4.2 SAFETY INTERLOCK SYSTEM
The mower is equipped with a safety interlock system
that prevents the engine from starting unless the deck
drive is disengaged, the steering control levers are in the
neutral position and the operator is in the seat. The
interlock system shuts off the engine if the operator leaves
the seat with the steering control levers not in the neutral
position and/or the cutter blades engaged and/or the
parking brake not engaged.
Never operate the mower with the interlock
system disconnected or malfunctioning. Do not
disengage or bypass any switch; injury to
yourself and/or others or property damage could
result.

4. Check for loose hardware. Tighten as needed.
5. Check interlock system for proper operation. (See
Section 4.2)
6. Check tire pressure. Adjust pressure if necessary.
(See Section 7.9)
4.4 STARTINGTHE ENGINE
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. Sit in the operator’s seat, fasten seat belt and place
the steering control levers in the neutral position.
2. Engage the parking brake.
3. If the engine is cold, choke the engine as needed.
4. Move the engine throttle control to about half engine
speed.
CAUTION:
5. Turn the ignition key to the STARTposition 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.
6. Allow engine to warm before operating the mower.
4.5 GROUNDTRAVEL AND STEERING
-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.
-IMPORTANT-
Start practicing with a slow engine speed and
slow forward travel. Learn to feather the
steering controls to obtain a smooth
operating action.
ForwardTravel
To travel forward with the mower, disengage the parking
brake, pull levers inward out of the neutral lock position
and slowly push the steering control levers forward an
equal distance. The further the steering control levers
are pushed forward the greater the forward speed will
be. To increase the speed, push the steering control
levers further forward and to decrease the speed, pull the
steering control levers back.
To stop the forward travel, pull the steering control levers
back 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 quicker the mower will turn left.

15
Section 4
To steer the mower right while traveling forward, pull the
right steering control lever back. The further the lever is
pulled back, the quicker the mower will turn right.
-NOTE-
Smooth operation of the steering levers will
produce 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 may hang up on the curb. Raise the
deck and travel backwards over the curb at a
45 degree angle. (see Section 4.1, item 12 for
cutter deck raising instructions)
Reverse Travel
Disengage power to the mower before backing up.
Donotmowin reverseunless absolutely necessary
and then only after observation of the entire area
behind the mower.
Before backing up, observe the rear for persons
and obstructions. Clear the area before backing
up.Possibleinjury or property damagecouldoccur.
To 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.
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 quicker the
mower will turn left.
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 quicker the
mower will turn right.
To stop the reverse travel, allow the steering control
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.

4.8 PARKINGTHE 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.
4.9AFTER 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. To disengage the deck drive, push the switch in to the
disengageposition.
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
DO NOT operate on steep slopes. To 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. Under no circumstances should the
machine be operated on slopes greater than 15
degrees. ALWAYS FOLLOW OSHA APPROVED
OPERATION.
1. 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. Wet grass reduces
traction and steering control. The Roll-Over
Protection System is standard equipment for this
machine. See Section 2.5, page 7 of this manual for
further details.
2. To prevent tipping or loss of control, do not start or
stop suddenly, avoid unnecessary turns and travel at
reduced speed. If tires lose traction, disengage
blades and proceed slowly off the slope.
3. Avoid 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.
WARNING:
4. Check the tire pressure. Adjust pressure if necessary.
