TRACTOR
Always observe safety rules when per form ing any main-
te nance.
BRAKE OPERATION
If tractor requires more than five (5) feet to stop at highest
speed in high est gear on a level, dry concrete or paved
surface, then brake must be checked and ad just ed. (See
"TO ADJUST BRAKE" in the Ser vice and Ad just ments
section of this manual).
TIRES
•
Maintain proper air pressure in all tires (See the side
of the tire).
•
Keep tires free of gasoline, oil, or insect control chemi-
cals 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 pre vent flat tires due
to slow leaks, tire sealant may be purchased from your
local parts dealer. Tire sealant also pre vents tire dry rot
and corrosion.

ERATION SYSTEM (ROS)

are work ing properly. If your tractor does not function as
described, repair the problem immediately.

The attachment clutch should never operate unless
the operator is in the seat.
CHECK REVERSE OPERATION (ROS) SYSTEM

TO SHARPEN BLADE (See Fig. 11)
NOTE: We do not recommend sharpening blade - but if
you do, be sure the blade is balanced.
Care should be taken to keep the blade balanced. An un-
balanced blade will cause excessive vibration and even tual
damage to mower and engine.
•
The blade can be sharpened with a file or on a grind-
ing 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
bal anc er).
NOTE: Do not use a nail for balancing blade. The lobes of
the center hole may appear to be centered, but are not.
