To adjust parking brake

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.

Before making any adjustments:

•With the park brake off the sping should measure 2 3/4’’ (70 mm) both sides.

•With the brake on the gap between the connecting link and the secondary linkage should be 1/2’’ (13 mm) on each side.

•If not loosen the nut against the yoke and turn the secondary linkage using the double nuts until the 1/2’’ (13 mm) gap is achieved on both sides. See Figure.

Tracking adjustment

If the mower is not tracking straight, check the air pressure in both rear tires. Recommended air pressure is 15 psi (1 bar). 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 (0.1-0.2 bar) 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 (0.1-0.2 bar) 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.
