e)Tracking Adjustment
1.Stop engine and wait for all moving parts to stop. Raise rear of machine, remove jack stands, and carefully lower machine to the ground.
2.Check the drive tire pressures and tire circumferences. See 5.1.12.
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.
5.2.6Hydro 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 as shown in Figure 15. 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.

5.2.7Throttle Control Adjustment
a)Loosen cable clamp on engine and position throttle control (at the control console) within 1/4" (6 mm) from the upper end of the slot. Pull on cable assembly at lower end where it attaches to the engine until the throttle control arm contacts the stop screw. Secure cable with cable clamp.
b)Tension in throttle lever can be adjusted by adjusting the tightness of the lever pivot bolt, which is located under the console. See Figure 16.

5.2.9Park Brake Adjustment:
a)Shut off engine and wait for all moving parts to stop.
b)Disengage the park brake.
c)Remove the hairpin in the park brake linkage. Turn the linkage in the yoke until there is 3/16” (.48 cm) to 1/4” (.64 cm) clearance between the park brake tire bars and the tires with the park brake disengaged.
