Adjusting the Right Side Linkage
1. Place the speed control lever in the neutral position.
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 tyre begins to
rotate forward (Figure 36).
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 36).
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 36).
7. Adjust spring length by turning nut at front of spring

Adjusting the Control Rod
Checking the Control Rod
1. With rear of machine still on jack stands and engine
running at full throttle, move the speed control lever
to the medium speed position.
Note:
The OPC levers must be held down whenever
the speed control lever is out of the neutral position
or the engine will kill.
2. Move the respective drive lever upward until it
reaches the neutral position and engage neutral locks.
3. If the tyre rotates in either direction, the length of
the control rod will need to be adjusted.
Adjusting the Control Rod
1. Adjust the rod length by releasing the drive lever
and removing the hairpin cotter pin and clevis pin.
Rotate the rod in the rod fitting (Figure 37).
2. Lengthen the control rod if the tyre is turning in
reverse and shorten the rod if the tyre is turning
forward.
3. Rotate the rod several turns if the tyre is rotating fast.
Then, adjust the rod in 1/2 turn increments.
4. Place the clevis pin into the drive lever (Figure 37).
