Adjusting the Right Side Linkage
1. With the machine on jack stands, place the
speed control lever in the neutral position.
2. Place the right drive lever in the full forward
position.
3. 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.
4. Adjust the right side linkage by turning the
quick track knob counterclockwise until the
tire begins to rotate forward (Figure 50).
5. Turn the knob clockwise a 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 50).
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 50).
7. Adjust the spring length by turning the nut at
the front of spring (Figure 50).
8. After adjusting the right hydro control linkage,
move the speed control lever forward and then
back to the neutral position.
9. Make sure the speed control lever is in the
