TO CHECK BRAKE 

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 serviced.
You may also check brake by:
1.  Park tractor on a level, dry concrete or paved surface, 

depress brake pedal all the way down and engage 

parking brake.

2.  Disengage transmission by placing freewheel control 

in “transmission disengaged” position. Pull freewheel 

control out and into the slot and release so it is held in 

the disengaged position.

The rear wheels must lock and skid when you try to manually 

push the tractor forward. If the rear wheels rotate, then the 

brake needs to be serviced. Contact a qualified service center.
