CLEANING
• Clean engine, battery, seat, finish, etc. of all foreign matter.
• Keep finished surfaces and wheels free of all gasoline,
oil, etc.
• Protect painted surfaces with automotive type wax.
We do not recommend using a garden hose or pressure
washer to clean your tractor unless the engine and trans-
mission 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.
