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 swash plate (D) is under the transmission and comes out
forward. The idler arm (B) has a bearing that runs in the notch of the
swash plate. Loosen bolt (A).
3. With engine running, move bearing (B) so it centers on the swash
plate (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.
