Service / Adjustments

CAUTION: Before performing any service or adjustments do as follows:

1.Turn off PTO switch.

2.Position unit on smooth flat surface.

3.Place steering levers in outward, neutral-locked position.

4.Turn ignition key “OFF” and set parking brake.

5.Wait for all moving parts to stop and disconnect spark plug wire.

TRACKING

Adjustments to the unit may need to be made if the unit does not track in a straight line. The primary reason for the unit not tracking straight is incorrect or unbalanced tire pressure. Before making any adjustments first check and adjust the tire pressure. DO NOT EXCEED MAXIMUM RECOMMENDED TIRE PRESSURE.

ADJUST LINKAGE: Place steering levers outward locking them in the neutral position. Turn off engine and raise seat. Under the seat are (4) adjustment bolts. The two adjustment bolts toward the seat mount are adjustments for the forward travel. The two bolts toward the engine or are for the reverse travel. Clockwise movement for these adjustments will decrease or slow the travel speed of the individual side. Counterclockwise movement will increase the travel of the individual side. The linkage is factory set to maximum performance. Adjustment is made by rotating the adjustment bolt clockwise on the opposite side that the unit tracks toward. Adjust forward and reverse to track straight as needed. When accomplished adjustment to the steering levers may need to be done. This is made by loosening the the two bolts on the steering lever and aligning with the other. Travel of the steering levers from front to rear may be accomplished in the same manner.
