Right Side Linkage Adjustment
1. Place the speed control lever in the neutral position.
2. Place the right drive lever in the full forward position.
3. Hold OPC levers down.
Note: The OPC levers must be held down whenever the
speed control lever is out of the neutral position or the
engine will kill.
4. Adjust the right side linkage by turning the quick track
knob counter–clockwise until the tire begins to rotate
forward (Fig. 44).
5. Turn the knob clockwise 1/4 of a turn at a time. Then
move the speed control forward and back to neutral.
Repeat this until right wheel stops rotating forward
(Fig. 44).
6. The spring that keeps tension on the knob should
normally not need adjustment. However if adjustment
is needed, adjust the length of spring to 1 in. (26 mm)
between the washers (Fig. 44).
7. Adjust spring length by turning nut at front of spring
(Fig. 44).
