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 draper for an agricultural machine is disclosed. The draper includes a middle segment and two side segments, each with a frame, a flexible cutter bar, that is arranged or positioned on support arms pivotably articulated to the frame, as well as one or more continuously circulating conveyor devices arranged or positioned behind the cutter bar. The one or more conveyor device comprises a first guide roller that is arranged or positioned on the middle segment, and a second guide roller that is arranged or positioned at the end on the particular side segment around which the endless conveyor belt circulates. The two side segments are each pivotably connected to the middle segment by a frame joint about a pivot axis running substantially horizontally. The particular side segment has a belt guiding unit with a guide roller.

Abstract: A cutting unit for an agricultural working machine and a method for adjusting the cutting unit are disclosed. The cutting unit comprises a support body, a cutting device on the support body, a front suspension arranged on the support body on a first half of the cutting unit and has at least one wheel that rotates about a front axle and a rear suspension on the support body on a second half of the cutting unit and has at least two wheels that rotate about a rear axle, the front suspension and the rear suspension being rotatable about a respective rotary axis relative to the support body so that the front and rear suspensions can each be transferred between a transport position and a working position. The front suspension and the rear suspension, when in their respective working position, are moved relative to the support body between a high position and a low position.
