When the machine is on a flat level surface and motion control levers are in their neutral or neutral lock positions, there should be no machine movement. If movement is present, adjustment must be made to left and/or right transmission control rods (located to the left and right of the operator seat, under the control panels):

1.Remove the hair pin and washer securing the rod fitting to the Motion Control Lever pivot bracket. See Figure 4.1. Pull fitting end out from bracket.

2.Turn fitting clockwise one turn if machine moves in reverse, or counterclockwise if machine moves forward.

3.Replace fitting into hole, securing with washer and hair pin.

4.1.3.Tracking Adjustments

When both motion control levers are fully engaged in forward drive, the machine should move in a straight line. If the machine tracks (veers) left or right, a tracking adjustment must be made. Each motion control lever is equipped with a tracking adjustment plate. See Figure 4.1b. Moving the plate forward or backward adjusts the machine’s tracking:

1.If mower tracks to the left, loosen the two torx screws on the left adjustment plate, slide plate forward approximately 1/8”, and retighten screws. (If plate is already as far forward as it can go, loosen the right plate and slide back 1/8”.) Check machine tracking and repeat as needed.

2.If mower tracks to the right, loosen the two torx screws on the right adjustment plate, slide plate forward approximately 1/8”, and retighten screws. (If plate is already as far forward as it can go, loosen the left plate and slide back 1/8”.) Check machine tracking and repeat as needed.

3.In cases of severe tracking, one plate may need to be moved fully back and the other moved fully forward.
