TO SHARPEN
BLADE
NOTE:
We do not recommend
sharp-
ening blade - but if you do, be sure the
blade is balanced.
Care should be taken to keep the blade
balanced.
An unbalanced
blade will cause
excessive vibration and eventual damage
to mower and engine.
• The blade can be sharpened
with a file
or on a grinding wheel.
Do not attempt
to sharpen while on the mower.
• To check blade balance, you will need a
5/8" diameter steel bolt, pin, or a cone
balancer.
(When using a cone balancer,
follow the instructions supplied with
balancer.)
NOTE:
Do not use a nail for balancing
blade.
The lobes of the center hole may
appear to be centered, but are not.
• Slide blade on to an unthreaded
portion
of the steel bolt or pin and hold the
bolt or pin parallel with the ground.
If
blade is balanced,
it should remain in a
horizontal
position.
If either end of the
blade moves downward,
sharpen the
heavy end until the blade is balanced.

BATTERY
Your tractor
has a battery
charging
system
which
is sufficient
for normal
use.
How-
ever, 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 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
terminals
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 petro-
leum jelly.
5.
Reinstall
battery
(See "REPLACING
BATTERY"
in the Service
and Adjust-
ments
section
of this manual).
TRANSAXLE
COOLING
The transmission
fan and cooling
fins
should
be kept clean
to assure
proper
cooling.
Do not attempt
to clean fan or transmis-
sion while
engine
is running
or while the
transmission
is hot. To prevent
possible
damage
to seals,
do not use high pressure
water
or steam
to clean
transaxle.
• Inspect
cooling
fan to be sure fan blades
are intact
and clean.
• Inspect
cooling
fins for dirt, grass
clip-
pings
and other
materials.
To prevent
damage
to seals,
do not use com-
pressed
air or high pressure
sprayer
to
clean
cooling
fins.
TRANSAXLE
PUMP
FLUID
The transaxle
was sealed
at the factory
and fluid maintenance
is not required
for
the life of the transaxle.
Should
the trans-
axle ever leak or require
servicing,
contact
a Sears
or other
qualified
service
center.
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.
ENGINE
LUBRICATION
Only use high quality detergent
oil rated
with API service classification
SG-SL
Se-
lect 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.
