More Information
Summary:An operator control in the operator's cab (35) of the combine provides a loss rate signal that is also directed to the electronic controller. The electronic controller converts the loss rate signal into a desired feeder-house force signal. The controller regulates the forward speed (harvesting speed) of the combine so that the desired feeder-house force signal is equal to the actual feeder-house force signal. The harvesting speed regulation can be modified or overridden by moisture signals from a moisture sensor located in the feeder-house for sensing the moisture content of harvested crop. The agricultural combine (10) has a supporting structure (12) that is driven by ground engaging wheels (14) at a harvesting speed by a propulsion assembly. The combine is also provided with crop processing assemblies for processing a harvested crop. A feeder-house (18) directs the harvested crop material to the crop processing assemblies. A feeder-house force sensor senses the force exerted by the harvested crop material as it passes through the feeder-house. The feeder-house force signal is directly related to crop throughput.
