BATTERY

Your tractor has a battery charging
system which is sufficient 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 necessary.

TO CLEAN BATTERY AND TERMINALS

Corrosion and dirt on the battery and
terminals can cause the battery to “teak"
power,
• Open battery box door.
• Disconnect BLACK battery cable first

then RED battery 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 petro­

leum 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, SG, or

SH. Select the oil’s SAE viscosity grade
according to your expected operating

temperature.

TEMPERATURE RANGE ANTCIPATgD BEFORE NEXT OIL CHANGE

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

operation or at least once a year if the
tractor is not used for 25 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

Determine temperature range expected
before oil change. All oil must meet API
service classification SF, SG or SH.
• 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 drain plug.
• After oil has drained completely,

replace oil drain plug and tighten

securely.

• Refill engine with oil through oil fill

dipstick tube. Pour slowly. Do not

overfill. For approximate capacity see
“PRODUCT SPECIFICATIONS”
section of this manual.

• 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.

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.
