oil, etc.
• Protect painted surfaces with automotive type wax.
Except for the washout port (if equipped), we do not
recommend using a garden hose or pressure washer to
clean the outside of your tractor unless the engine and
transmission are covered to keep water out. Water in
engine or transmission will shorten the useful life of your
tractor. Use compressed air or a leaf blower to remove
grass, leaves and trash from outside tractor and mower.
CLEANING
• Clean engine, battery, seat, fi nish, etc. of all foreign
matter.
• Clean debris from steering plate. Debris can restrict
clutch/brake pedal shaft movement, causing belt slip
and loss of drive. (See Fig. 21)
CAUTION: Avoid all pinch points and
movable parts.
