A combine (20) harvester includes a cage (32′) at least partially surrounding a rotor (28′) for threshing crops in the space (34) between the cage (321) and the rotor (28′). An auger (302) is at least partially positioned within the cage (32′) and is connected to the rotor (28) for rotating therewith. The auger (302) includes vanes (312) for transporting crop from the rotor (28′) and towards an outlet of the cage (32′). A chopper (320) is positioned either at or adjacent the outlet (310) of the cage (32′). A rotational axis (30) of the chopper (320) is substantially aligned with an axis of rotation of the auger (302) and the rotor (28).

A harvester capable of autonomous travel in a field includes: a harvesting unit that harvests a crop from the field; a conveyance device that conveys, toward the rear of a harvester body, a whole culm of the harvested crop harvested by the harvesting unit; a detection sensor that detects a drive speed of the conveyance device; and a clog determining unit that determines a clog of the harvested crop in the conveyance device on the basis of the drive speed. The clog determining unit outputs a vehicle stop command that stops the harvester body when the drive speed becomes lower than a pre-set first threshold during the autonomous travel.

An adjustable vane system for use with a rotor cage of a threshing system of an agricultural harvester. The vane system includes a vane having a generally helically curved inner profile; a surface being an outer profile that is opposite the inner profile and is generally helically curved over a portion of the vane; a first flat portion proximate an end of the vane on the outer profile; and a second flat portion proximate to another end of the vane on the outer profile.

A threshing system including a rotor cage with a plurality of slots therein, a first bank of vanes and a second bank of vanes arranged within the cage. An adjustable vane control system is coupled to the rotor cage and the banks of vanes. a first and second member are respectively pivotally coupled the vanes in the first bank and the vanes of the second bank through corresponding slots. Linkages couple an arm to the members. The first and second members each having a range of travel defined by the slots. The members each having a surface facing the outer surface of the rotor cage, the surfaces of the first member and the second member each remain tangent to the outer surface of the rotor cage as the first member and the second member are moved within their range of travel.

A self-propelled harvesting machine such as a combine harvester has multiple working units for processing crop picked up from a field, a driver assistance system for the sensor-supported control of the working units, an environmental sensor system for detecting environmental information and spatial areas of applicability located in the environment of the harvesting machine. The driver assistance system has a memory for storing data and a computing unit for processing data, including the data stored in the memory. A functional system model for at least one part of the harvesting machine is stored in the memory. The computing unit functions as a characteristic control on the basis of the system model and autonomously determines machine parameters of at least one working unit and specifies these to the particular working unit.

An agricultural working machine embodying a combine harvester for processing crop includes an intake conveyor mechanism for picking up the crop, a moisture content sensor arrangement for measuring a moisture content of the picked-up crop and generating a crop moisture signal based on the measured moisture content. A throughput sensor arrangement, preferably a layer thickness sensor arrangement, determines a throughput quantity of the picked-up crop. The crop moisture content signal is corrected on a basis of the throughput quantity that is determined.

A rotor housing assembly for a harvester has at least one cover plate forming part of a generally cylindrical shaped rotor housing, a central longitudinal axis, and an inner surface, which, when mounted, faces the central longitudinal axis and has a first radius, and one or more rotatable vanes which each are rotatably mounted on an inner surface of the cover plate facing the central longitudinal axis at a rotation point. The one or more rotatable vanes have a contact surface with the inner surface. The contact surface has a second radius that is larger than the first radius of the cover plate. The inner surface of the top cover plate, per rotatable vane, has a symmetrically curved shape such that, during a rotation of the respective vane, the contact surface of the vane with the inner surface of the cover plate substantially follows the shape of the inner surface.
