Section 4
3. To 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.
5. To properly burnish the electric PTO clutch brake,
follow the following steps.
A. Start and run the engine at approximately 3/4
throttle.
B. Engage and disengage the PTO
approximately 25 times, waiting for 10
seconds between each on/off cycle.
-NOTE-
Burnishing the electric clutch improves
longevity and performance and should be done
on every new machine and after a clutch
replacement. The burnishing procedure should
not be performed while cutting grass.
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. 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. To prevent tipping or loss of control, start and stop
smoothly, avoid unnecessary turns and travel at
reduced speed.
WARNING:
3. Keep tires properly inflated.
4.8 PARKING THE MOWER
1. Stop on level ground and place the steering control
levers in the neutral position.
2. Disengage the cutter blades
3. Slow the engine to idle speed.
4. Engage the parking brake.
5. 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.
4. After the mower has cooled down, fill the fuel tank
with fresh, clean fuel with a minimum cetane rating
of 40 at the end of every day of operation.
5. Check the tire pressure. Adjust pressure if
necessary.
To avoid injury from burns, allow the mower to cool
before removing the fuel tank cap and refueling.
