SERVICE AND ADJUSTMENT
TRACKING ADJUSTMENT
IMPORTANT: DO NOT adjust the drive cables
in an attempt to resolve tracking issues. Cables
are set at the factory and should only be ad-
justed by authorized service retailers.
If the mower is not tracking straight, check the
air pressure in both rear tires. Recommended air
pressure is 15 psi. If the unit will not track
straight, follow the steps below. Tracking must
be checked on a flat and level concrete or
blacktop surface.
Mower is tracking to the right. Increase
the air pressure 2-3 psi in the right rear tire
or decrease the air pressure 2/3 psi in the
left rear tire.
Mower is tracking to the left. Increase
the air pressure 2-3 psi in the left rear tire
or decrease the air pressure 2/3 psi in the
right rear tire.
Recheck tracking and keep making adjustments
with the tire pressure until the unit tracks straight.
DO NOT exceed maximum recommended tire
pressure 24 psi.
Record the tire pressure for future reference.

With the park brake off the sping should
measure 2 3/4” both sides.
With the brake on the gap between the
connecting link and the secondary
linkage should be 1/2” on each side.
