Tracking Adjustment

If the machine turns right or left when handles are pushed forward together, adjust the tracking plate on the side opposite the direction of turn (see Figure 47). Loosen the hardware that holds the tracking plate. Move the plate back until the unit drives straight. Tighten the hardware to lock the tracking plate in place. Readjust handles if necessary.

2.Move the motion control levers outward to the neutral position, engage parking brake, stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

3.Attach the hose coupling to the end of the mower washout fitting, and turn the water on high (Figure 48).
