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.

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.There are three nuts (B, Figure 31) on the linkage rod. The first two are to be used together to turn the rod and the third (towards the front of the machine) is used to lock the rod in place. Loosen the jam nut that locks against the ball joint (B, Figure 31) 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.

3.Lock the jam nut (B) against the ball joint when neutral is achieved.

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

RETURN-TO-NEUTRAL

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.

TO ADJUST:

1.Loosen the set collar (B, Figure 32) locked against the return spring (A).

2.Lock the ground speed control levers in neutral.

3.Tighten set collar 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.
