Troubleshooting, Adjustment & Service

SPEED BALANCING ADJUSTMENT

If the rider veers to the right or left when the ground speed control levers are in the maximum forward position, the top speed of each of these levers can be balanced by turning the adjustment bolt(s) (A, Figure 28). Only adjust the speed of the wheel that is traveling faster.

To Reduce the Speed of the Faster Wheel

1.Loosen the flange nuts.

2.turn the top speed adjustment bolt COUNTER- CLOCKWISE to reduce the speed.

3.Retighten the flange nuts when adjustment is complete.

WARNING

DO NOT adjust the tractor for a faster overall speed forward or reverse than it was designed for.

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 (3) nuts 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 clevis (B, Figure 29) 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 clevis 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.
