Further disclosed is a combined harvester, which includes the threshing device with two-way pull wires and adjustable threshing clearance.

A control system for controlling a motion of an auger tube of a combine harvester comprises a dynamic pre-filter, a position controller, and a speed controller. The dynamic pre-filter receives a desired position value for the auger tube and generates a filtered desired position signal which changes the desired position value from an old value to a new value over a time period. The position controller receives a first difference between the filtered desired position signal and an actual position of the auger tube. The position controller generates a desired angular speed signal that varies according to the first difference. The speed controller receives a second difference between the desired angular speed signal and an actual speed of the auger tube. The speed controller generates an actuator signal that varies according to the second difference and is received by an actuating system that moves the auger tube.

A system for monitoring a condition of a sickle of a header of an agricultural machine. The system includes a knife guard mounted to the header, a knife section of the sickle that is configured to move either along or with respect to a surface of the knife guard, and a sensor either mounted to the knife guard or another surface of the header for sensing the condition of the knife section.

Feederhouse gearboxes are provided for installation on combine harvesters. In embodiments, the feederhouse gearbox includes a gearbox housing, an output shaft rotatable about an output axis, and a primary drive input. The primary drive input is mechanically linked to an engine of the combine harvester when the feederhouse gearbox is installed thereon. A reverser drive input is mechanically linked to a reverser motor of the combine harvester when the feederhouse gearbox is installed on the combine harvester. The feederhouse gearbox further includes a selector mechanism within the gearbox housing and movable between a primary drive position and a reverser drive position, a primary gear train transmitting rotation from the primary drive input to the output shaft when the selector mechanism is in the primary drive position, and a reverser worm drive transmitting rotation from the reverser drive input to the output shaft when the selector mechanism is in the reverser drive position.

An agricultural work machine is provided comprising a surroundings detection device for detecting a surroundings in sections, and one or more controllable working elements, wherein the surroundings detection device generates surroundings detection signals, which can be processed in a control and regulating device assigned to the agricultural work machine, wherein the surroundings detection device is designed as a scanner, which scans the surroundings in scanning planes, and wherein each scanning plane is assigned to the control of working elements.

A method for calibrating a height control system for an implement of an agricultural work vehicle can include providing an input signal to the height control system to adjust a height of the implement relative to the ground surface; monitoring the height of the implement relative to the ground surface; adjusting at least one gain of the height control system; and determining a maximum stability gain of the height control system based on the at least one gain and the monitored height. The maximum stability gain can correspond with a stability point of the height control system at which the height control system transitions from stable to unstable. The method can include setting gain(s) of the height control system based on the maximum stability gain.

A method begins by a computing device allocating a plurality of tasks of an agricultural prescription for a farming geographic area to a fleet of farming equipment. While executing tasks of the plurality of tasks, the method continues with at least some of the fleet of farming equipment collecting task execution data. Based on the task execution data, the method continues with the computing device updating at least one of the agricultural prescription, the plurality of tasks, and the allocation of at least one task of the plurality of tasks.

An automatic driving system for grain processing, an automatic driving method, and an automatic identification method is illustrated. The automatic driving system includes a grain processing host, an image acquiring device, and an image processing system. The image acquiring device is provided in the grain processing host. The image acquiring device acquires at least one image around the grain processing host. The image processing system identifies areas in the image by utilizing an image segmentation and identification technique on the basis of the image acquired by the image acquiring device. The grain processing host automatedly controls driving based on the areas identified by the image processing system.

An intelligent harvester with instantaneous stop functions includes a harvester body, a detecting system for detecting a human body within an area range on a traveling route of the harvester body, and a brake system arranged on the harvester body and operatively connected to the detecting system. When the detecting system detects a human body present within the area range on a traveling path of the harvester body, the brake system controls the harvester body to brake.
