AIR FILTER 
Your engine will not run properly using a dirty air filter. Ser-
vice air cleaner more often under dusty conditions.
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 
fibers.
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 transaxle was sealed at the factory and fluid 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 
classification SG-SL.  Select the oil’s SAE viscosity grade 
according to your expected operating temperature.
NOTE:  Although multi-viscosity oils (5W30, 10W30 etc.) 
improve starting in cold weather, they 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 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. 17) 
Determine temperature range expected before oil change.  
All oil must meet API service classification C.
•  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.
• 
Slide oil drain extension under oil drain hole (drain hole 
may be flush with or protrude from engine block side wall).
• 
Make sure back face of oil drain extension is flush 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.
• 
Slide a 1/2” (12 point) socket mounted on an extension 
onto oil drain plug.
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.
CAUTION: If engine has been operated 
for an extended period of time immedi-
ately prior to draining oil, oil will be hot.

PLUG
• 
Loosen plug while holding the oil drain extension firmly 
in place.
•  Drain oil into container.
• 
After oil has drained completely, reinstall oil drain plug.  
(Do not tighten more than 13 Ft-Lb's)
•  Refill engine with oil through oil fill dipstick tube. Pour 
slowly. Do not overfill. For approximate capacity, see 
“PRODUCT SPECIFICATIONS” section of this man u al.
•  Use gauge on oil fill cap/dipstick for checking level.  
Be sure dipstick cap is tightened securely for accurate 
reading.  Keep oil at “FULL” line on dipstick. Tighten 
cap onto the tube securely when finished.
ENGINE COOLING SYSTEM (See Fig. 18)
Debris may clog the engine's air cooling system. Remove 
blower housing and clean the area shown to prevent over-
heating and engine damage.
