BATTERY
Your tractor has a battery charging system which is suffi-
cient for normal use.
However, pedodic charging of the
battery with an automotive charger will extend its life.
Keep battery and terminals dean,
Keep battery botts tight,
Keep small vent holes open (See "CONNECT
BAT-
TERY" in the Assembty section of this manual).
Recharge at 6-10 amperes for I hour,
TO CLEAN BATTERY AND TERMINALS
Corrosion and dirt on the battery and terminals can cause
the battery to "leak" power.
Open battery box door.
Disconnect BLACK batter,/cabie
first then RED bat-
tery cable and remove battery from tractor.
Wash
batten! with solution of four tablespoons
of
baking soda to one gallon of water. Be careful not to get
the soda solution into the ceils.

V-BELTS
Check V-belts for deterio ration and wear after 100 hours of
operation
and replace if necessary.
The botts are not
adjustable,
Replace belts if they begin to slip from wear.
NOTE: Although multFviscosity
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 the first two hours of operation and
every 25 hours thereafter 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.
