SERVICE / ADJUSTMENTS
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.
