Section 2
6. Operator hearing protection is recommended,
particularly for continuous operation of the mower.
Wear suitable hearing protection. Prolonged exposure
to loud noise can cause hearing impairment or loss.
13. DO NOT operate without a chute deflector installed;
keep the deflector in lowest possible position.
14. Check the blade mounting bolts at frequent intervals
for proper tightness.
7. Keep the machine and attachments in good operating
condition. Keep all shields and safety devices in place.
If a shield, safety device or decal is defective or
damaged, repair or replace it before operating the
machine.
15. Make sure all hydraulic fluid connections are tight and
all hydraulic hoses and lines are in good condition before
starting the machine.
2.4 OPERATION CONSIDERATIONS
WARNING:
1. Know the function of all controls and how to stop
quickly.
This machine is equipped with an interlock
system intended to protect the operator and
others from injury. This is accomplished by
preventing the engine from starting unless the
operator is seated in the seat, the deck drive is
disengaged, and the speed control is placed in
the neutral position. The system also shuts off
the engine if the operator leaves the seat with
the mower running and the speed control is not
in the neutral postion. It will also shut off the
engine if the hopper is raised with the cutter deck
drive engaged. Never operate equipment with
the interlock system disconnected or
malfunctioning.
2. Reduce speed and exercise extreme caution on slopes
and in sharp turns to prevent tipping or loss of control.
Be especially cautious when changing directions on
slopes.
WARNING:
DO NOT operate on steep slopes. To check a
slope, attempt to drive up it (with cutter deck
down). If machine can drive up the slope without
the wheels slipping, reduce speed and use
extreme caution. ALWAYS FOLLOW OSHA
APPROVED OPERATION.
8. Be sure interlock switches are functioning correctly.
9. Fuel is flammable; handle with care. Fill fuel tank
outdoors. Never fill indoors. Use a funnel or spout to
inhibit spillage. Clean up any spillage before starting
the engine.
3. Do not stop or start suddenly. WHEN GOING UP
HILL OR DOWN HILL, MOW UP AND DOWN
THE FACE OF SLOPES, NEVER ACROSS THE
FACE.
10. DO NOT add fuel to a running or hot engine. An
explosion could occur. Allow engine to cool for several
minutes before adding fuel.
4. When using any attachment, never direct the discharge
of material toward bystanders or allow anyone near
the machine while in operation.
11. Keep flammable objects (cigarettes, matches, etc.), open
flames and sparks away from fthe uel tank and fuel
container.
5. Before attempting to start the engine, disengage power
to the cutter deck and engage the parking brake.
6. If the mower discharge ever plugs, shut off the engine,
remove the ignition key, and wait for all movement to
stop before removing the obstruction. Do not use your
hand to dislodge the clogged discharge chute. Use a
stick or other device to remove clogged material.
12. Equipment must comply with the latest requirements
per ANSI J137 and/or ANSI S279 when driven on
public roads.

7. Be alert for holes, rocks, and roots in the terrain and
other hidden hazards. Keep away from any dropoff.
Beware of overhead obstructions (low limbs, etc.),
underground obstacles (sprinklers, pipes, tree roots,
etc.). Cautiously enter a new area. Be alert for hidden
hazards.
2.5 MAINTENANCE CONSIDERATIONS
1. Never make adjustments to the machine with the engine
running unless specifically instructed to do so. If the
engine is running, keep hands, feet, and clothing away
from moving parts.
8. Disengage power to mower before backing up. Do not
mow in reverse unless absolutely necessary and then
only after observation of the entire area behind the
mower.
2. Remove the key from the ignition switch to prevent
accidental starting of the engine when servicing or
adjusting the machine.
3. Keep all nuts, bolts and screws tight to ensure the
machine is in safe working condition. Check blade
mounting bolts frequently to be sure they are tight.
9. DO NOT turn sharply. Use care when backing up.
10. Watch for traffic when crossing roads or operating near
roadways.
4. Do not change the engine governor settings or overspeed
the engine.
11. Mow only in daylight or good artificial light.
5. To reduce fire hazard, keep the engine free of grass,
leaves, excessive grease and dirt.
12. Take all possible precautions when leaving the machine
unattended, such as disengaging the mower, lowering
the attachments, setting the parking brake, stopping the
engine, and removing the key.
6. Hydraulic fluid is under high pressure. Keep body
and hands away from pinholes or nozzles that eject
hydraulic fluid under high pressure. Use only cardboard
or paper to search for leaks.
13. Disengage power to the attachments when transporting
or when not in use.
7. Hydraulic fluid under high pressure may have sufficient
force to penetrate skin and cause serious injury. If
hydraulic fluid is injected into the skin, it must be
surgically removed within a few hours by a doctor or
gangrene may result.
14. The machine and attachments should be stopped and
inspected for damage after striking a foreign object,
and damage should be repaired before restarting and
operating the machine.
15. DO NOT touch the engine or the muffler while the
engine is running or immediately after stopping. These
areas may be hot enough to cause a burn.
16. DO NOT run engine inside a building or confined area
without proper ventilation. Exhaust fumes are
hazardaous and could cause death.

4.2 SAFETY INTERLOCK SYSTEM
4.4 STARTING THE ENGINE
The mower is equipped with a safety interlock system
that prevents the engine from starting unless the deck
drive is disengaged and the speed control is in neutral.
The interlock system shuts off the engine if the operator
leaves the seat with the speed control not in the neutral
position and/or the cutter blades are engaged. It will also
shut the engine off if the cutter deck drive is engaged and
the hopper is raised.
CAUTION:
DO NOT USE STARTING FLUIDS. Use of starting
fluids in the air intake system may be potentially
explosive or cause a “runaway” engine condition
that could result in engine damage and/or personal
injury.
1. Be sure the fuel shutoff valve, located under the fuel
tank, is completely open. (See section 7-4.)
WARNING:
Never operate the mower with the interlock
system disconnected or malfunctioning. Do not
disengage or bypass any switch; injury to
yourself and others or property damage could
result.
2. Sit in the operator’s seat and place the speed control
in the neutral position.
3. Engage the parking brake.
4. If the engine is cold, adjust the engine choke as
needed.
4.3 INITIAL RUN-IN PROCEDURES (First
Day of Use or Approximately 10 Hours)
5. Adjust engine throttle control to about half engine
speed.
1. Check all belts for proper tension at 2, 4 and 8 hours.
2. Change the engine oil and oil filter after the first 5
hours of operation. (See Section 7.4.)
6. Turn the ignition key to the START position and
release the key as soon as the engine starts. Do not
hold the key in the START position for more than 15
seconds at a time. Allow at least 60 seconds between
each cranking attempt to prevent overheating of the
starter motor. Prolonged cranking can damage the
starter motor and shorten battery life.
3. Check hydraulic oil level in reservoir. (See Section
7.3.)
4. Check for loose hardware. Tighten as needed.
7. Allow engine to warm before operating the mower.
5. Check interlock system for proper operation. (See
Section 4.2.)
4.5 GROUND TRAVEL AND STEERING
6. Check tire pressure. Inflate tires if necessary.
-IMPORTANT-
If you are not familiar with the operation of a
machine with lever steering and/or hydrostatic
transmissions, the steering and ground speed
operations should be learned and practiced in
an open area, away from buildings, fences, or
obstructions. Practice until you are comfortable
with the handling of the machine before
attempting to mow. Learn the operation on flat
ground before operating on slopes.

Section 4
-IMPORTANT-
Forward Travel
Start practice with a slow engine speed and slow
forward travel.
-NOTE-
Use one hand on both steering levers as shown in
Figure 4-5 to minimize overcontrol.
Do not push the steering control levers forward
when traveling forward. They are only used to
steer the mower and to travel in reverse by
pulling back on the levers.
To travel forward with the mower, move the speed control
lever forward. Do not push the steering control levers
forward as they are used only for steering the mower left
or right. When the speed control is moved forward, the
mower will travel forward at the speed the control lever is
set at. To increase the speed, push the control lever
forward and to decrease the speed, pull the control lever
back. It is not necessary to hold the speed control in
position, since a friction system holds the lever in
position.
Learn to operate the mower with the left hand
on the steering levers and the right hand on
speed control as shown in Figure 4-5. Using
both hands on the steering levers often causes
overcontrol.
Learn to feather the steering controls to obtain
a smooth operating action. Jerky movements
tend to place extreme force on the drive pumps
and axles, as well as damage the lawns.
To stop the forward travel, pull the speed control lever
back to the neutral position.
Practice operating the mower until you can
make it go exactly where you are aiming.
In case of an emergency, such as loss of control,
stop the mower’s movement by quickly pulling
the speed control lever to the neutral position.
To steer the mower left while traveling forward, pull the
left steering lever back. The further the lever is pulled
back, the further the mower will turn left.
To steer the mower right while traveling forward, pull the
right steering control lever back. The further the lever is
pulled back, the further the mower will turn right.
-NOTE-
Smooth operation of the steering levers will
produce a smooth mower operation. While
learning the operation of the steering controls,
keep the travel speed low.
-IMPORTANT-
Do not travel forward over a curb. The mower
will hang up on the curb. Tilt the deck and
travel backwards over the curb at a 45 degree
angle. (see section 4.15 for cutter deck tilting
instructions)

4.6 ENGAGING THE DECK DRIVE (CUTTER
BLADES)
CAUTION:
1. Set the throttle at about 3/4 speed. Do not attempt to
engage the deck drive at high speed as this shortens
the electric clutch life — use only moderate engine
speed when engaging the deck drive.
Before backing up, observe the rear for persons
and obstructions. Clear the area before backing
up. Possible injury or property damage could
occur.
2. Engage the deck drive by pulling out on the switch
lever (Figure 4-6) then pushing the switch lever
forward to the engage position.
CAUTION:
UP FOR MOWER - ON
PULL OUT
Disengage power to the mower before backing up.
Do not mow in reverse unless absolutely
necessary and then only after observation of the
entire area behind the mower.
To travel in reverse, pull both handles all the way back.
Keep the travel speed low while traveling in reverse.
DOWN FOR MOWER - OFF
-NOTE-
The mower will not travel straight in reverse.
Slight adjustments must be made using the
steering controls.
Figure 4-6 Cutter Engage Switch
-NOTE-
To steer left while traveling in reverse, allow the left
steering control lever to move forward. The further the
control is allowed to move forward, the further the mower
will turn left.
If a squealing noise is heard when engaging or
disengaging the deck drive, it is caused by the
electric clutch plates meshing as the mower
comes up to speed.
To steer right while traveling in reverse, allow the right
steering control lever to move forward. The further the
control is allowed to move forward, the further the mower
will turn right.
3. To disengage the deck drive, pull the switch lever
down to the disengage position.
4. Always operate the engine at full throttle to properly
maintain cutting speed. If the engine starts to lug
down, reduce the forward speed and allow the engine
to operate at maximum RPM.
To stop the reverse travel, place the speed control lever in
the neutral position and allow the steering control levers
to return to the neutral position. If the mower is to be
parked, engage the parking brake.

4.7 HILLSIDE OPERATION
WARNING:
To minimize the possibility of overturning, the
least dangerous method of operating on hills and
terraces is to travel vertically up and down the
slope, not horizontally along the slope. Avoid any
unnecessary turns and travel at reduced speed.
1. The mower has been designed for good traction and
stability under normal mowing conditions. However,
caution must be used when traveling on slopes,
especially when the grass is wet. Wet grass reduces
traction and steering control.
Figure 4-8 Improper Operation on a Slope
4.8 PARKING THE MOWER
2. To inhibit tipping or loss of control, do not start or
stop suddenly, avoid unnecessary turns and travel at
reduced speed.
1. Place the speed control in the neutral position.
2. Slow the engine to idle speed.
3. Keep tires properly inflated.
4. Always travel up or down the slope, whenever
possible; NEVER across the slope. (See Figures 4-7
and 4-8.)
3. Engage the parking brake.
4. Turn the ignition key to the OFF position and remove
the key.
4.9 AFTER OPERATION
1. Wash the entire mower after each use. Do not use
high pressure spray or direct the spray onto electrical
components.
-IMPORTANT-
Do not wash a hot or running engine. Cold
water will damage the engine. Use compressed
air to clean the engine if it is hot.
2. Keep the entire mower clean to inhibit serious heat
damage to the engine or hydraulic oil circuit.
Figure 4-7 Proper Operation on a Slope
3. Check the drive belts for proper tension, alignment
and any signs of rubbing. Correct and adjust if
necessary.

4. Fill the fuel tank with fresh, clean fuel at the end of
every day of operation.
Grass Catching Operation
5. Check the tire pressure. Inflate tires if necessary.
CAUTION:
Never leave grass clippings in the hopper after
mowing. Wet or damp clippings will generate heat
as they decompose which may cause spontaneous
combustion to occur.
4.10 HOPPER/SIDE DISCHARGE
OPERATION
A control lever located on the left side of the tractor
selects either hopper discharge or side discharge to the
outside. When the lever is placed in the hopper position
(Figure 4-9), the side discharge is covered and the hopper
discharge is opened. When the lever is placed in the side
discharge position (Figure 4-10), the hopper discharge is
covered and the side discharge is opened.
1. Place the hopper/side discharge control lever in the
hopper discharge position (Figure 4-9).
2. With the hopper lowered, engage the deck drive.
When the deck drive is engaged, the grass delivery
spout, which is designed to distribute the grass
clippings through the inside of the hopper, will begin
to oscillate. If the spout does not oscillate, do not use
the grass catcher. Use the side discharge and then
have the oscillating spout system repaired.
-NOTE-
If the control lever sticks, push the release lever to
free it.
-NOTE-
The mower has an interlock switch that will
prevent the mower from starting if the hopper is
in the raised position. This interlock switch will
also shut the engine off if the hopper is raised
while the engine is running and the deck drive is
engaged.
3. Proceed to mow the lawn until the hopper is full. If
your mower is not equipped with the optional hopper
full alarm to tell you when the hopper is full, check
the hopper frequently when first using the grass
catcher. After operating with the grass catcher for
awhile, experience will tell you when the hopper is
full.

4. When dumping the hopper into a disposal area:
A.Disengage the deck drive.
WARNING:
Never operate the grass catcher with the
hopper back door open. Objects can be
thrown out the spout of the hopper with a
force that can cause injury to bystanders or
property damage.

2. If the blower intake becomes clogged, there could be
a distinct change in the sound of the blower and/or
the mower deck will begin to leave a trail of glass
clippings. The clogging will generally develop in the
back of the mower deck in the opening of the blower
chute. When clogging occurs at this point, it's
usually caused by something restricting the flow
throughout the entire system and the system should
be checked if a pattern develops.
4.12 MOVING MOWER WITH ENGINE
STOPPED
To “free-wheel” or move the mower around without the
engine running, place the dump valve handle in the
FREE-WHEEL position (Figure 4-2). Disengage the
parking brake and move the mower by hand. The lever
must be returned to the DRIVE position to drive the
mower.
3. Check the following:
4.13 RECOMMENDATIONS FOR MOWING
A. Check that the blades are properly installed for
correct rotation. See Section 7.
1. Do not mow with dull blades. A dull blade will tear
grass, resulting in poor lawn appearance and
requiring extra power.
B. Check that the cutting height is not too low.
When cutting thick, tall grass, lower cutting
height settings tend to restrict the airflow moving
into and under the deck.
2. Direct the side discharge away from sidewalks or
streets to minimize cleanup of clippings. When
mowing close to obstacles, direct the discharge away
from the obstacles to reduce the chance of property
damage by thrown objects.
C. Check that the deck housing and baffling is free
of grass and dirt buildup. Some material buildup
can be tolerated, but when a buildup occurs that
restricts the flow of air and grass clippings, the
mower deck must be cleaned.
3. Cut grass when it is dry and not too tall. Do not cut
grass too short (cut off 1/3 or less of existing grass
for best appearance). Mow frequently.
D. Check that the blades have enough flat section at
the blade tip. Sharpening of the blades will
remove this flat section and if too much is
removed, the air lift capability of the blade is
greatly reduced. Replace the blades if more than
1/3 of blade is removed at the blade tip. See
section 7.10.
4. Keep mower and discharge system clean.
5. When mowing wet or tall grass, mow the grass twice.
Raise the mower to the highest setting for the first
pass and then make a second pass to the desired
height.
E. Check the discharge chutes for accumulation of
dirt and material that would restrict flow. Clean
the discharge chutes as described above.
6. Use a slow travel speed for trimming purposes.
7. Operate the engine at or near full throttle for best
cutting. Mowing with a lower RPM causes the
mower to tear the grass. The engine is designed to be
operated at full speed.
F. Check the elbow inside the hopper for a buildup
of material in the radius.
G. Check that the screen in the hopper is not
plugged with materials. If plugged, remove and
clean screen as described in section 7.13.
8. Use the alternate stripe pattern for best lawn
appearance. Vary the direction of the stripe each
time the grass is mowed to avoid wear patterns in the
grass.
H. Remember, anything that restricts airflow or
material flow along the entire path from the
mower deck to the hopper can cause clogging.

A. Loosen both jam nuts (A & B, Figure 6-6) on the
adjusting rod (C).
-NOTE-
All turnbuckles have a left hand threaded nut and a
right hand threaded nut. The left hand nut is located
next to the ball joint that has a groove etched into its
outer surface.
B. Using a wrench on the hex portion of the
adjusting rod, turn the adjusting rod (C) in the
required direction to move the bellcrank against
the bushing. When the correct adjustment is
obtained, tighten the two jam nuts (A & B).
Figure 6-4 Neutral Position
2. Check that the speed control bellcrank (Figure 6-5) is
touching the bushing on the frame and that the block
on the speed control lever has engaged the neutral
switch (Figure 6-4). The switch button should not be
fully compressed. If the switch is engaged, but the
bellcrank is not touching the bushing, full speed will
not be obtainable.
C. Proceed with the Neutral Adjustment.
Neutral Adjustment
1. Locate the left hand speed control lever. Using a
ruler, check the distance between the ball joint and
the center of the pivot point of the lever (Figure 6-6).
The dimension must be 4-1/2 inches or be in the
center of the slot. If correct, proceed to step 2. If
incorrect, loosen the lock nut securing the ball joint to
the lever and relocate the ball joint to the correct
position.

wheels start to turn at the same time.
8. When the speed control lever is actuated, the mower
should travel in a straight line. If it travels straight,
perform the Tracking Adjustment procedures. If the
mower pulls to one side, it is an indication that one of
the wheels is coming out of neutral before the other.
This condition must be corrected as follows:
-NOTE-
This adjustment affects the tracking of the mower.
Turning the turnbuckle (J) one or two flats has an
adverse effect throughout the tracking range.
A. If the mower pulls to the right, it is an indication
that the left wheel is coming out of neutral before
the right wheel. If the mower pulls to the left, it
is an indication that the right wheel is coming out
of neutral before the left wheel.
If the mower pulls one way at slow speed and then
pulls the other way at fast speed, a tracking
adjustment needs to be done.

transmission drive belts are adjusted for the correct
tension.
The mower tracking should be adjusted if during low
speed the mower pulls in one direction and then pulls in
the opposite direction as you go faster.

1. If at full speed the mower pulls right, it is an
indication that the left wheel is turning too fast. To
adjust this condition, loosen the lock nut securing the
swivel joint (N, Figure 6-6) to the left hand control
lever. Move the linkage outward in the slot. This
will lengthen the control arm and cause it to stroke
the pump less, slowing down the left wheel.
Figure 6-7 Gap Measurement
2. If at full speed the mower pulls to the left, it is an
indication that the left wheel is turning too slow. To
adjust this condition, loosen the locknut securing the
swivel joint (N) to the left hand control lever. Move
the linkage inward in the slot. This will shorten the
control arm and cause it to stroke the pump more,
speeding up the left wheel.

either handle, adjust the gap as follows:
1. Shut off the mower’s engine and engage the parking
brake.
5. Loosen the two jam nuts (K & L, Figure 6-6) on the
left control linkage. Turn the turnbuckle (M) until a
gap of 3/4 inches is obtained between the handle and
the frame. Tighten the two jam nuts (K & L).
2. Tilt the mower deck and lock it in place with the two
deck prop rods. Refer to Section 4 for the correct
procedure.
6. Loosen the two jam nuts (N & P) on the right control
linkage. Turn the turnbuckle (Q) until the right
handle is in line with the left handle (Figure 6-6).
Tighten the two jam nuts (N & P).
3. Remove the two deck springs and swing the deck
spring bracket up. If this is not done, the bracket will
contact the control levers when the seat is raised.
