Abstract

A crop pick-up header (2) according to the invention comprises a frame (10) and a rotatable reel (13) configured to collect crops from the ground, as well as a rotatable auger (20) provided with two oppositely wound helicoidal flights (26). The auger is rotatable about its central axis with respect to a pair of support arms (21) which are themselves pivotable relative to the frame, so that the pivoting movement of the arms results in lowering or raising the auger. The height position of the auger (20) is a function of the crop throughput and of the auger's rotational speed. The header of the invention is equipped with at least one sensor (30) configured to measure the height position of the auger or a parameter representative thereof. The header comprises or is coupled to a control unit (31) configured to control the auger's rotational speed as a function of the detected height position, determined through the sensor (30). In particular, the auger speed is lowered when the auger drops below a predefined height, so that lower throughput is compensated by a lower auger speed, thereby ensuring efficient chopping in a harvester to which the header is coupled, even when the crop yield drops below a given level.
