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 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 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.

OPERATION SYSTEM (ROS) (See Fig.19)

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

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
