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.
• 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 mainte­
nance is not required for the life of the transaxle. Should the
transaxle ever leak or require servicing, contact your near­
est 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
adjustable. Replace belts if they begin to slip from wear.
ENGINE
LUBRICATION
Only use high quality detergent oil rated with API service
classification SF or SG. Select the oil’s SAE viscosity g rade
according to your expected operating temperature.
SAE VISCOSITY GRADES
O’’ 30° 32° 40° 60° 80° 100°
°C -30” 20“ -10“ 0“ 10° 20° 30° 40°
TEMPERATURE RANGE ANTICIPATED 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 the first two hours of operation and
every 50 hou rs thereafter or at least once a year if the tractor
is not used for 50 hours in one year.
Checkthecrankcaseoil 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 (See Fig. 17)
Determine temperature range expected before oil change.
All oil must meet API service classification SF or SG.
• 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” on page 3 of this
manual.
• Use gauge on oil fill cap/dipstick for checking level. Be
sure dipstick is in all the way for accurate reading.
Keep oil at “FULL” line on dipstick.
CLEAN AIR SCREEN (See Fig. 19)
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.
AIR FILTER (See Fig. 18)
Your engine will not run properly using a dirty air filter.
Clean the foam pre-cleaner after every 25 hours of opera­
tion or every season. Service paper cartridge every 100
hours of operation or every season, whichever occurs first.
Service air cleaner more often under dusty conditions.
• Remove wing nut and cover.
• Remove seal and cartridge plate.
