Abstract
A crop height sensing assembly for use in a control system that automatically adjusts the depth or vertical elevation of a mechanical corn detasseling device in response to the height of a corn plant having a tassel with adjacent leaf portions. The detasseling device is adjustably carried on a portable frame for movement along a corn plant row, and the control system includes a hydraulic cylinder assembly for raising and lowering the detasseling device, and circuitry for actuating the cylinder assembly. The crop sensing assembly includes a rock shaft extended tranversely of the portable frame, a support for the sensing assembly carried on the frame forwardly of the detasseling device for movement therewith, a plurality of dependent sensor rods axially spaced on the rock shaft and rockable therewith in response to contact with the corn plant leaf portions, and a signal assembly responsive to the rockable movement of the shaft to produce a sensing signal for operating the actuating circuitry.
