distance between the steering lever and
hydrostatic transmission) several times.
If the wheel is moving in a reverse direction:
a. Loosen the jam nut on each end of the tie-rod.
b. Turn tie-rod clockwise (decreasing the distance
between the steering lever and hydrostatic
transmission) several times.

ADJUSTING THE UNIT TO TRACK

Check and adjust tire pressure. Increase pressure on
side unit tracks to. DO NOT exceed maximum
recommended tire pressure. See Specifications on
page 27 for correct tire pressure.
If tire pressure adjustment does not solve tracking
problem, adjust the limiter bolts on the stop bracket
(Figure 12). Front bolts adjust forward and rear bolts
adjust reverse. Lengthen the limiter bolt (move closer to
lever) on side which is too fast.

1. Shut OFF engine. Engage parking brake. Remove
the ignition key.
WARNING: This adjustment requires operating
the engine. Use extreme care to avoid contact
with moving parts and hot surfaces. Be sure
rear of unit is well supported and secure before
starting engine.
WARNING: Prior to adjusting the tracking of
the unit, shut OFF engine, engage parking
brake, and remove the ignition key.
