replace if necessary. The belts are not adjustable. Re place 
belts if they begin to slip from wear.

TRANSAXLE COOLING

Keep transaxle free from build-up of dirt and chaff which 
can restrict cooling.

TO CHANGE ENGINE OIL (See Figs. 10 and 11) 

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.  

Be sure dipstick cap is tightened securely for accurate 
reading.  Keep oil at “FULL” line on dipstick.

YEL LOW CAP

ENGINE

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.

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 every 25 hours of operation or at least 
once a year if the tractor is not used for 25 hours in one 
year.

Check the crankcase oil level before starting the engine 
and after each eight (8) hours of operation.  Tighten oil fi ll 
cap/dipstick securely each time you check the oil level.   

MUFFLER   

Inspect and replace corroded muffl er and spark arrester 
(if equipped) as it could create a fi re hazard and/or dam-
age.

SPARK PLUGS 

Replace spark plugs at the beginning of each mowing sea-
son or after every 100 hours of use, whichever comes fi rst.  
Spark plug type and gap setting is shown in "PROD UCT 
SPECIFICATIONS" section of this manual. 

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.

AIR FILTER 

Your engine will not run properly using a dirty air fi lter. 
Service air cleaner more often under dusty conditions. 
See Engine Manual.

ENGINE COOLING FINS

Remove any dust, dirt or oil from engine cooling fi ns to 
prevent engine damage from overheating.  Hood and 
engine blower housing must be removed to clean engine 
cooling fi ns.
See Engine Manual.
