ABSTRACT:
A seed corn detasseling apparatus has a mounting base extending across the front of a wheeled vehicle, and three evenly spaced parallelogram linkages are vertically adjustable by separate hydraulic cylinders. A tool bar at the front of each linkage carries two laterally adjustable detasseling heads. Each head consists of a supporting frame the front of which forms an inverted V-shaped guide; and a forwardly and downwardly extending guide frame on the supporting frame cooperates with the inverted V-guide to guide upper leaves and tassels of corn plants between a pair of positively driven longitudinal rollers which are slightly spaced at the front and converge toward the rear. The rollers have short lands and grooves, with the grooves of one roller confronting the lands of the other roller. Tassels are pulled with practically no permanent damage to the upper leaves.
