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 checked and ad just ed. (See
“TO ADJUST BRAKE” in the Ser
vice and Ad just ments
section of this manual).
TIRES
• Maintain proper air pressure in all tires (See “PROD UCT
SPEC I FI CA TIONS” 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 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 (See Fig. 19)
For best results mower blades must be kept sharp. Re place
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
and void your warranty.
