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 adjusted 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. In- crease the air pressure 2-3 psi in the right rear tire or decrease the air pres- sure 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.
