ADJUSTMENTS
WHEEL CREEP
"Creep" is when the engine is running and hydrostatic transmission
is in neutral, but due to inadequate alignment, 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. In the engine compartment, the hydrostatic transmission is on
the left side. The shift arm (D) is under the pump and comes
out the side. The idler arm (B) has a bearing that runs in the
notch of the shift arm. Loosen bolt (A).
3. With engine running, move bearing (B) so it centers on the shift
arm (D) and 'wheel creep' stops.
4. Tighten all fasteners and test by using foot pedal linkage to see
that 'creep' is removed.
5. Turn engine off and lower machine.
