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 auto-
motive type wax.
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,
