TRACTOR
Always observe safety rules when performing any main-
te nance.
BRAKE OPERATION
If tractor requires more than six (6) feet stopping distance
at high speed in highest gear, then brake must be adjusted.
(See "TO ADJUST BRAKE" in the Service and Ad just ments
section of this manual).
TIRES
Maintain proper air pressure in all tires (See "PROD UCT
SPECIFICATIONS" section of this man ual).
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 prevent fl at 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 sys tems are work-
ing 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 attachement clutch control is in
the disengaged position.
When the engine is running, any attempt by the op er a tor
to leave the seat without fi rst setting the parking brake
should shut off the engine.
When the engine is running and the at tach ment 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.

FLAT WASHER
LOCK WASHER
TO SHARPEN BLADE (See Fig. 12)
NOTE: We do not recommend sharp en ing 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.
NOTE: Do not use a nail for balancing blade. The lobes of
the center hole may appear to be centered, but are not.
BATTERY
Your tractor has a battery charging system which is suf fi cient
for normal use. However, periodic charging of the battery
with an automotive charger will extend its life.
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.

The blade can be sharpened with a fi le 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.)
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.
