ADJUSTMENTS
HYDROSTAT ADJUSTMENTS
A turnbuckle-style hydrostat neutral adjustment is
provided.
Neutral:
1. Support the machine with the rear wheels off the
ground. Use jackstands or equivalent support.
Do not rely only on mechanical or hydraulic jacks.
2. Move the traction levers out into the neutral lock
position and raise the seat.
3. Disconnect the seat switch and temporarily
connect the two terminals with jumper wire J as
shown.
4. Start the engine and run at low speed.
5. Loosen jam nuts T at both ends of the
turnbuckle.
6. Rotate the turnbuckle until the corresponding
wheel stops turning. Lock the turnbuckle jam
nuts. Run the engine up to high idle to check the
adjustment. Readjust if necessary.
7. Repeat steps 5 and 6 for the opposite side.
8. Remove the jumper wire and reconnect the seat
switch.
Reverse Return:
1. Move traction levers out to the neutral lock
position and raise the seat.
2. Locknut U should be run on the bolt as far as it
will go.
3. Loosen jam nut Y. Adjust the clevis yoke by
turning the head of the bolt until the clevis pin just
makes contact with the rear of the slot in the
lever it connects with. Tighten jam nut Y.
4. Repeat steps 2 and 3 for the opposite side.
NOTE: A slight creep in reverse is acceptable
provided the wheel does not turn and the hydrostat
pump does not whine when the parking brake is on.
