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:
• Park tractor on a level, dry concrete or paved sur-
face, depress brake pedal all the way down and
engage parking brake.
• Disengage transmission by placing freewheel con-
trol in “transmission disengaged” position. Pull
freewheel control out and into the slot and release
