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 stub-
born dried gum fi bers.
V-BELTS
Check V-belts for deterioration and wear
after 100 hours of operation and replace
if necessary. The belts are not ad just able.
Re place belts if they begin to slip from
wear.
TRANSAXLE COOLING
Keep transaxle free from build-up of dirt
and chaff which can restrict cooling.

LUBRICATION
Only use high quality detergent oil rated
with API service classifi cation SF-SJ. Se-
lect the oil’s SAE viscosity grade accord-
ing to your expected operating tempera-
ture.
Check the crankcase oil level before start-
ing the engine and after each eight (8)
hours of operation. Tighten oil fi ll cap/
dipstick securely each time you check the
oil level.
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 25 hours of op-
eration or at least once a year if the tractor
is not used for 25 hours in one year.
NOTE: The original equipment battery on
your tractor is maintenance free. Do not
attempt to open or remove caps or cov ers.
Adding or checking level of elec tro lyte is
not necessary.
TO CLEAN BATTERY AND TER MI NALS
Corrosion and dirt on the battery and
terminals can cause the battery to “leak”
power.
1. Disconnect BLACK battery cable fi rst
then RED bat tery cable and remove
battery from tractor.
2. Rinse the battery with plain water and
dry.
3. Clean terminals and battery cable ends
with wire brush until bright.
4. Coat terminals with grease or pe tro -
leum jelly.
5. Reinstall battery (See “REPLACING
BATTERY" in the SERVICE AND AD-
JUST MENTS section of this manual).
TO CHANGE ENGINE OIL
Determine temperature range expected
before oil change. All oil must meet API
service classifi cation SF-SJ.
• Be sure tractor is on level surface.
• Oil will drain more freely when warm.
• Catch oil in a suitable container.
1. Remove oil fi ll cap/dipstick. Be careful
not to allow dirt to enter the engine
when changing oil.
2. Remove yellow cap from end of drain
valve and install the drain tube onto the
tting.

3. Un lock drain valve by pushing inward
slightly and turning counterclockwise.
4. To open, pull out on the drain valve.
5. After oil has drained completely, close
and lock the drain valve by pushing
inward and turning clock wise until the
pin is in the locked position as shown.
6. Remove the drain tube and replace the
cap onto the end of the drain valve.
7. Refi ll engine with oil through oil fi ll dip-
stick tube. Pour slowly. Do not overfi ll.
For approximate capacity see “PROD-
UCT SPEC I FI CA TIONS” section of this
man u al.
8. Use gauge on oil fi ll cap/dipstick for
checking level. For accurate reading,
tighten dipstick cap securely onto the
tube before removing dipstick. Keep oil
at “FULL” line on dipstick. Tighten cap
onto the tube securely when fi nished.
