ABSTRACT:
Corn detasseling apparatus and method are disclosed whereby tassels are quickly and cleanly separated from corn plants while preventing damage to the leaves and the remainder of the stalk. The apparatus includes a detasseling head having two opposed rollers with alternating ridges and grooves which extend longitudinally with respect to the rotational axis of the rollers. The ridges and grooves of each roller intermesh with those of the opposing roller to form a wavy nip, and during rotation of the rollers, the tassels are securely grasped by the nip and pulled off the plants. In addition, the ridged rollers function as impellers which create forceful air currents that flow downward and blow the leaves of the plants away from the nip. Accordingly, the tassels are removed from the plant without any rough handling or damaging of the leaves, and with minimal cutting or shredding of the tassels to form objectionable trash.
