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 (C, Figure 29).
Adjustment
1.Loosen the jam nut (B) locked against the clevis (A).
2.Turn the neutral return rod (C) to adjust handle position.
4.Pull lever rearward and release to check position again. Adjust as necessary to align levers with notches.
It is important to note that after every adjustment of the neutral return rod, the lever must be pulled rearward and released to properly check the neutral position.
5.Once the lever alignment has been adjusted, lock jam nut against the clevis.
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 30) 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 30) 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
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.
