TO CHANGE ENGINE OIL
Determine temperature range expected before oil change.
All oil must meet API service classification SG-SL.
• Be sure tractor is on level surface.
• Oil will drain more freely when warm.

NOTE: Although multi-viscosity oils (5W30, 10W30 etc.)
improve starting in cold weather, they will result in increased
oil consumption when used above 32°F. Check your engine
oil level more frequently to avoid possible engine damage
from running low on oil.
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. Tighten oil fill
cap/dipstick securely each time you check the oil level.
• Unlock drain valve by pushing inward and turning
coun ter clock wise.
• To open, pull out on the drain valve.
• After oil has drained completely, close and lock the
drain valve by pushing inward and turning clockwise
until the pin is in the locked position as shown.
• Remove the drain tube and replace the cap onto to the
bottom fitting of the drain valve.
• Refill engine with oil through oil fill dipstick tube. Pour
slowly. Do not overfill. For approximate capacity see
“PRODUCT SPECIFICATIONS” section of this man-
u al.
• Use gauge on oil fill cap/dipstick for checking level.
Be sure dipstick cap is tightened securely for accurate
reading. Keep oil at “FULL” line on dipstick. Tighten
cap onto the tube securely when finished.
CLEAN AIR SCREEN
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.
AIR FILTER
Your engine will not run properly using a dirty air filter.
Service air cleaner more often under dusty conditions.
See Engine Manual.
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.
MAINTENANCE
MUFFLER
Inspect and replace corroded muffler and spark arrester
(if equipped) as it could create a fire hazard and/or dam-
age.
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.

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 trans-
mission 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.
IN-LINE FUEL FILTER (See Fig. 14)
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.
