ABSTRACT:
A harvester has an apron on whose leading edge is provided a sickle bar. Immediately behind and parallel to this sickle bar there is provided a flexible tube having at its front edge a lip connected to the apron and at its rear edge a lip connected to a horizontally extending throw-off member. Inside the tube there is provided a pair of parallel metal strips which on, compression of the tube, close a circuit that generates a signal. This signal may be employed to warn the operator that a rock rests on the apron or may serve to stop the mower and/or reverse the crop feeder. In addition an automatic flipper is provided to pivot the throw-off member secured to the rear lip of the tube so as to automatically to flip the picked-up foreign body off the apron.
