tractor.
AirFilter
The engine is equipped with a replaceable, high density
paper air cleaner element and an oiled, foam
precleaner. Always examine the air cleaner before
starting the engine. Check for a buildup of dirt and
debris around the air cleaner system. Keep this area
clean. Also check for loose or damaged components.
Replace all bent or damaged air cleaner components.
NOTE: Starting the tractor with loose or damaged air
cleaner components could allow unfiltered air into the
engine causing premature wear and failure.
