which is sufficient for normal use. However,
periodic charging of the battery with an au-
tomotive charger wilt 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.

Corrosion and dirt onthe battery and terminals
can cause the battery to "leak" power.
1. Disconnect BLACK battery cable first
then RED battery cable and remove
battery from tractor.

with API service classification SG-SL.
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, they will result in increased
oil consumption when used above 32°R
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 fill cap/
dipstick securely each time you check the
oil level.

before oil change. All oil must meet API
service classification SG-SL.
Be sure tractor is on level surface.
