ADJUSTMENTS
WHEEL CREEP
"Creep" is when the engine is running and hydrostatic transmission is in neutral, but due to inadequate align -
ment, wheels still move. Do the following
procedure to stop this motion.
1. Lift up and support machine so rear
wheels are off the ground and can
turn freely.
2. On top of the pump there is a Creep
arm. Loosen bolt (Ref A) on creep
arm.
3. With engine running, adjust the 'creep
arm' side to side so centering arm
centers on the swash plate.
4. Tighten all fasteners and test by using
foot pedal linkage to see that 'creep'
is removed.
5. Turn engine off and lower machine.
