ADJUSTMENTS
WHEEL ‘CREEP’ ADJUSTMENT
‘Creep’ is when engine is running and hydrostatic transmission is in neutral, but due to inadequate alignment,
wheels still move. Do the following procedures to stop this motion.
1. Lift up and support machine so all wheels are off
the ground and can turn freely.
2. On the top of the pump there is a Creep Arm.
Loosen bolts.
3. With engine running adjust the creep arm side to
side in slot so centering arm centers on the swash
plate.
4. Tighten all fasteners and test by using foot pedal
linkage to see that the "creep" is removed.
5. Turn engine off and lower machine.
TO ADJUST FOOT PEDAL THROTTLE CABLE
1. Jack up unit so that all drive wheel are off the
ground. (Use jack stands)
2. Start the engine, make certain that the hand
throttle is in the idle position (1200 engine RPM).
3. Engine speed must increase as soon as the foot
pedal begins to move in either direction. At the full
forward position, the engine RPM must be 3600
RPM ± 100.
4. Minor adjustment can be made by backing out
(unscrewing) Retainer (Ref A) until you reach full
engine RPM with the foot pedal fully depressed in
the forward position. Be sure to recheck after the
nuts are fully tightened.
5. Major adjustment needs to be made by pulling the slack out of the cable. Loosen the screw in the wire
block on the engine that is clamped onto the end of the cable and sliding it up to the cable block that is
through the throttle plate. Do not let the throttle plate move to increase idle speed. Tighten the screw.
6. Test run to determine that there is no binding and that engine idle speed is 1200 RPM and that it is 3600
RPM at full forward position of the foot pedal.
