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 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 30).
Adjustment
1.Loosen the jam nut (B) locked against the ball joint (A).
2.Turn the neutral return rod (C) to adjust handle position (see Figure 30).
3.Pull lever rearward and release to check position again. Adjust as necessary to align levers with notches.
4.Once the lever alignment has been adjusted, lock jam nut against the ball joint.
PARKING BRAKE ADJUSTMENT
1.Disengage the PTO, stop the engine, block the front wheels, remove the ignition key, and engage the parking brake.
2.Locate the upper brake spring (A, Figure 31).
3.With the parking brake engaged, measure the compressed spring length. The spring should be
2” to
4.If the spring is not within this range, jack up the rear of the machine and secure with jackstands. Remove both drive tires.
5.Locate the lower brake spring and adjustment clevis (A & B, Figure 32).
6.Release the parking brake and disconnect the clevis (B) from the caliper lever (C). Turn the clevis to compress or release the upper spring. Lock the nut against the clevis and reinstall the clevis onto the caliper lever.
CAUTION
Do not adjust the spring to be shorter than 2” (5,0 cm) when compressed. This may damage the brake caliper.
