THE LOWER OR BUTT STOP BELTS ARE FORMED OF BENT SLATS THAT SLOPE INWARD TO COOPERATIVELY FORM A LEDGE OR BUTT STOP FOR ARRESTING DOWNWARD MOVEMENT OF THE EARS TO BE STRIPPED FROM THE STALK. A POWER DRIVEN CUTTER BLADE FOR TRIMMING THE BUTT ENDS OF THE EARS IS MOUNTED BETWEEN THE UPPER AND LOWER PAIRS OF GATHERING AND BUTT STOP BELTS IN THE PATH OF THE LOWER ENDS OF THE UPRIGHT EARS. DOWNSTREAM OF THE BUTT TRIMMING BLADE, EACH EAR STRIKES A FIXED ABUTMENT WHICH ORIENTS THE TRIMMED EAR TO BE DISCHARGED FROM THE MACHINE TASSLE-END FIRST.
