Troubleshooting, Adjustment & Service

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 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.

MOWING HEIGHT ADJUSTMENT

The cutting height adjustment pin (A, Figure 31) controls the mower cutting height. The cutting height is adjustable between 1-3/4” (4,4 cm) and 4-1/2” (11,4 cm) in 1/4” (0,64 cm) increments.

1.Depress the deck lift foot pedal (B) until it locks into the 4-1/2” (11,4 cm) position.

2.Place the cutting height adjustment pin in the desired cutting height.

3.Depress the deck lift foot pedal then push the lock lever (C) towards the right to release the lock.

4.Release the deck lift foot pedal until it comes to rest against the cutting height adjustment pin.
