Maintenance

2.Loosen the front nut on left hydro control link as shown in Figure 16. Turn the rear control linkage adjusting nut counterclockwise until wheel rotates forward. Turn the rear nut of left control link clockwise 1/4 of a turn at a time, stopping to move the speed control forward and back to neutral, until left wheel stops rotating forward. Turn the nut an additional 1/2 turn and tighten the front jam nut making sure not to put a bind on the linkage. Make sure flat part of linkage is perpendicular to pin part of swivel. See Figure 16.

Drive Lever Linkage

Adjustment

1.With rear of machine still on jack stands and engine running at full throttle, 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 see Figure 17. If the tire rotates in either direction, the length of the drive lever linkage will need to be adjusted.

After adjusting the left hydro control linkage, move the speed control lever to the mid-speed position and then back to the neutral position. Recheck the left drive wheel rotation to see if further adjustment is necessary - be sure the speed control lever is in the neutral position.

Important: If inconsistent neutral occurs, check to be sure both springs are properly tightened on the speed control lever under the console–especially the rear pivot spring.

3.Place the speed control lever in neutral. Adjust the right side linkage by turning the quick track knob counterclockwise until the tire begins to rotate forward. Begin to retighten the knob clockwise about 1/4 turn at a time, stopping to move the speed control forward and back 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 washers. Adjust spring length by turning nut at front of spring.

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 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. Raise rear of machine, remove jack stands, and carefully lower machine to the ground.

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.
