Adjustments section of this manual).
TIRES
• Maintain proper air pressure in all tires
(See =PRODUCT SPECIFICATIONS"
on page 5 of this manual).
• Keep tires free of gasoline, oil, or insect
control chemicals which can harm rub-
ber.
• Avoid stumps, stones, deep ruts, sharp
objects and other hazards that may
cause tire damage.
NOTE: To seal tire punctures and prevent
flat tires due to slow leaks, tire sealant
may be purchased from your local parts
dealer. Tire sealant also prevents tire dry
rot and corrosion.
OPERATOR PRESENCE SYSTEM
Be sure operator presence and interlock
systems are working properly. If your trac-
tor does not function as described below,
repair the problem immediately.
• The engine should not start unless the
clutch/brake pedal is fully depressed
and attachment clutch control is in the
disengaged position.
• When the engine is running, any
attempt by the operator to leave the
seat without first setting the parking
brake should shut off the engine.
• When the engine is running and the
attachment clutch is engaged, any
attempt by the operator to leave the
seat should shut off the engine.
• The attachment clutch should never
operate unless the operator is in the
seat.
IMPORTANT: To ensure proper assembly,
center hole in blade must align with star
on mandrel assembly.
• Reassemble hex bolt, lock washer and
flat washer in exact order as shown.
• Tighten bolt securely (27-35 Ft. Lbs.
torque).
IMPORTANT: Blade bolt is Grade 8 heat
treated.

TO SHARPEN BLADE
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 unbalanced blade
will cause excessive vibration and even-
tual damage to mower and engine.
° The blade can be sharpened with a file
or on a grinding wheel. Do not attempt
to sharpen while it is 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-
ancer).
° Slide blade onto 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 hori-
zontal position. If either end of the blade
moves downward, sharpen the heavy
end until the blade is balanced.
NOTE: Do not use a nail for balancing
blade. The lobes of the center hole may
appear to be centered, but are not.
BLADE CARE
For best results mower blades must be
kept sharp. Replace bent or damaged
blades.
BLADE REMOVAL
• Raise mower to highest position to allow
access to blades.
• Remove hex bolt, lock washer and fiat
washer, securing blade.
• Install new or resharpened blade with
