ENGINE OiL FILTER
Replacethe engine oilfilter every season or
every other oil change
if the tractor is used
more than 100 hours in one year.
AIR FILTER
Your engine will not run properly using a
dirty air filter. Service air cleaner more often
under dusty conditions.
CLEAN AIR SCREEN
The air screen is over the air intake blower
located on top of engine. The air screen
must be kept free of dirt and chaff to prevent
engine damage from overheating. Clean with
a wire brush or compressed air to remove
dirt and stubborn dried gum fibers.
ENGINE COOLING SYSTEM
To ensure proper cooling, make sure the
grass screen, cooling fins, and other exter-
nal surfaces of the engine are kept clean
at all times.
Every 100 hours of operation (more often
under extremely dusty, dirty conditions),
remove the blower housing and other cooling
shrouds. Clean the cooling fins and external
surfaces as necessary. Ensure the cooling
shrouds are reinstalled.
NOTE: Operating the engine with a blocked
grass screen, dirty or plugged cooling fins,
and/or cooling shrouds removed will cause
engine damage due to overheating.
MUFFLER
Inspect and replace corroded muffler and
spark arrester (if equipped) as it could create
a fire hazard and/or damage.
SPARK PLUG(S)
Replace spark plugs at the beginning of
each mowing season or after every 100
hours of operation, whichever occurs first.
Spark plug type and gap setting are shown
in "PRODUCT SPECIFICATIONS" section

• Keep finished surfaces and wheels free
of all gasoline, oil, etc.
• Protect painted surfaces with automotive
type wax.
Except for the washout port (if equipped),
we do not recommend using a garden hose
or pressure washer to clean the outside of
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 outside tractor and mower.
