MAINTENANCE
NOTE: The original equipment battery on your tractor is
maintenance free. Do not attempt to open or remove caps
or covers. Adding or checking level of electrolyte
is not
necessary.
TO CLEAN BATTERY AND TERMINALS
Corrosion and dirt on the battery and terminals can cause
the battery to "leak" power.
Disconnect BLACK battery cable first then RED bat-
tery cable and remove battery from tractor.
•
Rinse the battery with plain water and dry.
•
Clean terminals and battery cable ends with wire brush
until bright.
Coat terminals with grease or petroleum jelly.
•
Reinstall
battery
(See "REPLACING
BATTERY" in
the SERVICE AND ADJUSTMENTS
section of this
manual).
V-BELTS
Check V-belts for deterioration and wear after 100 hours
of operation and replace if necessary. The belts are not
adjustable. Replace belts if they begin to slip from wear.
TRANSAXLE
COOLING
Keep transaxle free from build-up of dirt and chaff which
can restrict cooling.
ENGINE
LUBRICATION
Only use high quality detergent oil rated with API service
classification SF-SJ. Select the oil's SAE viscosity grade
according to your expected operating temperature.

NOTE: Although multi-viscosity oils (5W30, 10W30 etc.)
improve starting in cold weather, these multi-viscosity oils
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.
TO CHANGE ENGINE OIL (See Figs. 13 and 14)
Determine temperature range expected before oil change.
All oil must meet API service classification SF-SJ.
Be sure 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.
•
Unlock drain valve by pushing inward and turning
counterclockwise.

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 positionas 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-
ual.
•
Use gauge on oil fill cap/dipstick for checking level.
Be sure dipstick cap is tightened securely for accu rate
reading. Keep oil at =FULL" line on dipstick.
CLEAN
AIR SCREEN
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.
CLEAN
AIR
INTAKE/COOLING
AREAS
To insure 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. Make sure the cooling shrouds are
reinstalled.
NOTE: Operating the engine with a blocked grass screen,
dirtyor pluggedcoolingfins, and/orcooling shroudsremoved
will cause engine damage due to overheating.
