Troubleshooting, Adjustment, & Service
TRANSMISSION PURGING
Purge the transmission if the unit is excessively noisy or
lacks drive in forward or reverse.
1. Elevate the rear end of the tractor using a chain hoist
or floor jack. Support the rear of the unit using jack-
stands. Elevate the unit just high enough for the rear
wheels to clear the ground.
2. Activate the seat switch, depress the clutch / brake
pedal, and start the engine. After the engine has
started, set throttle to IDLE.
3. Release the brake pedal and fully depress the for-
ward ground speed pedal.
4. While holding the forward ground speed pedal down,
engage and disengage the transmission release
valve lever (A, Figure 34) several times.
5. Fully depress the reverse ground speed pedal.
6. While holding the reverse ground speed pedal down,
engage and disengage the transmission release
valve lever (A) several times.
7. Engage the transmission release valve lever and
stroke the transmission from full forward to full
reverse several times.
8. Lower the tractor and test run for several minutes.
