Abstract: A threshing or separating concave for grain harvesting is equipped with curved cheeks, between which concave bars having an elongated cross-sectional profile extend, the curved inside edges of which are provided with a rounded inside edge, and having concave rods extending in the direction of the curve, which pass through holes in the concave bars that are immediately adjacent to the rounded inside edge.

Abstract: A harvest header for a harvesting machine includes a carrying frame, a mechanism for receiving or cutting harvest material from a field, a control device, a power-operated actuator operably controlled by the control device, and a transverse conveyor screw movably controlled between two or more positions. The position of the transverse conveyor screw is adjustably controlled by the actuator in order to transport the harvest material to a discharge opening. The control device independently controls the actuator based on at least one harvest material property.

Abstract: A combine harvester includes a load-bearing undercarriage movable via a drivable device engaged in the ground, a threshing and separating device attached to the load-bearing undercarriage, and a feeder house attached to the load-bearing undercarriage. The feeder house includes an endless traction mechanism which circulates about a vertically movable lower deflection roller and a drivable upper deflection roller. A harvesting attachment is coupled to the feeder house for receiving or cutting off harvested crops which are lying or standing upright on a field and which are able to be supplied via the feeder house to the threshing and separating device. An actuator is actuated by an external force arranged for adjusting the vertical position of the lower deflection roller and is connected to a control device which is coupled to a sensor for determining a throughput by a transmission of a signal.

Abstract: A cutter head for a harvester, with a cutterbar for cutting crop from a field, a reel with reel fingers which is disposed above the cutterbar, and a cross conveyor for transporting the cut crop to a rear discharge opening. The reel includes reel arms that can be driven about a rotating axis, reel finger carriers supported on the reel arms so they can rotate about the lengthwise axes of the arms, with reel fingers mounted thereon, and an externally powered actuator connected to an electronic control unit for adjusting the rotary angle of the reel finger carrier relative to the reel arms.

Abstract: A combine (10) includes a cleaning system (28) and an air conduit (80), which air conduit is arranged outside of a side wall (78) and through which the cleaning air is conducted downstream of the cleaning screens (48, 50, 66) to a suction blower (86) of the straw chopper (68), which suction blower is driven by a drive shaft (96).

Abstract: The invention concerns a harvested crop chopper remains-and-distribution arrangement for a combine (10) with a straw chopper (60) and an impeller blower (80) arranged downstream of the straw chopper (60), that includes at least one impeller blade (82) arranged to rotate in a direction of rotation about an axis (84) for the distribution across a field of the harvested crop remains provided by the straw chopper (60). An axially outer region (104, 106,114) of the impeller blade (82) leading in the direction of rotation is curved or angled in the direction of rotation. The axial dimension of the axially outer region (106) of the impeller blade (82) increases toward the outside in the radial direction.
