shorten the linkage if the tire is creeping forward. Tighten the jam nuts at both ends. Release and
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.
