We do not recommend using a garden hose
or pressure washer to clean your tractor
unless the engine and transmission are
covered to keep water out. Water in engine
or transmission w_ll shorten the useful tile of
your tractor. Use compressed air or a leaf
blower to remove grass, leaves and trash
from tractor and mower.
