TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
Change the oil after every 50 hours of operation or at least
once a year if the tractor is not used for 50 hours in one year.
Check the crankcase oil level before starting the engine
and after each eight (8) hours of operation.
TO CHANGE ENGINE OIL (See Fig. 21 & 22)
Determine temperature range expected before oil change.
All oil must meet API service classification SG-SL.
•
Ensure tractor is on level surface.
•
Oil will drain more freely when warm.
•
Catch oil in a suitable container.
•
Remove oil fill cap/dipstick. Be careful not to allow dirt
to enter the engine when changing oil.
•
Remove yellow cap from end of drain valve and install
the drain tube onto the fitting.

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.
AIR FILTER
Your engine will not run properly using a dirty air filter.
Service air cleaner more often under dusty conditions.
See engine manual.
CLEAN AIR SCREEN
The air screen is over the air intake blower located on top
100
of engine. The air screen must be kept free of dirt and
chaff to prevent engine dam age from overheating. Clean
40
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.
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.
MUFFLER
Inspect and replace corroded muffler and spark arrester (if
equipped) as it could create a fire hazard and/or damage.
IN-LINE FUEL FILTER (See Fig. 23)
The fuel filter should be replaced once each season. If fuel
filter becomes clogged, ob struct ing fuel flow to car bu re tor,
re place ment is re quired.
•
With engine cool, remove filter and plug fuel line sec tions.
•
Place new fuel filter in position in fuel line with arrow
pointing towards carburetor.
•
Be sure there are no fuel line leaks and clamps are
properly positioned.
•
Immediately wipe up any spilled gasoline.
