MAINTENANCE
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.
ENGINE
LUBRICATION
Only use high quality detergent oil rated with API service
classification SG-SL. Select the oil’s SAE viscosity grade
according to your expected operating temperature.
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 Figs. 11 and 12)
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.
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
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. For
accurate reading, insert dipstick into the tube and push
down firmly into place before removing. Keep oil up to,
but not over, the “FULL” line on dipstick. Push dipstick
down firmly into the tube when finished.

BATTERY
Your tractor has a battery charging system which is suf fi cient
for normal use. However, periodic charging of the battery
with an automotive charger will extend its life.
Keep battery and terminals clean.
Keep battery bolts tight.
Keep small vent holes open.
Recharge at 6-10 amperes for 1 hour.
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
nec es sary.
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 “CONNECT BATTERY” in the
Assembly sec tion of this manual).
