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.
• 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 necessary.
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
bat tery cable and remove battery from tractor.
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 serviced. (See
“TO CHECK BRAKE” in the Ser vice and Ad just ments
section of this manual).
TIRES
• Maintain proper air pressure in all tires (See PSI
on tires).
• 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.
OPERATOR PRESENCE SYS TEM AND REVERSE OP-
ERATION SYSTEM (ROS)
Be sure operator presence and reverse operation sys-
tems are work ing properly. If your tractor does not func-
tion as described, repair the problem immediately.
• The engine should not start unless the brake pedal
is fully de pressed, and the attachment clutch con trol
is in the dis en gaged position.
CHECK OPERATOR PRESENCE SYSTEM
• When the engine is running, any attempt by the
op er a tor to leave the seat without first 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.
CHECK REVERSE OPERATION (ROS) SYSTEM
• When the engine is running with the ignition switch
in the engine "ON" position and the at tach ment
clutch engaged, any attempt by the operator to
shift into reverse should shut off the engine.
• When the engine is running with the ignition switch
in the ROS "ON" position and the at tach ment clutch
engaged, any attempt by the operator to shift into
reverse should NOT shut off the engine.

worn, bent or damaged blades.
