TO CHECK BRAKE 
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 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.
