AUTOMATIC CONTROL INITIATION FOR A HARVESTER

摘要

A harvester with a control system responsive to at least one crop processi ng variable for automatically controlling forward speed of the harvester includ es a crop presence responsive switch connected to an automatic harvester control syste m. The switch, preferably a proximity switch responsive to movement of the feed er 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 operati on resulting from delayed control initiation. The switch is part of an adjustab le down stop mechanism for the feeder house drum.
