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.

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 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.

AIR FILTER

Your engine will not run properly using a dirty air filter.

Service air cleaner more often under dusty conditions.

TRANSAXLE MAINTENANCE

The transmission fan and cooling fins should be kept clean

to assure proper cooling.
Do not attempt to clean fan or transmission while engine

is running or while the transmission is hot. To prevent pos-

si ble damage to seals, do not use high pressure water or

steam to clean transmission.

Inspect cooling fan to be sure fan blades are intact and

clean.

• Inspect cooling fins for dirt, grass clippings and other

materials. To prevent damage to seals, do not use com-

pressed air or high pressure sprayer to clean cool ing fins.

TRANSAXLE PUMP FLUID

The transaxle was sealed at the factory and fluid main te-

nance is not required for the life of the transaxle. Should

the transaxle ever leak or require servicing, contact your

near est au tho rized ser vice center/department.

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 stubborn dried gum fibers.

ENGINE COOLING SYSTEM (See Fig. 19)

Debris may clog the engine's air cooling system. Remove

blower housing and clean the area shown to prevent over-

heating and engine damage.

SPARK PLUGS

Replace spark plugs at the beginning of each mowing sea-

son or after every 100 hours of use, whichever comes first.

Spark plug type and gap setting is shown in "PROD UCT

SPECIFICATIONS" section of this manual.

TO CHANGE ENGINE OIL (See Fig. 18)

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.

Slide oil drain extension under oil drain hole (drain hole

may be flush with or protrude from engine block side wall).

Make sure back face of oil drain extension is flush with

engine side wall.

• Make sure bottom lip of oil drain extension is lined up

with bottom of oil drain hole.

CAUTION: If engine has been operated

for an extended period of time immedi-

ately prior to draining oil, oil will be hot.

Position a container to catch oil directly under front end

of oil drain extension.

Slide a 1/2” (12 point) socket mounted on an extension

onto oil drain plug.

Loosen plug while holding the oil drain extension firmly

in place.

• Drain oil into container.

After oil has drained completely, reinstall oil drain plug.

(Do not tighten more than 13 Ft. Lbs.)

• 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.

Be sure dipstick cap is tightened securely for accurate

reading. Keep oil at “FULL” line on dipstick. Tighten

cap onto the tube securely when finished.
