Forward Speed Adjustment
(Figure 18)
NOTE: Reverse speed cannot be adjusted. If
unit tracks excessively left or right in reverse,
see your Dealer for repair.
IMPORTANT: The unit should track within 2
feet (0.61 m) of a straight line for 30 feet
(9.14 m).
The travel of the steering levers may need
adjustment if the unit turns to the right or left
when both steering levers are pushed as far
forward as possible.
NOTE: The side the unit turns toward
indicates that the wheel on that side is turning
slower than the other wheel. Either the wheel
that is turning faster needs to slow down or
the wheel that is turning slower needs to
speed up to allow the unit to travel in a
straight line.
1. Determine which way the unit turns.
2. Loosen jam nut on the adjustment bolt.
3. Adjust speed by:
• Turning adjustment bolt clockwise to
decrease steering lever travel.
• Turning adjustment bolt
counterclockwise to increase steering
lever travel.
4. Tighten the jam nut.
