A grain header has a frame with a cutter bar affixed to the frame. A sub-frame is pivotably coupled to the frame and a mower cutter bar is coupled to the sub-frame. A swather is coupled to the sub-frame and arranged rearward relative to the mower cutter bar. A deflector is disposed between the cutter bar and the mower cutter bar. The deflector is moveable between a raised position in which the deflector permits crop material cut by the mower cutter bar to pass onto the swather, and a lowered position in which the deflector inhibits crop material cut by the mower cutter bar from passing onto the swather.

A multiple row sugar cane harvester having automatic and independent control of multiple base cutters utilized to severe sugar cane stalks in adjacent rows. Position sensors sense the height of the base cutters relative to the chassis of the sugar cane harvester and feed the signals to a controller for adjusting the height to a preselected level. The base cutters are individually driven by hydraulic motors through individual hydraulic circuits and the operating pressure is sensed and fed to the controller for determining whether a choke condition exists. A load sensor is incorporated between the linkage and the sugar cane harvester chassis for determining whether the base cutters have ground contact to elevate the base cutters.

In a combine harvester, the driveline coupling mechanism is configured to couple the header driveline to a jackshaft (22) extending from the feeder (8). The mechanism includes a pendulum arm (36) that is pivotably connected to the header (1). An actuator (45) is furthermore provided for driving a pivoting motion of the pendulum arm (36) about a pivot axis (37) oriented transversely with respect to the jackshaft. At the end of the pendulum arm, a bearing hub (30) is mounted including a shaft portion (32) that is rotatably coupled to the header driveline at one end and that includes one part (60) of a clutch at the other end. The second part (62) of the clutch is mounted on the jackshaft (22). The pivoting motion of the pendulum arm (36), driven by the actuator (45), closes or releases the clutch.

A gauging system is adapted for use with a crop harvesting header of the type having a pair of wing frame portions connected to a center frame portion by a balancing linkage and which is operable in a first mode of operation by engagement of a skid plate of each wing frame portion along the ground. In one embodiment of the invention, the gauging system includes i) outer gauge wheels supporting the outer ends of the wing frame portions such that the skid plate is at a controlled distance from the ground and ii) inner gauge wheels proximate the center frame portion for supporting the inner ends of the wing frame portions such that the skid plate is at a controlled distance from the ground according to a second mode of operation of the header.

An agricultural vehicle includes a chassis; a header carried by the chassis and including a cutter mechanism, the header being adjustable in a vertical direction; a swath roller carried by the chassis behind the header; a roller actuator connected to the swath roller and configured to adjust the swath roller in the vertical direction; and a controller coupled to the roller actuator. The controller is configured for: detecting when the header raises in the vertical direction; recording a header raising point where the header raises; determining when the swath roller reaches the header raising point; and signaling the roller actuator to raise the swath roller when the swath roller reaches the header raising point.

An arrangement for the control of an actuator (48) for the adjustment of an adjustable element (16) of an agricultural work machine (10) is equipped with a control unit (50) to produce adjustment signals for the adjustable element (16) in the sense of moving to a theoretical position, a control arrangement (62) of the actuator (48), coupled with the adjustable element (16), which receives the adjustment signals of the control unit (50), and a determination device (54) to make available at least one parameter (0), determined with the aid of recorded vibration characteristics of the system consisting of the adjustable element (16) and the work machine (10). The determination device (54) can be operated so as to determine at least one parameter (0) at the successively following time points and to supply it to the control unit (50). The parameter (0) serves to optimize the regulating behavior of the control unit (50).
