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