2. Place the right drive lever in the full forward position.
3. Adjust the right side linkage by turning the quick
track knob counterclockwise until the tire begins to
rotate forward (Figure 40).
4. 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 (Figure 40).
5. Hold the 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.
6. The spring that keeps tension on the knob should
normally not need adjustment. However if an
adjustment is needed, adjust the length of spring to
1 inch (26 mm) between the washers (Figure 40).

and removing the hairpin cotter pin and clevis pin.
Rotate the rod in the rod fitting (Figure 41).
2. Lengthen the control rod if the tire is turning in
reverse and shorten the rod if the tire is turning
