An agricultural combine having a supporting structure that is driven by ground engaging wheels at a harvesting speed by a propulsion assembly. The combine is also provided with a threshing assembly that is driven by a variable torque sensing drive. The variable torque sensing drive is manipulated by pressurized hydraulic fluid. A hydraulic sensor in hydraulic communication with the variable torque sensing drive provides an actual hydraulic pressure signal that is directed to an electronic controller. An operator control in the operator's cab 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 hydraulic pressure signal. The electronic controller regulates the forward speed (harvesting speed) of the combine so that the desired hydraulic pressure signal is equal to the actual pressure signal. The harvesting speed regulation can be modified or overridden by moisture signals from a moisture sensor located in the feederhouse for sensing the moisture content of harvested crop.
An agricultural combine for harvesting, threshing and separating an agricultural crop, the agricultural combine having a loss rate, the agricultural combine comprising:
A method of controlling the harvesting speed of an agricultural combine having a variable torque sensing drive for driving a threshing assembly, the method comprising:
An agricultural combine for harvesting, threshing and separating an agricultural crop, the agricultural combine comprising:
