1. A corn detasseling apparatus, comprising:
a chassis;
a head, the head having a toolbar mounted on a toolbar supporting linkage to adjust a height of the toolbar, the toolbar supporting a plurality of row units, each of the row units comprising:
a framework supporting a cross-member;
two pullers or cutters supported on the cross-member;
a height adjustment assembly comprising a telescoping assembly mounted on the framework cross-member for independently adjusting vertical position of the row unit to maintain the pullers or cutters at a predetermined height relative to corn plants being engaged;
an optical sensing assembly associated with the row unit for sensing a top of corn plants; the optical sensing assembly comprising:
an upper first photoelectric sensor sensing presence of a corn plant at a height of the first photoelectric sensor;
a lower second photoelectric sensor sensing presence of a corn plant at a height of the second photoelectric sensor, the height of the first photoelectric sensor being above the height of the second photoelectric sensor;
a processor for receiving and storing detasseling data from the first photoelectric sensor and from the second photoelectric sensor and controlling the height adjustment assembly.
