3. Make this adjustment for both sides.
e) Tracking Adjustment
1. Stop engine and wait for all moving parts to stop. 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
5.1.11.)
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.
5.2.7 Hydro Pump Spring Tension Setting
a) 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.
b) For a heavier drive setting, relocate the spring anchor link to either the
“medium” or “heavy duty” positions as shown in Figure 17. 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.
