MAINTENANCE
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 MAINTENANCE
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
nearest authorized service center/department.
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.

F -20 0 30 32 40 60 80 100
C -30 -2; -1; ; 1'0 20 30 4;
TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
NOTE: Although multi-viscosity oils (5W30, 10W30 etc.
improve starting in cold weather, they will result in increased
oil consumption when used above 32°R 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.
TO CHANGE ENGINE OIL (See Fig. 29)
Determine temperature range expected before oil change.
All oil must meet API service classification SG-SL.
• Ensure 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 yellow cap from end of drain valve and install
the drain tube onto the fitting.

Unlock drain valve by pushing inward and turning
counterclockwise.
• To open, pull out on the drain valve.
• 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.
• Remove the drain tube and replace the cap onto to the
bottom fitting of the drain valve.
• 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.
Ensure dipstick cap is tightened securely for accurate
reading. Keep oil at "FULl" line on dipstick. Tighten
cap onto the tube securely when finished.
ENGINE OIL FILTER
Replace the engine oil filter every season or every other
oil change if the tractor is used more than 100 hours in
one year.
AIR FILTER
Your engine will not run properly using a dirty air filter.
Service air cleaner more often under dusty conditions.
See engine Manual.
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 damage from overheating. Clean
with a wire brush or compressed air to remove dirt and
stubborn dried gum fibers.
ENGINE COOLING SYSTEM
To ensure 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. Ensure 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.
MUFFLER
Inspect and replace corroded muffler and spark arrester (if
equipped) as it could create a fire hazard and/or damage.
SPARK PLUGS
Replace spark plugs at the beginning of each mowing
season or after every 100 hours of operation, whichever
occurs first. Spark plug type and gap setting are shown in
"PRODUCT SPECIFICATIONS" section of this manual.
