V-BELTS
Check V-belts for deterioration and wear after 100 hours
of operation and replace if necessary. The belts are not
ad just able. Re place belts if they begin to slip from wear.
TRANSAXLE MAINTENANCE
The transmission fan and cooling fi ns should be kept clean
to ensure 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 fi ns 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 fi ns.
TRANSAXLE PUMP FLUID
The transaxle was sealed at the factory and fl uid 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.

C -30 -20 -10
TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL 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.
TO CHANGE ENGINE OIL (See Fig. 20 & 21)
Determine temperature range expected before oil change.
All oil must meet API service classifi cation SJ-SN.
• Ensure tractor is on level surface.
• Oil will drain more freely when warm.
• Catch oil in a suitable container.
• Remove oil fi ll cap/dipstick. Be careful not to allow dirt
to enter the engine when changing oil.
CAUTION: If engine has been operated
for an extended period of time immedi-
ately prior to draining oil, oil will be hot.
• Slide oil drain extension under oil drain hole (drain hole
may be fl ush with or protrude from engine block side wall).

• Make sure back face of oil drain extension is fl ush with
engine side wall.
• Make sure bottom lip of oil drain extension is lined up
with bottom of oil drain hole.
• Position a container to catch oil directly under front end
of oil drain extension.
• Using a 8mm allen head wrench loosen plug while
holding the oil drain extension fi rmly in place.
• Drain oil into container.
• After oil has drained completely, reinstall oil drain plug.
(Do not tighten more than 13 Ft. Lbs./17 Nm)
• Refi ll engine with oil through oil fi ll dipstick tube. Pour
slowly. Do not overfi ll. For approximate capacity see
"PRODUCT SPECIFICATIONS" section of this man u al.
• Use gauge on oil fi ll cap/dipstick for checking oil level.
For accurate reading do not screw down dipstick cap.
Keep oil at the top of the crosshatched mark on dipstick.
Tighten cap onto the tube securely when fi nished.
ENGINE OIL FILTER
Replace the engine oil fi lter every season or every other oil
change if the tractor is used more than 100 hours in one year.
AIR FILTER
100
Your engine will not run properly using a dirty air fi lter. Ser-
40
vice air cleaner more often under dusty conditions.
CLEAN AIR SCREEN
The air screen is over the air intake blower located on top
of engine. The 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 fi bers.
ENGINE COOLING SYSTEM
To ensure proper cooling, make sure the grass screen,
cooling fi ns, 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 fi ns and external
surfaces as necessary. Ensure the cooling shrouds are
reinstalled.
NOTE: Operating the engine with a blocked grass screen,
dirty or plugged cooling fi ns, and/or cooling shrouds re moved
will cause engine damage due to overheating.
MUFFLER
Inspect and replace corroded muffl er and spark arrester (if
equipped) as it could create a fi re hazard and/or damage.
