BATTERY

Your tractor has a battery charging system
which is sufficient for normal use. However,

periodic charging of the battery with an au­

tomotive 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 dirtonthe battery and terminals
can cause the battery to “leak” power.

1. Disconnect BLACK battery cable first

then RED battery 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 petroleum

jelly.

5.

Reinstall battery (See “REPLACING

BATTERY" in the SERVICE AND AD­

JUSTMENTS section of this manual).

TRANSAXLE COOLING
Thetransmission fan and cooling fins should

be kept clean to ensure proper cooling.
Do not attempt to clean fan or transmission

while engine is running or while the trans­

mission is hot. To prevent possible damage

to seals, do not use high pressure water or

steam to clean transaxle.
• Inspect cooling fan to Ensure fan blades

are intact and clean.

• Inspect cooling fins for dirt, grass clippings

and other materials. To prevent damage to
seals, do not use compressed air or high
pressure sprayer to clean cooling fins.

TRANSAXLE PUMP FLUID

The transaxle was sealed at the factory and
fluid maintenance is not required for the life

of the transaxle. Should the transaxle ever
leak or require servicing, contact your nearest
Sears or other qualified service center.

V-BELTS

Check V-be Its for deterioration and wear after

100 hours of operation and replace if neces­

sary. The belts are not adjustable. Replace
belts if they begin to slip from wear.

ENGINE

LUBRICATION

Cniy 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.

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 opera­

tion 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 se­
curely 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 SG-SL.

• Be sure tractor is on level surface.
• Oil will drain more freely when warm.
• Catch oil in a suitable container.

1. Remove oil fill cap/dipstick. Be careful

not to allow dirt to enter the engine when
changing oil.

2. Slide oil drain extension from the docking

position on the engine blower housing
and extend outward from engine.

3. To open, twist cap counter-clockwise
4. After oil is drained completely, replace

cap and twist clockwise until it stops.

5. Re-attach oil drain extension to engine

blower housing.

6. Refill engine with oil through oil fill dipstick

tube. Pour slowly. Do not overfill. For ap­

proximate capacity see “PRCDUCT SP-
ECIFICATICNS” section of this manual.

7. Use gauge on oil fill 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 finished.
