Abstract:
An agricultural combine for harvesting, threshing and separating an agricultural crop, the agricultural combine having a loss rate, the agricultural combine comprising:a supporting structure; ground engaging means for propelling the supporting structure at a harvesting speed; a threshing assembly being mounted to the supporting structure; a variable torque sensing drive for driving the threshing assembly, the variable torque sensing drive being provided with hydraulic fluid having a hydraulic pressure; a hydraulic pressure sensor for sensing the hydraulic pressure of the hydraulic fluid and providing an actual hydraulic pressure signal; a controller for adjusting the harvesting speed of the ground engaging means in response to the actual hydraulic pressure sensed by the hydraulic pressure sensor; an operator control for controlling the loss rate of the combine, the operator control providing a loss rate signal to the controller, wherein the controller converts the loss rate signal into a desired hydraulic pressure signal that together with the actual hydraulic pressure signal regulates the harvesting speed of the ground engaging means.
