10.3 ENGINE FAN BELT ________________________________________________________
Inspect and adjust a new belt after the first ten hours of operation.
Check the belt every 100 hours after the first 10 hours.
Adjust the alternator position so that the belt moves 1/4 to 5/16 inch (0.6
to 0.8 cm) with a 20 lb. (89 N) push at the center point between pulleys.
Refer to the Engine manual.
If the belt tension is not correct, loosen the alternator mounting bolts
and adjust the alternator until the correct belt tension is set. Tighten the
alternator mounting bolts.
10.4 NEUTRAL ADJUSTMENT ___________________________________________________
The neutral adjustment is set at the factory on all new mowers and
replacement pumps. Additional adjustment is not necessary unless the
pump was disassembled for repair or service. Neutral adjustment is set at
the drive pump.
To adjust Neutral position -
a Disconnect the pedal linkage from the pump.
b Put the mower on jack stands. All four wheels must not touch the
ground.
c Make sure the tow valve is closed.
d Disconnect the seat switch and assemble the jumper wire to the wiring harness.
e Loosen the screws that hold the lever bracket enough to allow the bracket to move.
f Make sure the parking brake switch is in the ON position, the PTO switch is in the OFF position and the traction
pedal is in the NEUTRAL position. Start the engine.
g Turn the parking brake switch to the OFF position. Adjust the lever bracket until the wheels do not turn. Stop the
engine and tighten the bracket hardware to set the adjustment.
h Remove the jumper wire and connect the seat switch to the wiring harness.
i Lower the mower to the ground.
j Connect the pedal linkage to the pump. Check the neutral switch adjustment. Make sure that the neutral switch
LED on the controller is illuminated with the pedal in the NEUTRAL position.
k Start the engine and check the operation of the traction pedal. When the pedal is in the NEUTRAL Position, the
wheels must not turn.
WARNING
When the pedal linkage disconnected, hold the traction pedal in the NEUTRAL position until the engine is started.
When you turn the parking brake switch to the OFF position, the wheels will rotate. Use caution when you are near
the wheels.
