A compact belt tensioner to be installed in draper harvesting headers that accommodates the flexing and twisting of the conveyor belts and generates a constant tension evenly distributed across the width of the conveyor belts. The tensioner performs an automatic belt tension without the operators intervention.

An agricultural vehicle includes a chassis (16), a lift arm (18) movably coupled to the chassis (16), a lift actuator (21) coupled to the lift arm (18), a header (14) coupled to the lift arm (18), and a controller (120) operably coupled to the lift actuator (21). The controller (120) is configured to: receive a header type signal corresponding to a header type of the header; define a lift height limit of the header based at least partially on the received header type signal, the lift height limit being a first height limit when a first header type signal is received or a second height limit when a second header type signal is received; and output a lift signal to the lift actuator (21) to vertically displace the header (14). Header vertical displacement is limited to the first height limit if the first header type signal is received or the second height limit if the second header type signal is received.

Method and apparatus for controlling the height of a header for use with an agricultural harvester. The header height is controlled by receiving orientation values from a first set of sensors representing orientation of respective support arms of the header, receiving height values from a second set of sensors representing height of the respective support arms with respect to ground, combining the height values and orientation values for each support arm to create a respective multi-sensor value, and controlling the position of the header with respect to the agricultural harvester responsive the multi-sensor value.

A system for controlling harvesting implement position of an agricultural harvester includes a harvesting implement configured to be coupled to the harvester to permit adjustment of a current position of the implement relative to a field surface. Additionally, the system includes a sensor configured to capture data indicative of the current position of the implement relative to the field surface, a display device, and a controller communicatively coupled to the sensor and the display device. As such, the controller is configured to monitor the current position of the implement based on the data captured by the sensor. Furthermore, the controller is further configured to initiate display of a graphical user interface on the display device, with the graphical user interface displaying a first interface element associated with the current position of the implement relative to a second interface element associated with a reference position of the implement.

A hydraulic system for use with an agricultural harvester header is provided. The hydraulic system includes a reversible hydraulic pump that drives a reversible hydraulic motor in a forward or harvesting direction and a reverse or header cleaning direction. The system can further include a second reversible pump similarly driving a second reversible hydraulic motor in forward and reverse directions. The pumps and motors can be used to operate various header implements, e.g., the first pump and motor may be used to operate at least a crop cutting knife and the second pump and motor can be used to operate at least one conveyor. The pumps and motors operate within hydraulic circuits which share their hydraulic fluid with the harvester's hydraulic fluid reservoir, thereby reducing system weight, complexity and maintenance requirements.

In accordance with an example embodiment, an agricultural vehicle may include first and second harvesting devices connected to the agricultural vehicle. The agricultural vehicle may include a sensor which detects whether the agricultural vehicle is traveling in an operational or non-operational direction. The agricultural vehicle may include a lift controller in communication with the sensor and the first and second harvesting devices. The lift controller may automatically reposition the first and second harvesting devices into non-operating positions when the lift controller determines an intention to move the agricultural vehicle in a non-operational direction.

A header of an agricultural harvester for the transport of a flow of crop from a header to a combine feeder house. The header includes a frame having a floor, a conveyor assembly, and a drive mechanism. The conveyor assembly is mounted above the floor to urge a flow of crop material during harvesting operations, and the drive mechanism operatively connects to the conveyor assembly to drive movement of the conveyor assembly. The drive mechanism includes a drive motor mounted to the frame beneath the floor about a medial section of the header.

An agricultural harvester includes a chassis, a header for cutting and gathering crop material, the header being carried by the chassis, and an auger. The auger moves the cut crop material toward a central area of the header. The auger is rotatably carried by the header. The auger has a plurality of auger sections. The auger includes an auger crankshaft and a hingeable coupling for coupling two of the auger sections to each other. The hingeable coupling allows the auger sections to rotate about differing axes. The hingeable coupling has an internal opening. The auger crankshaft provides positional timing to auger fingers. The auger crankshaft passing through the internal opening.

A drum conveyor has a laterally extending drum (120), first and second stub axles (204, 206) extending into the ends of the drum; two link members (208, 210) that are fixed to the stub axles inside the drum and that support a third axle (212) inside the drum for free rotation with respect to the two link members.

An agricultural harvester includes a chassis; at least one ground engaging traction member held by the chassis; a cutter held by the chassis; a sensor held by the agricultural harvester so that the sensor is directed in front of the cutter and configured to emit and receive sound and/or radio waves and produce a plurality of output signals; and an electrical processing circuit coupled to the sensor. The electrical processing circuit is configured to produce a field map from the plurality of output signals and adjust an operating parameter of the agricultural harvester based on the field map.
