Regular Maintenance
Neutral Adjustment
If the tractor “creeps” while the ground speed control levers are locked in NEUTRAL, then it may be necessary to adjust the linkage rod.
1.Park the machine on a hard, level surface such as a concrete floor. Disengage the PTO, engage the parking brake, and turn off the engine.
CAUTION
This adjustment should not be performed while the machine is running.
2.The locking nuts (D, Figure 35) are to be used together to turn the rod. Loosen the jam nut that locks against the ball joint (B) and turn the linkage rod (A) to adjust:
•If the machine creeps forward, turn the rod clockwise (while standing at the rear of the machine, facing forward);
•If the machine creeps backward, turn the rod counter- clockwise (while standing at the rear of hte machine, facing foward).
3.Lock the jam nut (B) against the ball joint (C) when neutral is achieved.
4.Start the engine.
5.Disengage the parking brake and lock the ground speed control levers in the neutral position.
6.If the machine still “creeps,” repeat the Neutral Adjustment procedure. It may take several attempts to achieve neutral, depending on how much the machine creeps.
Return-to-Neutral Adjustment
Checking the Adjustment:
To determine if it is necessary to adjust the neutral return, perform the following steps.
1.Disengage the PTO, engage the parking brake and turn off the engine.
2.Move the ground speed control levers into the operating position, pull levers rearward and release.
3.Move the ground speed control levers out towards the neutral position. If the levers do not align with the notches in the neutral lock plate, it is necessary to adjust the neutral return rod.

Adjustment:
1.Loosen the set collar (B, Figure 36) locked against the return spring (A).
2.Lock the ground speed control levers in neutral.
3.Tighten set collar snug against the return spring.
4.Pull lever rearward and release to check that the lever stops aligned with notch in the neutral lock plate.
It is important to note that after every adjustment of the neutral return spring, the lever must be returned to locked position to properly check the neutral position.
