CUSTOMER RESPONSIBILITIES
TRACTOR
Always observe safety rules when performing any mainte-
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 Adjust-
ments section of this manual).
TIRES
Maintain proper air pressure in all tires (See PROD-
UCT 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 attachement 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.
BLADE CARE
For best results mower blades must be kept sharp. Replace
bent or damaged blades.

blades.

BATTERY
Your tractor has a battery charging system which is suffi-
cient for normal use. However, periodic charging of the
battery with an automotive charger will extend its life.
Keep battery and terminals clean.
Keep battery bolts tight.
Keep small vent holes open.
Recharge at 6-10 amperes for 1 hour.
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 neces-
sary.
TO CLEAN BATTERY AND TERMINALS
Corrosion and dirt on the battery and terminals can cause the
battery to leak power.
Remove terminal guard.
Disconnect BLACK battery cable first then RED battery
cable and remove battery from tractor.
Rinse the battery with plain water and dry.
Clean terminals and battery cable ends with wire brush
until bright.
Coat terminals with grease or petroleum jelly.
Reinstall battery (See REPLACING BATTERY" in the
SERVICE AND ADJUSTMENTS section of this manual).

TO SHARPEN BLADE (See Fig. 14)
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 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 balancer.)
NOTE: Do not use a nail for balancing blade. The lobes of
the center hole may appear to be centered, but are not.
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.
