Troubleshooting, Adjustment & Service
NEUTRAL ADJUSTMENT
If the tractor “creeps” while the ground speed control levers are locked in NEUTRAL, than it may be neces- sary 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.There are three (3) nuts on the linkage rod. The first two are to be used together to turn the rod and the third (towards the rear of the machine) is used to lock the rod in place. Loosen the third jam nut (B, Figure 27) and turn the adjustment linkage (A, Figure 27) 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
3.Lock the jam nut (B) 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.

NEUTRAL SPRING RETURN
ADJUSTMENT
This adjustment will tailor the “feel” of the control levers to the operator.
Each of the springs (A, Figure 28) has three adjustment holes (B, Figure 28). The closer the spring is located to the neutral return arm’s pivot (D, Figure 28), the less spring force will be felt by the operator while driving and will return to neutral slower.
The farther the spring is located from the neutral return arm’s pivot (D, Figure 28), the more spring force will be felt by the operator while driving and will return to neu- tral faster.
NOTE: These adjustments must be made to BOTH sides at the same time, and be placed in the SAME position to one another.
