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 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 performing any main-
 te nance.

BRAKE OPERATION

If tractor requires more than six (6) feet stopping distance 
at high speed in highest gear, then brake must be adjusted. 
(See “TO ADJUST BRAKE” in the Service and Ad just ments 
section of this manual).

TIRES

•         Maintain proper air pressure in all tires (See “PROD UCT 

SPECIFICATIONS” 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 prevent fl at tires due to 

slow leaks, tire sealant may be purchased from your local 
parts dealer. Tire sealant also prevents tire dry rot and 
corrosion.

OPERATOR PRESENCE SYSTEM

Be sure operator presence and interlock 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 clutch/brake 

pedal is fully depressed and attachement clutch control 
is in the disengaged position.

•         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.

BLADE CARE

For best results mower blades must be kept sharp.  Re place 
bent or damaged blades.
