BATFERY
Your tractor
has a battery
charging
system
which is sufficient
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 I 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.
• Remove
terminal
guard.
• Disconnect
BLACK
battery
cable first
then RED
battery
cable and removu
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 petro-
leum jelly.
• Reinstall
battery
(See "REPLACING
BATTERY"
in the SERVICE
AND
ADJUSTMENTS
section
of this
manual).
V-BELTS
Check
V-belts for deterioration
and wear
after 100 hours of operation
and replace
if necessary.
The belts are not adjustable.
Replace
belts if they begin to slip from
wear.
TRANSAXLE
COOLING
Keep transaxle
free from build-up
of dirt
and chaff which can restrict cooling.
ENGINE
LU BRICATION
Only use high quality
detergent
oil rated
with API service
classification
SF, SG, or
SH. Select the oil's SAE viscosity
grade
according
to your expected
operating
temperature.
SAE VISCOSITY
GRADES
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 50 hours of
operation
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
Determine
temperature
range expected
before
oil change.
All oil must meet API
service
classification
SF, SG or SH.
Be sure tractor is on level surface.
• Oil will drain more freely when warm.
• Catch
oil in a suitable
container.
• Remove
oil fill cap/dipstick.
Be careful
not to allow dirt to enter the engine
when
changing
oil,
• 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.

on oil fill cap/dipstick
for
checking
level.
Be sure dipstick
cap is
tightened
securely
for accurate
reading.
Keep oil at "FULL"
line on
dipstick.
Air Screen,
Oil Fill Cap/
Dipstick
Oil Drain Plug
