BATTERY
Your tractor
has a battery
charging
system
which is sufficient
for normal
use.
However,
periodic
charging
of the battery
with an au-
tomotive
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 termi-
nals can cause
the battery
to "leak"
power.
1.
Disconnect
BLACK
battery
cable
first
then
RED
battery
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 petroleum
jelly.
5.
Reinstall
battery
(See
"REPLACING
BATTERY"
in the SERVICE
AND
AD-
JUSTMENTS
section
of this manual).
TRANSAXLE
COOMNG
Keep transaxle
free from build-up
of dirt and
chaff which
can restrict
cooling.
V=BELTS
Check V-belts for deterioration
and wear after
100 hours
of operation
and replace
if neces-
sary. The belts are not adjustable.
Replace
belts if they begin
to slip from wear.
ENGINE

NOTE:
Although
multi-viscosity
oils (5W30,
10W30
etc.) improve
starting
in cold weather,
the oils will result in increased
oil consumption
when
used above
32°E
Check
your engine
oil level
more
frequently
to avoid
possible
engine
damage
from
running
low on oil.
Change
the oil after every 50 hours of opera-
tion 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
se-
curely
each time you check
the oil level.
TO CHANGE
ENGINE
OIL
Determine
temperature
range
expected
before
oil change.
All oil must
meet

,
Oil will drain more freely
when
warm.
• Catch
