We do not recommend using a garden
hose or pressure washer to clean your
tractor unless the engine and transmism
sion 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,
20 leaves and trash from tractor and mower.
