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 com-
pressed air to re move dirt and stubborn dried gum fi bers.
CLEAN AIR INTAKE/COOLING AREAS
To insure 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. Make sure the cooling shrouds are
reinstalled.
MAINTENANCE
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 COOLING
The transmission fan and cooling fi ns 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 transaxle.
• 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
compressed 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.

LUBRICATION
Only use high quality detergent oil rated with API service
classifi cation SF-SJ. 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.

TO CHANGE ENGINE OIL (See Fig. 16)
Determine temperature range expected before oil change.
All oil must meet API service classifi cation SF-SJ.
• Be sure 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.
• Remove yellow cap from end of drain valve and install
the drain tube onto the fi tting.
• Unlock drain valve by pushing inward and turning
coun ter clock wise.
• 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 fi tting of the drain valve.
• 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 level.
Insert dipstick into the tube and rest the oil fi ll 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 fi nished.
TO CLEAN BATTERY AND TERMINALS
Corrosion and dirt on the battery and terminals can cause
the battery to “leak” power.
• Disconnect BLACK battery cable fi rst then RED bat-
tery 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 sec tion of this manual).
