SERVICE AND ADJUSTMENT

TO ADJUST PARK BRAKE

Before making any adjustments:

NOTE:Make sure the brake arm is engaged into brake sprocket on both sides. You can push the mower to make it engage into the sprocket. See Fig. 19.

•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.

•If not loosen the nut against the yoke and turn the secondary linkage using the double nuts until the 1/2” gap is achieved on both sides. See Figure 19.

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.
