Adjusting the Traction Drive
for Neutral
The machine must not creep when the traction pedal is
released. If it does creep, adjust as follows:
1. Park the machine on a level surface, stop the engine,
and lower the cutting decks to the floor.
2. Jack up the machine until all the tires are off the shop
floor. Support the machine with jack stands to prevent
it from falling accidentally.
3. On the right side of the hydrostat, loosen the locknut
on the traction adjustment cam (Figure 43).

adjustment of the traction adjustment cam
can be performed. This could cause personal
injury.
Keep hands, feet, face, and other body parts

engine, and any rotating parts.
4. Start the engine and rotate the cam hex in either
direction until the wheels cease rotation.
5. Tighten the locknut to secure the adjustment.
6. Stop the engine. Remove the jack stands and lower the
