any maintenance.
BRAKE
OPERATION
If tractor
requires
more than five (5) feet to
stop at highest
speed
in highest
gear on a
level,
dry concrete
or paved
surface,
then
brake
must be checked
and adjusted.
(See

TIRES
• Maintain
proper
air pressure
in all tires
(See the side of the tire for proper
PSI).
,
Keep tires free of gasoline,
oil, or insect
control
chemicals
which can harm rubber.
, Avoid
stumps,
stones,
deep
ruts, sharp
objects
and other hazards
that may cause
tire damage.
NOTE:
To seal tire punctures
and prevent
fiat
tires due to slow leaks, tire sealant may be pur-
chased from your local parts dealer. Tire seal-
ant also prevents
tire dry rot and corrosion.

NOTE:
We do not recommend
sharpening
blade
- but if you
do, be sure
the blade
is
balanced.

should
be taken
to keep
the

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 bal-
ancer.
(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.
