BATTERY
Your tractor has a battery charging system which is suffi-
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 (See "CONNECT BAT-
TERY" in tl,e Assembly section of this manual).
,, Recharge at 6-10 amperes for 1 hour.
TO CLEAN BATTERY AND TERMINALS
Corrosion and dirt on the battery and terminals can cause
the battery to "leak" power.
, Remove terminal guard.
= Disconnect BLACK battery cable first then RED bat-
tery cable and remove battery from tractor.
,, Wash battery with solution of four tablespoons of
baking soda to one gallon of water. Be careful not to get
the soda solution into the ceils.
= 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 section of this manual).

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 oi!.
Change the oil after the first two hours of operation and
every 50 hours thereafter 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. 15)
Determine temperature range expected before oil change,
All oi! must meet API service classification SF or SG,
Be sure tractor is on level surface.
, Oil will drain more freely when warm.
Catch oil in a suitable container.
Remove oil fil! cap/dipstick. Be careful not to allow dirt
to enter the engine when changing ol,
. Remove drain plug.
= After oil has drained completely, replace oil drain plug
and tighten securely.
= Refill engine with oil through oil fill dipstick tube. Pour
slowly, Do not overfill. For approximate capacity see
"PRODUCT SPECIFICATIONS" on page 3 of this
manual.
Use gauge on oil fill cap/dipstick for checking level. Be
sure dipstick is in all the way for accurate reading.
Keep oil at "FULL" line on dipstick.
