Abstract:
A harvester having a frame supported on the surface of the ground by wheel structure for forward movement through a field of standing crop, the harvester including crop processing structure and a header for directing the crop to the processing structure, a header control system for adjusting the header vertically, wherein rate of material flow to the processing structure from the header is dependent on header vertical adjustment and forward speed, a harvesting control comprising:a harvester speed control for controlling forward speed of the harvester through the field, transducer structure for providing a header position signal; a throughput transducer located in the processing structure for providing a throughput signal; and wherein the harvester speed control is responsive to a header position signal to immediately decrease the forward speed of the harvester prior to the throughput signal changing as a result of header position change when the header position signal indicates a lowering of the header, thereby reducing sudden increases in the rate of material flow to the processing structure resulting from changes in the vertical adjustment of the header.
