1.4 OPERATION
Although hazard control and accident prevention
partially are dependent upon the design and
configuration of the equipment, these factors are also
dependent upon the awareness and proper training of
the personnel involved in the operation, transport,
maintenance, and the storage of the equipment. It is
essential that all Operator Safety Mechanisms be
connected and in operating condition prior to use for
mowing.
1.4.1 Give complete, undivided attention to the
job at hand.
1.4.2 Mow only in daylight or good artificial
light, keeping away from holes and hidden hazards.
NEVER carry passengers. Do not operate the mower
when children or others are in the area!
1.4.3 When feasible, avoid operating the
equipment in wet grass especially on slopes.
1.4.4 Use caution when mowing and/or turning
on slopes as loss of traction and/or tip-over could
occur. The operator is responsible for safe operation
on slopes.

4. OPERATION INSTRUCTIONS
4.1 CONTROLS
4.1.1 Be familiar with all the controls before operating the mower.
4.1.2 Motion Control Levers: Located on each side of the console.
The left lever controls the left hydrostatic transaxle and controls the left rear drive wheel to go forward
and backward.
The right lever controls the right hydrostatic transaxle and controls the right rear drive wheel to go
forward and backward.
IMPORTANT: To begin movement (forward or backward), the operator must be in the seat.
14
When the levers are centered in the T-slot, the drive system is in the neutral position. With levers
moved out in the T-slot, the drive system is in the parking brake position. See Figure 4.
FIG 4
PARKING BRAKE POSITION
By moving both levers an equal amount forward or back from the neutral position, the machine
can be moved forward or backward in a straight line.
Movement of the left lever forward will cause the left drive wheel to rotate in a forward
direction. Movement of the right lever forward will cause the right drive wheel to rotate in a
forward direction. To stop forward travel, pull the lever back to the neutral position.
To turn left while moving forward, move the left lever back toward neutral to slow the left drive
wheel. To turn right while moving forward, move the right lever back toward neutral to slow the
right drive wheel.
To make a zero turn to the left, pull the left lever back beyond neutral while holding the right
lever slightly ahead of neutral.
To make a zero turn to the right, pull the right lever back beyond neutral while holding the left
lever slightly ahead of neutral.
Pulling the levers back from the neutral position will cause the respective drive wheels to rotate in
a reverse direction (when tension can be felt when moving into reverse from neutral).
To turn to the left while backing, move the left lever forward toward neutral. To turn to the right
while backing, move the right lever forward toward neutral.
POTENTIAL HAZARD
·Machine can spin very rapidly by positioning one lever too much ahead of the other.
WHAT CAN HAPPEN

On a warm engine, place the throttle midway between the "SLOW" and "FAST" positions and push
the choke to the " " (closed) position.
4.3.3 Engage PTO
POTENTIAL HAZARD
·The rotating blades under the mower deck are dangerous.
WHAT CAN HAPPEN
. Blade contact can cause serious injury or kill you.
HOW TO AVOID THE HAZARD
. DO NOT put hands or feet under the mower or mower deck when the blades are engaged.
17
POTENTIAL HAZARD
· An uncovered discharge opening will allow objects to be thrown in an operator’s or bystanders’
direction. Also contact with the blade could occur.
WHAT CAN HAPPEN
·Thrown objects or blade contact can cause serious injury or death.
HOW TO AVOID THE HAZARD
. Never operate the mower with the discharge deflector raised, removed, or altered unless there is a
grass collection system or mulch kit in place and working properly.
The PTO clutch push-pull switch engages the cutting blades. Be sure that all persons are clear of mower
deck and discharge area before engaging PTO.
IMPORTANT: Operator must be in seat before the PTO can be engaged.

when the unit is parked inside a building.
4.4 TRANSPORTING
4.4.1 Transporting a unit: Use a heavy-duty trailer or truck to transport the machine.
Lock brake and block wheels. Securely fasten the machine to the trailer or truck with straps, chains,
cable, or ropes. Be sure that the trailer or truck has all necessary lighting and marking as required by
law.
POTENTIAL HAZARD
·This unit does not have proper turn signals, lights, reflective markings, or a slow moving
vehicle emblem. These items are required to drive on a public street or roadway.
WHAT CAN HAPPEN
·Driving on a street or roadway without such equipment is dangerous and can lead to accidents
causing personal injury.
·Driving on a street or roadway without such equipment may also be a violation of state laws
and the operator may be subject to traffic tickets and /or fines.
HOW TO AVOID THE HAZARD
·Do not drive a unit on a public street or roadway.
18
POTENTIAL HAZARD
·Loading a unit on a trailer or truck increases the possibility of backward tip-over.
WHAT CAN HAPPEN
·Backward tip-over of the unit could cause serious injury or death.
HOW TO AVOID THE HAZARD
·Use extreme caution when operating a unit on a ramp.
·Use only a single, full width ramp: DO NOT use individual ramps for each side of the unit.
·If individual ramps must be used, use enough ramps to create an unbroken ramp surface wider
than the unit.
·DO NOT exceed a 15°angle between ramp and ground or between ramp and trailer or truck.
·Avoid sudden acceleration while driving unit up a ramp to avoid tipping backward.
·Avoid sudden deceleration while backing unit down a ramp to avoid tipping backward.
4.4.2 Loading a Unit: Use extreme caution when loading units on trailers or trucks.
One full width ramp that is wide enough to extend beyond the rear tire is recommended instead of
individual ramps for each side of the unit. The lower rear section of the tractor frame extends back
between the rear wheels and serves as a stop for tipping backward. Having a full width ramp provides
a surface for the frame members to contact if the unit starts to tip backward. If it is not possible to use
one full width ramp, use enough individual ramps to simulate a full width continuous ramp.
Ramp should be long enough so that the angles between the ramp and the ground and the ramp and the
trailer or truck do not exceed 15°.
DO NOT attempt to turn the unit while on the ramp, you may lose control and drive off the side.
Avoid sudden acceleration when driving up a ramp and sudden deceleration when backing down a
ramp. Both maneuvers can cause the unit to tip backward.
