FIGURE 13
After adjusting the left hydro control linkage, move the speed control
lever to the mid-speed position and then back to the neutral position.
Recheck the left drive wheel rotation to see if further adjustment is
necessary - be sure the speed control lever is in the neutral position.
If inconsistent neutral occurs, check to be sure both springs are
properly tightened on the speed control lever under the console -
especially the rear pivot spring.
Repeat above adjustments if necessary.
3. Place the speed control lever in neutral. Adjust the right side linkage by
turning the quick track knob counter-clockwise until the tire begins to
rotate forward. Begin to retighten the knob clockwise about 1/4 turn at
a time, stopping to move the speed control forward and back to neutral.
Recheck the drive wheel rotation to see if further adjustment is
necessary.
4. The spring that keeps tension on the knob should normally not need
adjustment. However, if adjustment is needed, adjust to where length
of spring is about 1” (2.5 cm) between the washers. Adjust spring
length by turning nut at front of spring.
d) Drive Lever Linkage Adjustment
1. With rear of machine still on jack stands and engine running at full
throttle, disengage the park brake and move the speed control lever to
the midway position. Move the respective drive lever upward until it
reaches the neutral position and engage neutral lock latches. See
Figure 14. If the tire rotates in either direction, the length of the drive
lever link will need to be adjusted.
2. Adjust the linkage length by loosening the jam nuts at both ends of the
linkage and rotating the linkage in the ball joints. Lengthen the linkage
if the tire is turning in reverse and shorten the linkage if the tire is
creeping forward. Tighten the jam nuts at both ends. Release and re-
engage the neutral lock latch checking that the tire stops. Continue this
process until the tire is at a dead stop.
