Troubleshooting, Adjustment & Service

NEUTRAL ADJUSTMENT

If the tractor “creeps” while the ground speed control levers are locked in NEUTRAL, then it may be necessary to adjust the control linkage.

NOTE: Perform this adjustment on a hard, level surface such as a concrete floor.

1.Disengage the PTO, engage the parking brake and turn off the engine.

2.Loosen the jam nuts (B, Figure 33) and turn the adjustment linkage (A) to adjust. If the machine creeps forward, turn the linkage CLOCKWISE (while standing at the rear of the machine, facing forward), if the machine creeps backward, turn the linkage COUNTER-CLOCKWISE.

3.Lock the jam nuts (B) when neutral is achieved.

NOTE: This adjustment should not be performed while the machine is running. It may take several attempts to achieve neutral, depending upon how much the machine creeps.

NEUTRAL POSITION AND RETURN SPRING ADJUSTMENT

To determine if it is necessary to adjust the neutral position, perform the following steps.

1.Disengage the PTO, engage the parking brake and turn off the engine.

2.Move the ground speed control levers in the operating position, pull levers rearward and release.

3.Move the ground speed control levers towards the neutral position. If the levers do not align with the notches in the neutral lock plate, it is necessary to adjust the reverse return bolts (A, Figure 34).

Neutral Position Adjustment

1.Loosen the jam nut (D, Figure 34) locked against the clevis.

2.Turn the reverse return bolt (A) clockwise to adjust handle rearward, counter-clockwise to adjust handle forward.

4.Pull lever rearward and release to check position again. Adjust as necessary to align levers with notches.

5.Once the lever alignment has been adjusted, lock jam nut against the clevis.

Return Spring Adjustment

After adjusting the neutral position, lock the levers in the neutral position and measure the reverse return spring (B, Figure 34) length. This should be 2-3/8” (6,03 cm) long. If not, hold the reverse return bolt (A) with a wrench while turning the spring position nut (C)

until the measurement is achieved.
