V-BELTS

Check V-belts for deterioration and wear after 
100 hours of operation and replace if neces-
sary. The belts are not ad just able. 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.

ENGINE

LUBRICATION

Only use high quality detergent oil rated 
with API service classifi cation SF-SJ.  Se-
lect 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 frequent-
ly to avoid possible engine damage from 
running low on oil.
Change the oil after every 50 hours of op-
eration 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 fi ll cap/dipstick se-
curely each time you check the oil level.   

1.   Disconnect BLACK battery cable fi rst  

then RED  bat tery cable and remove 
battery from tractor.

2.   Rinse the battery with plain water and dry.
3.   Clean terminals and battery cable ends 

with wire brush until bright.

4.   Coat terminals with grease or pe tro -

leum jelly.

5.   Reinstall battery (See “REPLACING 

BATTERY" in the SERVICE AND AD-
 JUST MENTS section of this manual).

TO CHANGE ENGINE OIL 
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.
1.   Remove oil fi ll cap/dipstick.  Be careful 

not to allow dirt to enter the engine 
when changing oil.

2.   Remove yellow cap from end of drain 

valve and install the drain tube onto the 
fi tting.

3.   Un lock drain valve by pushing inward 

slightly and turning counterclockwise.

4.   To open, pull out on the drain valve.
5.   After oil has drained completely, close 

and lock the drain valve by pushing 
inward and turning clock wise until the 
pin is in the locked position as shown.

6.   Remove the drain tube and replace the 

cap onto the end of the drain valve.

7.   Refi ll engine with oil through oil fi ll dipstick 

tube.  Pour slowly.  Do not overfi ll.  For 
approximate capacity see “PRODUCT 
SPEC I FI CA TIONS” section of this man u al.

8.   Use gauge on oil fi ll cap/dipstick for 

checking level.  For accurate reading, 
tighten dipstick cap securely onto the 
tube before removing dipstick.  Keep oil 
at “FULL” line on dipstick. Tighten cap 
onto the tube securely when fi nished.

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 
compressed air to re move dirt and stub-
 born 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 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.

CLEAN AIR INTAKE/COOL ING AREAS

To insure proper cooling, make sure the grass 
screen, cooling fi ns, and other external sur-
faces 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 cool-
ing shrouds. Clean the cooling fi ns and 
external surfaces as necessary. Make sure 
the cooling shrouds are re in stalled.

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.
