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 fi rst 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 fi ve (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 fl at 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 function 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 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.

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 en-
gaged, any attempt by the operator to shift into reverse
should NOT shut off the engine.

BLADE CARE

For best results mower blades must be sharp. Re place
worn, bent or damaged blades.

CAUTION:

Use only a replacement blade

approved by the manufacturer of your
tractor. Using a blade not approved
by the manufacturer of your tractor is
hazardous, could damage your tractor
