Maintenance
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 inch (2.5 cm)
between the washers. Adjust spring length by
turning nut at front of spring.
• 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 (Figure 21). If the tire rotates in either
direction, the length of the drive lever link will
need to be adjusted.
Figure 21
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.
3. Make this adjustment for both sides.
4. Stop engine and wait for all moving parts
to stop. Raise rear of machine, remove jack
stands, and carefully lower machine to the
ground.
Tracking Adjustment
1. Stop engine and wait for all moving parts to stop.
2. Check the drive tire pressures and tire
circumferences as stated in Check the Tire
Pressures section in Maintenance.
3. Run the unit and observe the tracking on a level,
smooth, hard surface such as concrete or asphalt.
4. If the unit tracks to one side or the other, turn the
quick track knob. Turn the knob right to “steer”
right, turn the knob left to “steer” left.
Hydro Pump Spring Tension
Setting
1. For medium or heavy duty drive conditions such
as operation with a sulky on steep slopes, a higher
spring force may be required on the hydro pump
control arms to prevent the drive system from
stalling.
2. For a heavier drive setting, relocate the spring
anchor link as shown in Figure 13. The spring
anchor links are located under the engine deck on
the left and right hand sides.
Note: In “medium” or “heavy duty” positions,
the drive lever forces at the upper handle will also
be increased.
