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” 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, 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 fig. 17. 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 releasing the drive lever and removing
clevis pin and rotating the linkage in the lower swivel. Lengthen the
linkage if the tire is turning in reverse and shorten the linkage if the
tire is creeping forward. Rotate the linkage several turns if the tire is
rotating fairly fast. But as the adjustment gets closer, adjust the
linkage in 1/2 turn increments. Release and re-engage neutral lock
latch checking that the tire stops. Continue these process until the
tire is at a dead stop.

3. Replace the hairpin back into each clevis pin.
4. Make this adjustment for both sides.
e) Tracking Adjustment
1. Stop engine, Raise the rear of the machine, remove jack stands and
carefully lower the machine to the ground.
2. Check the drive tire pressures and tire circumferences. See 5.1.11.
3. Run the unit and observe the tracking on a level, smooth, hard
surface such as concrete or asphalt.
