Section 2
This 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. Do not mow on wet grass. Wet grass
reduces traction and steering control.
Any or all parts of the Roll Over Protection System MUSTNOT be removed. Failure to adhere to this guideline could
result in injury or death.
The potential exposure of this seat belt to severe
enviromental conditions make it crucial to inspect the seat
belt system regularly .
It is recommended that the seat belt be inspected on a
daily basis for signs of damage. Any seat belt system that
shows cuts, fraying, extreme or unusual wear, significant
discoloration due to UV exposure, dirt or stiffness, abrasion
to the seat belt webbing, or damage to the buckle, latch
plate, hardware or any other obvious problem should be
replaced immediately .

levers to return to the neutral position. If the mower is to
be parked, place the handles in the neutral lock position
and engage the parking brake.
4.6 ENGAGING THE DECK DRIVE (CUTTER
BLADES)
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.
2. Engage the deck drive by pulling out on the yellow
switch, located on the instrument panel, (Figure 4-3)
to the engage position.
-NOTE-
A squealing noise may be heard when
engaging or disengaging the deck drive. It is
caused by the electric clutch plates meshing
as the mower comes up to speed. This is
normal.
Before backing up, obser ve the rear for persons
and obstructions. Clear the area before backing
up. P ossible injury or property damage could occur.
T o travel in reverse, pull levers inward out of the neutral
lock position and pull both handles back. Keep the travel
speed low while traveling in reverse.
-NOTE-
The mower may not travel straight in reverse.
Slight adjustments must be made using the
steering controls.
T o 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 quicker the
mower will turn left.

3. T o disengage the deck drive, push the switch in 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.
4.7 HILLSIDE OPERATION
WARNING:
DO NOT operate on steep slopes. T o check a slope,
attempt to back up it (with the cutter deck down). If
the machine can back up the slope without the
wheels slipping, reduce speed and use extreme
caution. ALWAYS FOLLOW OSHA APPROVED
OPERATION.
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. The Roll Over
Protection System is standard equipment for this
machine. See section 2.5, page 6 of this manual for
further details.
2. T o prevent tipping or loss of control, do not start or
stop suddenly, avoid unnecessary turns and travel at
reduced speed. If tires loose traction, disengage
blades and proceed slowly off the slope.
4.8 PARKING THE MOWER
1. Park the machine on a flat, level surface only. Do not
park the machine on an incline.
2. Place the steering control levers in the neutral
position.
3. Disengage the cutter blades.
4. Slow the engine to idle speed.
5. Engage the parking brake.
6. 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.
3. Check the drive belts for proper alignment and any
signs of wear. Correct and adjust if necessary.
3. A void sudden starts when mowing uphill. Sudden
starts may cause the machine to tip backwards.
4. Loss of traction may occur when traveling down hill.
Weight transfers to the front of the machine and may
cause the drive wheels to slip causing loss of braking
or steering.
5. Keep tires properly inflated.
T o avoid injury from b urns, allow the mo wer to cool
before removing the fuel tank cap and refueling.
4. After the mower has cooled down, fill the fuel tanks
with fresh, clean fuel at the end of every day of
operation. See Engine Owner's Manual for proper
octane requirements.
5. Check the tire pressure. Adjust pressure if necessary.

WARNING
4.10 REMOVING CLOGGED MATERIAL
ROTATING BLADES
NEVER PUT Y OUR HANDS INT O THE DISCHARGE
CHUTE FOR ANY REASON! Shut off the engine and
remove the key and only then use a stick or similar
object to remove material if clogging has occurred.
1. If the discharge chute becomes clogged, shut off the
engine and remove the ignition key . Using a stick or
similar item, dislodge the clogged material. Then
resume normal mowing.
4.11 MOVING MOWER WITH ENGINE
STOPPED
To “free-wheel” or move the mower around without the
engine running, place the dump valve levers in the FREEWHEEL position (Figure 4-2, page 13). Disengage the
parking brake and move the mower by hand. The dump
valve levers must be returned to the DRIVE position and
torqued to 7-10 ft/lbs to drive the mower.
4. Keep mower and discharge chute 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.
6. Use a slow travel speed for trimming purposes.
7. Operate the engine at 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.
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.
4.13 ADJUSTING CUTTING HEIGHT
The mower deck can be adjusted from a height of 1-inch
to 5-1/2 inches at 1/4-inch intervals. T o adjust the cutting
height:
4.12 RECOMMENDATIONS FOR MO WING
1. Do not mow with dull blades. A dull blade will tear
grass, resulting in poor lawn appearance and require
extra power.
2. The discharge chute must not be removed and must
be kept in the lowest position to deflect grass
clippings and thrown objects downward. 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.
WARNING
DO NOT OPERATE WITHOUT DISCHARGE CHUTE, MULCHING
KIT, OR ENTIRE GRASS CATCHER INSTALLED
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.
WARNING:
DO NOT adjust the cutting height with the mower
blades rotating. Disengage the power to the cutter
blades and then adjust cutting height.
1. Disengage the power to the cutter blades.
2. Push the cutting height adjustment foot pedal all the
way forward using your right foot until it locks in
place. (Figure 4-5, page 18)
3. Insert the lanyard pin into the cutting height index at
the desired cutting height. Push forward on the deck
lift foot lever, hold in place and lift up on the deck
release lever, (Figure 4-4). Slowly release the foot
pedal. A deck height decal is located on the cutting
height index as an aid in adjusting the deck to the
desired height. (Figure 4-5)
