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.

Cleaning
Washing the Underside of
the Mower
Service Interval: Before each use or daily
After each use, wash the underside of the mower to
prevent grass buildup for improved mulch action and
clipping dispersal.
1. Park the machine on a level surface and disengage
the blade control switch.
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).
Note: Spread petroleum jelly on the washout
fitting O-ring to make the coupling slide on easier
and protect the O-ring.
