CUSTOMER RESPONSIBILITIES
TRANSAXLE COOLING
The fan and cooling fins of transmission 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 possible
damage to seals, no not use high pressure water or steam to
clean transaxle.
•
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
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
authorized service center/department.
V-BELTS
Check V-belts for deterioration and wear after 100 hours of
operation and replace if necessary. The belts are not adjust-
able. Replace belts if they begin to slip from wear.

CLEAN AIR SCREEN (See Fig. 14)
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.
Every 100 hours of operation (more often under extremely
dusty, dirty conditions), remove the blower housing and other
cooling shrouds. Clean the cooling fins and external surfaces
as necessary. Make sure the cooling shrouds are reinstalled.
NOTE: Operating the engine with a blocked grass screen,
dirty or plugged cooling fins, and/or cooling shrouds removed
will cause engine damage due to overheating.
TO CHANGE ENGINE OIL (See Fig. 14)
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.
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.
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.
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.

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 neces-
sary.
TO CLEAN BATTERY AND TERMINALS
Corrosion and dirt on the battery and terminals can cause the
battery to “leak” power.
•
Remove terminal guard.
• 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 petroleum jelly.
• Reinstall battery (See “CONNECT BATTERY” in the
Assembly section of this manual).
