Abstract

Abstract An improved corn detasseler head unit for mounting on a corn detasseling machine. The head unit includes an open sided conduit or channel for bending and aligning cornstalks with tassels thereon. Cutter blades are disposed at one end of the conduit to sever the tassel from the cornstalks as they pass through the conduit. The improvement comprises a plurality of guide members positioned in the bottom open side of the conduit to guide the cornstalks toward the cutter blades while preventing leaves on the cornstalk from being cut by the cutter blades.
