Maintenance
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.
• Tracking Adjustment:
1. Stop engine and wait for all moving parts to
stop. Engage parking brake. Raise the rear of
the machine, remove jack stands and carefully
lower the machine to the ground. (Check the
drive tire pressure and tire circumference see
Check the Tire Pressures section.)
2. Run the unit and observe the tracking on a
level, smooth, hard surface such as concrete
or asphalt.
3. 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 links to either the “medium” or “heavy
duty” positions as shown in Figure 23. The spring
anchor links are attached to the upper rear corner
of the hydro drive shields on the left and right
hand sides of the machine.
Note: In the “medium” or “heavy duty”
positions, the drive lever forces at the upper
handle will also be increased.

between the park brake tire bars and the tires with
the park brake disengaged. Re-install the hairpin.
