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. 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.
