Suspension Adjustment
A. Pre-Load Adjustment Collar
• Stiffer, more rigid ride
• Better handling and greater stability on hilly terrain
TO ADJUST THE SPRING PRE-LOAD:
2. See Figure 24. Turn the pre-load adjustment collar
(A) CLOCKWISE to increase the pre-load, turn
COUNTER-CLOCKWISE to decrease the pre-load.
Make sure both shocks are set to the same amount

PTO CLUTCH ADJUSTMENT
WARNING
To avoid serious injury, perform adjustments only
with engine stopped, key removed and rider on
level ground.
Check the PTO clutch adjustment after the initial 25 hour
break-in period and then after every 250 hours of opera-
tion. Also perform the following procedure if the clutch is
slipping or will not engage, or if a new clutch has been
installed.
1. Remove key from ignition switch and disconnect
spark plug wires to prevent the possibility of acciden-
tal starting while the PTO is being adjusted.
BLADE BRAKE CHECK
Mower blades and mower drive belt should come to a
complete stop within five seconds after electric PTO
switch is turned off.
2. See Figure 25. Note the position of the 3 adjustment
windows (A) in the side of the brake plate and the
nylock adjustment nuts (B).
1. With parking brake engaged, PTO disengaged and
an operator in the seat, start the engine engine.
3. Insert a .016”-.018” (0,40-0,45mm) feeler gauge (C)
through each window, positioning the gauge between
the rotor face and the armature face as shown in
Figure 26.
2. Have an assistant observe the mower drive belt
through the opening between the frame and top of
mower deck. Engage the PTO and wait several sec-
onds. Disengage the PTO and check the amount of
time it takes for the mower drive belt to stop.
4. Alternately tighten the adjustment nuts (B, Figure 25)
until the rotor face and armature face just contacts
the gauge.
3. If the mower drive belt does not stop within five sec-
onds, perform the PTO Clutch Adjustment. If the belt
still does not stop within 5 seconds, see your dealer.
5. Check the windows for an equal amount of tension
when the gauge is inserted and removed, and make
any necessary adjustments by tightening or loosen-
ing the adjustment nuts.
NOTE: The actual air gap between the rotor and arma-
ture may vary even after performing the adjustment pro-
cedure. This is due to dimensional variations on compo-
nent parts, and is an acceptable condition.
6. Check the mower blade stopping time. The mower
blades and mower drive belt should come to a com-
plete stop within five seconds after the electric PTO
switch is turned off.

1. First level the mower deck using the procedure found
in MOWER DECK LEVELING.
2. With the mower installed, place the rider on a
smooth, level surface such as a concrete floor. Turn
the front wheels so they are straight.
3. Place the cutting height adjustment lever in the top
adjustment notch.
4. Measure the distance between the outside ends of
the roller bar and the ground. If there is more than
1/8” (3mm) difference between the measurements on
each side, proceed to step 5.
5. Locate the roller bar leveling hardware on the right
side of the mower deck (A, Figure 32). Loosen the
hardware and raise or lower the roller bar until the
correct level is achieved, then tighten the hardware.
Repeat steps 4 & 5 if necessary.

Remove the battery from the rider and place on a level,
non-concrete surface. Charge the battery at 6-10 amps
for 1 hour. Do not charge at a rate higher than 10 amps.
BATTERY CHARGING
A dead battery or one too weak to start the engine may
be the result of a defect in the charging system or other
electrical component. If there is any doubt about the
cause of the problem, see your dealer. If you need to
replace the battery, follow the steps under Cleaning the
Battery & Cables in the Regular Maintenance Section.
WARNING
Keep open flames and sparks away from the
battery; the gasses coming from it are highly
explosive. Ventilate the battery well during
charging.
To charge the battery, follow the instructions provided by
the battery charger manufacturer as well as all warnings
included in the safety rules sections of this book.

To avoid damaging belts, DO NOT
PRY BELTS OVER PULLEYS.
38” & 42” Decks:
1. Park the rider on a smooth, level surface such as a
concrete floor. Disengage the PTO, lock the motion
control levers into their neutral locked positions, turn
off the engine, and remove the ignition key.
2. Raise the mower deck to its highest cutting position.
3. Pull back firmly on the belt tensioning idler (E, Figure
34) in the direction indicated, and remove the belt
from the left arbor pulley (A).
4. (38” Decks Only) Loosen (do not remove) the hard-
ware securing the belt tensioning idler pulley to the
idler arm, just until the belt guide separates enough
from the pulley to allow the belt to slip between the
pulley and guide.
Note: The belt guide (A, Figure 35) has a locator tab
(B) that fits into a corresponding hole (D) in the idler
arm (C) and keeps the guide aligned correctly.
Should the idler assembly inadvertently come apart
while loosening, be sure the belt guide is correctly
reinstalled onto the idler arm.
5. Remove the old belt from the remaining pulleys.
6. Reversing steps 3 - 5, install the new belt, following
the routing in Figure 34. Be sure to retighten the idler
pulley hardware (if applicable).

Engine Power Rating Information
The gross power rating labels for individual gas engine models meet or exceed SAE (Society of Automotive
Engineers) code J1940 (Small Engine Power & Torque Rating Procedure) and rating performance has been obtained
and corrected in accordance with SAE J1995 (Revision 2002-05). Actual gross engine power may be lower and is
affected by, but not limited to, ambient operating conditions and engine to engine variability. Given both the wide array
of products on which engines are placed, and the variety of environmental issues applicable to operating the equip-
ment, the gas engine will not develop the rated gross power when used in a given piece of power equipment (actual
“on-site” or net horsepower). This difference is due to a variety of factors including, but not limited to, accessories (air
cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application limitations, ambient operating conditions
(temperature, humidity, altitude), and engine to engine variability.
