A harvester with a control system responsive to at least one crop processing variable for automatically controlling forward speed of the harvester includes a crop presence responsive switch connected to an automatic harvester control system. The switch, preferably a proximity switch responsive to movement of the feeder house drum from an empty feeder house limit position, provides a signal in response to crop entering the feeder house for initiating the automatic speed control of the harvester after the header receives the crop and prior to the crop entering the processing structure. The automatic control initiation structure is particularly useful with an automatic combine throughput control and eliminates unstable operation resulting from delayed control initiation. The switch is part of an adjustable down stop mechanism for the feeder house drum.
A harvester supported for forward movement over a field of crop to be harvested having processing structure located on the harvester, a feeder house including a housing and a drum for moving the crop to the processing structure, the harvester including a control system responsive to a crop processing variable for automatically controlling the harvester, and switch structure responsive to presence of crop in the feeder house and connected to the control system for initiating the automatic control of the harvester.
A harvester supported for forward movement over a field of crop to be harvested, processing structure located on the harvester, a header for receiving the crop, a feeder house including a housing for receiving the crop from the header and directing the received crop to the processing structure, the harvester including a control system responsive to at least one crop processing variable for automatically controlling forward speed of the harvester, and crop presence responsive structure connected to the control system and providing a signal in response to crop in the feeder house for initiating the automatic control of the harvester after the header receives the crop and prior to the crop entering the processing structure.
A method of initiating automatic control of a combine having a header, crop processing structure, a feeder house for moving the crop from the header to the processing structure, and a control system responsive to a crop processing variable for automatically controlling movement of the header relative to the crop in a field, the method of initiating including the steps of:
