ENGINE OIL FILTER
Replace the engine oil filter every season or every other oil
change if the tractor is used more than 100 hours in one year.
NOTE: If needed, remove lower dash covers using steps
from "Lower dash cover removal" section of this manual.
AIR FILTER
Your engine will not run properly using a dirty air filter. Ser-
vice 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 dam age from overheating. Clean
with a wire brush or compressed air to re move dirt and
stubborn dried gum fibers.
ENGINE COOLING SYSTEM
To ensure proper cooling, make sure the grass screen,
cooling fins, and other external 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 re moved
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 PLUGS
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
"PROD UCT SPECIFICATIONS" section of this manual.

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
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 outside tractor and mower.
