MAINTENANCE

FIG. 9

TO SHARPEN BLADE (See Fig. 10)

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.
• 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.)

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.

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

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.
