TRACTOR

Always observe safety rules when per form ing any 

main te nance.

BRAKE OPERATION

If tractor requires more than five (5) feet (1,5 m) 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 

section of this manual.)

TIRES

• 

Maintain proper air pressure in all tires.  (See the sides 

of tires 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 

OPERATION SYSTEM (ROS) (See Fig. 16)

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 

engaged, 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.

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 first  then RED  bat tery 

cable and remove battery from tractor.

•  Rinse the battery with plain water and dry.
• 

Clean terminals and battery cable ends with wire brush 

until bright.

•  Coat terminals with grease or petroleum jelly.
• 

Reinstall battery. (See “REPLACING BATTERY" in the 

Service and Adjustments section of this manual.)

BLADE REMOVAL (See Fig. 17)

•  Raise mower to highest position to allow access to 

blades.

NOTE: 

Protect your hands with gloves and/or wrap blade 

with heavy cloth.
•  Remove blade bolt by turning counterclockwise.
• 

Install new or resharpened blade with stamped "GRASS 

SIDE" facing the ground.

IMPORTANT:

 To ensure proper assembly, center hole in 

blade must align with star on mandrel assembly.
•  Install and tighten blade bolt securely (45-55 Ft. Lbs./ 

62-75 Nm).
