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 transmission 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.
