MAINTENANCE

FIG. 8

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 checked and ad just ed. (See

“TO CHECK BRAKE” in the Ser vice and Ad just ments sec-

tion of this manual).
TIRES

• Maintain proper air pressure in all tires (See side of

tire for proper PSI).

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 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 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 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.

TO SHARPEN BLADE (See Fig. 9)

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 file 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.
