MAINTENANCE

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.   

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

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.

OIL DRAIN VALVE

FIG. 11

•    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.

BATTERY

Your tractor has a battery charging system which is suf fi  cient 
for normal use.  However, periodic charging of the battery 
with an automotive charger will extend its life.
•      Keep battery and terminals clean.
•      Keep battery bolts tight.
•      Keep small vent holes open.
•      Recharge at  6-10 amperes for 1 hour.

NOTE:

 The original equipment battery on your tractor is 

maintenance free. Do not attempt to open or remove caps 
or covers. Adding or checking level of electrolyte is not 
necessary.

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  “REPLACING  BATTERY”  in 

the SERVICE AND ADJUSTMENTS section of this 
man u al).
