A header (102) for an agricultural harvester (100) comprising a frame (104), a cutter bar (106), a draper belt and a cutter bar support sub-assembly connected to the frame is disclosed. The cutter bar support sub-assembly generally includes a draper support sub-assembly (200A,200B) and a support arm subassembly. The draper support sub-assembly is pivotably connected to the support arm sub-assembly and pivotable about a longitudinal axis of the support arm sub-assembly. The draper support sub-assembly includes a first draper support (608) that includes a curved surface engaging the draper belt and a cutter bar mount (606) supporting the cutter bar. The support arm sub assembly includes a support member connected to the frame.

A control system for controlling pivoting of a header of an agricultural harvester. The control system includes first, second, and third header height sensors, each for mounting to a respective point on the header, each configured to provide a respective header height signal representing a respective measured header height of their respective point on the header above a ground plane. The control system further includes a header angle sensor configured to provide a header angle signal indicative of a pivot angle of the header about an axis; and a processor configured to: receive the signals; calculate an estimated first header height based on the pivot angle and the second and third header heights; determine a replacement first header height by selecting the smallest of the estimated and the measured first header height; and generate a control signal based at least on the replacement first header height.

A sickle knife drive for an agricultural vehicle generally includes a first pump, a first motor, a second motor and a drive manifold having a plurality of connections used for connecting to other devices of the sickle knife drive and/or to devices outside of the sickle knife drive. Operation of the first pump in a forward direction causes the first motor to drive a sickle knife gearbox to cut a crop. During the forward direction, the second motor provides cooling to the fluid circuit. When the first pump direction is reversed, the agricultural vehicle supplements a fluid flow to the fluid circuit to clear any jammed crop from the sickle knives.

A header for harvesting agricultural crops includes a cutter bar assembly coupled to a header frame, the cutter bar assembly flexible upwardly and downwardly relative to the header frame between opposite ends thereof for contouring to the field. The cutter bar assembly includes a guard bar extending across a front portion of the header frame between the opposite ends thereof, the guard bar split into at least a first lateral section and a second lateral section operatively coupled at a guard bar joint. A protruding element extending from the first lateral section is received by a receiving element on the second lateral section at the guard bar joint to horizontally align the first and second lateral sections of the guard bar between the opposite ends of the header frame while allowing relative lateral movement therebetween during upward and downward flexing of the cutter bar assembly.

An agricultural vehicle header suspension having a frame, a plurality of supports extending forward from the frame, an anchor plate, a frame pivot joining the frame to the anchor plate to be rotatable about a frame pivot axis, a frame actuator connected between the anchor plate and the frame and configured to resiliently hold the frame at a predetermined position relative to the anchor plate, and to allow the frame to move through a range of motion relative to the anchor plate, upon compression and/or extension of the frame actuator. The frame actuator may be, for example, at least one single-acting hydraulic actuator, mechanical spring, or a pneumatic cylinder.

A system for controlling harvesting implement height of an agricultural harvester may include a computing system configured to monitor the height of a harvesting implement of the harvester relative to a field surface based on the received sensor data. Additionally, the computing system may be configured to determine an implement height error signal by comparing the monitored height of the harvesting implement to a predetermined target height. Moreover, the computing system is configured to divide the determined implement height error signal into a first and second frequency portions, with the second frequency portion having a greater frequency than the first frequency portion. Furthermore, the computing system is configured to control the operation of first and second actuators of the harvester based on the first and second frequency portions of the implement height error signal, respectively.

row crop heads and pivoting assemblies associated with the row crop heads operable to displace a crop divider of the row crop heads during folding of a portion of the row crop head are disclosed. In some implementations, a pivoting assembly may include a first bracket coupled to a center frame of a row crop head, a second bracket coupled to a wing frame of the row crop head, and a rotatable locking component rotatably coupled to the first bracket. The rotatable locking component is operable to lock a row divider disposed at an interface between the wing frame and the center frame when the wing frame is moved from an unfolded position to a folded position relative to the center frame.

A driver assistance system of an agricultural harvesting machine with a harvesting header designed as a draper is disclosed. The driver assistance system comprises a memory for storing data and a computing device for processing the data saved in the memory. The draper comprises a central belt and at least one transverse conveyor belt arranged on the left side and the right side of the central belt for conveying the harvested material to the central belt. The draper forms, together with the driver assistance system, an automatic draper. The computing device operates the automatic draper as a characteristic diagram controller using the saved characteristic diagrams, with the automatic draper optimizing operating parameters of the draper and specifying the optimized operating parameters for the draper. The characteristic diagrams describe the relationship between the operating parameters and quality parameters, and a control characteristic curve is assigned to the particular characteristic diagram.
