Abstract: A harvesting header for use with a crop-harvesting machine includes a header frame (202), at least one harvesting tool (204) carried by the header frame, a rotatable arm (306) coupled to the header frame at a pivot point (308) and extending forward of the harvesting tool, a wheel (304) coupled to the rotatable arm and configured to roll along a soil surface leading the harvesting tool, and a sensor (402) coupled to the header frame at the pivot point and configured to measure an angle of the rotatable arm with respect to the header frame. An agricultural harvester includes a chassis, a feederhouse, a processing system, a grain bin, a harvesting header, and a control system. A method of operating an agricultural harvester includes propelling the agricultural harvester through an agricultural field, sensing a contour of a soil surface leading harvesting tool; and adjusting a height of the harvesting header based on the sensed contour.

Abstract: A feederhouse assembly (200) for an agricultural harvester (100) includes a feederhouse (200) having an inlet end (204), ea yaw frame (214) adjacent the inlet end (204) and arranged to pivot about a vertical axis (216) relative to the feederhouse (200), and at least one hydraulic cylinder (220) configured to apply a hydraulic force to rotate the yaw frame (214) about the vertical axis (216). A method of connecting a harvesting header to an agricultural harvester includes applying a first hydraulic force from at least one hydraulic cylinder to a yaw frame (214), moving the agricultural harvester toward the harvesting header, securing the harvesting header to the yaw frame (214), and applying a second hydraulic force from the at least one hydraulic cylinder to the yaw frame (214) to orient the harvesting header at a right angle with respect to a longitudinal axis of the agricultural harvester (100).

Abstract: A rotary sieve cleaning shoe for cleaning grain, having at least one rotary sieve with a generally cylindrical volume arranged to rotate around a longitudinal axis and having at least one beater bar within the cylinder which remains stationary when the rotary sieve rotates.

Abstract: A feederhouse assembly for an agricultural harvester includes a feederhouse comprising an inlet end, a rotational shaft coupled to the feederhouse and defining a plurality of fluid passages therethrough, and a frame adjacent the inlet end and arranged to pivot about the rotational shaft relative to the feederhouse. The frame defines a crop opening therethrough and is configured to carry a harvesting header. An agricultural harvester includes a chassis, the feederhouse assembly mounted to the chassis, and a processing system carried by the chassis and structured to receive crop material from the feederhouse.

Abstract: A rotary sieve cleaning shoe having at least one rotary sieve, generally cylindrical and arranged to rotate around a longitudinal axis, and having an inner sieve and an outer sieve, each with holes, and one of the inner and outer sieves is longitudinally movable along the longitudinal axis relative to the other of the inner or outer sieve where the overlap between the holes varies such that the apparent size of a hole, corresponding to the overlap, through the rotary sieve is varied correspondingly.

Abstract: A rotary sieve cleaning shoe including a housing containing one or more rotary sieves, each sieve with a longitudinal axis and the housing is mounted to a combine harvester, by an actuator which is configured to vary the angle between the plane of the combine harvester and the longitudinal axis of at least one rotary sieve.

Abstract: An agricultural machine, preferably a combine harvester, which has a pivoting vehicle cab. The cab is pivotable relative to the main frame of the machine, about an axis of rotation transverse to the direction of travel of the machine. The cab is pivoted to allow an operator to view a front coupling of the machine, to observe the attaching or detaching of a work implement to the front coupling.
