TRACTOR
Always observe safety rules when
performing any maintenance.
BRAKE OPERATION
Iftrector requires more than six (6) feet
stopping distance at high speed in
highest gear, then brake must be ad-
justed. (See "TO ADJUST BRAKE" in the
Service and Adjustments section of this
manual).
TIRES
• Maintain proper air pressure in all tires
(See "PRODUCT SPECIFICATIONS"
section of this manual).
• 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
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
tractor does not function as described,
repair the problem immediately.
• The engine should not start unless the
brake pedal is fully depressed and
attachment clutchcontrol 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 reave the
seat should shut off the engine.
• The attachment clutch should never
operate unless the operator is in the
seat.

center hole in blade must alignwith star

TO SHARPEN BLADE
NOTE: We do not recommend sharpen-
ing 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 grindingwheel. 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 bal-
ancer, follow the instructionssupplied
with balancer,)
NOTE: Do not use a nail for balancing
blade. The lobes ofthe center hole may
appear to be centered, but are not.
• Slide blade on to an unthreaded
portionof 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.
BLADE CARE
For best results mower blades must be
keptsharp. Replace bent or damaged
blades.
BLADE REMOVAL
1. Raise mower to highest positionto
allow access to blades,
2. Remove hex bolt, lock washer and fiat
washer securing blade.
3. Install new or resharpened blade with
trailing edge up towards deck as
shown.

BATTERY
Your tractor has a battery charging system
which is sufficient for normal use. How-

an automotive charger will extend its life.
