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.

1. Open battery box door.

2. Disconnect BLACK battery cable first

then RED battery cable and remove
battery from tractor.

3. Rinse the battery with plain water and

dry.

4. Clean terminals and battery cable

ends with wire brush until bright,

5. Coat terminals with grease or

petroleum jelly.

6. 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

TEMPE RATURE RANQ£ ANTICtPATEP BEFOBE NEXT OW- CHANGE

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

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.

1. Remove oil fill cap/dipstick. Be careful

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

2. Remove cap from end of drain valve

and install the drain tube onto the
fitting.

3. Unlock 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 clockwise until the

pin is in the locked position as shown.

6. Remove the drain tube and replace

the cap onto to the end of the drain
valve.

7. Refill engine with oil through oil fill

dipstick tube. Pour slowly. Do not
overfill. For approximate capacity see

“PRODUCT SPECIFICATIONS”

section of this manual.

8. Use gauge on oil fill cap/dipstick for

checking ievel. Insert dipstick into the
tube and rest the oil fill cap on the
tube. Do not thread the cap onto the
tube when taking reading. Keep oil
at “FULL” line on dipstick. Tighten cap
onto the tube securely when finished.

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.
