Abstract: An agricultural harvesting machine having a cutting unit for cutting harvested material and a driver assistance system is disclosed. The driver assistance system includes a memory in which control strategies for the operation of the cutting unit are stored and a computing device for controlling a cutting angle of the cutting unit in accordance with the control strategies. The computing device is configured to link first and second control strategy to one another via a weighting variable, with the weighting variable being adjustable by a driver. The driver assistance system uses at least one of the control strategies and sensed forefield information to automatically determine the cutting angle of the cutting unit and to automatically control the cutting unit based on the determined cutting angle.

Abstract: A cutting unit (1) that has a cutter bar (6) that is operated rigidly or flexibly, depending on the harvest conditions, which can be operated in at least two different operating modes, wherein the cutting unit (1) includes a first sensor assembly (1) disposed on the cutting unit (1) that can be deactivated, which is for operating the cutting unit (1) in a first operating mode, and a second sensor assembly (17) for operating the cutting unit (1) in a second operating mode, wherein, when switching between the at least two operating states, the first sensor assembly (13) or the second sensor assembly (17) is activated without interruption in operation, to execute a distance determination, depending on the selected operating mode.

Abstract: The present invention relates to a method for operating an attachment arranged on a pick-up apparatus of a self-propelled combine harvester, wherein the attachment comprises a central portion and two side portions which are each connected to the central portion by a frame joint so as to be pivotable about a pivot axis oriented in the direction of travel, wherein the respective side portion is pivotable about the pivot axis transversely to the direction of travel relative to the central portion by means of an actuator that is activated by a control apparatus, wherein a vertical distance of the attachment from the ground is adaptively set by at least one hydraulic cylinder on the pick-up apparatus, wherein, for the ground guidance of the attachment, the positioning of the side portions relative to the central portion is controlled or regulated independently of vertical and transverse guidance, activated by the combine harvester, of the attachment.

Abstract: A self-propelled harvester having a height-adjustable pick-up device, on which an attachment pivotable about a virtual pendulum axis of the pick-up device is positioned for picking up harvested material is disclosed. The pick-up device is configured for adaptive adjustment of a vertical distance of the attachment from the ground. Further, at least one support wheel is positioned at least on the outer lateral regions of the attachment. The support wheel may be guided in a height-movable manner by a hydraulic cylinder connected to a hydraulic circuit of a hydraulic system having a pressure source. Position regulation of the attachment transverse to the forward direction of travel by pivoting about the virtual pendulum axis is independent of a transverse guidance of the attachment controlled or regulated by the harvester.

Abstract: An agricultural machine comprises a carrier vehicle and an attachment is disclosed. The attachment is pivotably guided on the carrier vehicle about an axis extending in the direction of travel of the carrier vehicle. To the right and left of the axis, a support wheel is connected to the attachment via a damped, compressible arm. A control circuit is configured to decide whether a pivoting motion of the attachment about the axis is or is not desirable and, in the case that the pivoting motion is desirable, the arm that is compressed by the pivoting motion is switched from a strongly dampened compressible state to a substantially undampened state.

Abstract: A height control system for a front harvesting attachment, comprising a frame, at least one crop pick-up device, and a ground-conforming cutterbar which is situated on a plurality of supporting arms that can pivot about a horizontal axis and are articulated on the frame. The supporting arms can be pivoted, originating from a desired position to be set before the start of a harvesting operation, between an upper end position, which delimits a deflection of the supporting arms in the direction of the crop pick-up device, and a lower end position, wherein the upper end position has a first clearance and the lower end position has a second clearance from the desired position, wherein the desired position can be adapted, during the harvesting operation, to changing harvesting conditions and/or operating conditions depending on a deflection of the cutterbar, in order to minimize the first clearance and maximize the second clearance.

Abstract: A combine harvester includes a belt cutting unit comprising a center belt for conveying harvest to an intake roller and/or to an intake channel of a grain conveyor, and a transverse conveyor belt disposed each on the left-hand side and the right-hand side of the center belt, to convey harvest to the center belt. The center belt, left-hand and right-hand transverse conveyor belts are behind a cutter bar, seen in the direction of travel, with each being operated with an individual belt speed. The combine harvester and/or belt cutting unit has a control unit configured to automatically control the belt speeds of the left-hand and right-hand transverse conveyor belts as a function of a forward travel speed, and the belt speeds of the center belt as a function of the forward travel speed or as a function of the belt speeds of the left-hand and right-hand transverse conveyor belts.
