Weed seeds are destroyed in the chaff from a combine harvester by repeated high speed impacts caused by a rotor mounted in one of a pair of side by side housings which accelerate the discarded seeds in a direction centrifugally away from the rotor onto a stator including angularly adjustable stator surfaces around the axis. Thus the discarded seeds rebound back and forth between the rotor and the stator to provide a plurality of impacts. The seeds are carried axially of the rotor by a controlled airstream so that they move to an axial discharge location where a discharge fan is mounted. The angle of the discharge around the rotor axis can be changed to direct the seeds to the side of the combine away from a straw chopper, towards the guide fins of the tailboard of the chopper, or into the housing of the straw chopper.

A combine including a chassis, a crop residue handling system including a residue chopper, residue spreader, a spreader chute and a swath selection door, a receiver configured to determine a location of the combine, and a controller that controls the residue handling system. The controller configured to determine the location of the combine on a map, execute a crop residue spreading mode in response to the controller determining that the location of the combine is located in a designated crop residue spreading zone indicated on the map, and execute a crop residue windrow mode in response to the controller determining that the location of the combine is located in a designated crop residue windrow zone indicated on the map.

A spreader system for use in an agricultural harvester having a threshing system and a cleaning system. The spreader system includes a chopper for the chopping of straw from the threshing system and a chaff spreader system and a straw spreader system. The chaff spreader system is configured to receive a flow of chaff from the cleaning system; and the straw spreader system is configured to receive a flow of straw from the chopper. The chaff spreader system is configured to emit a chaff airflow stream in a first flow path, and the straw spreader system is configured to emit a straw airflow stream in a second flow path. The first flow path and the second flow path intersect at a place of confluence apart from the chaff spreader system and the straw spreader system.

A cutting device for comminuting crop residues or catch crops on agricultural land is described. The cutting device is designed to be rotatable around a center longitudinal axis (MLA) and, to this, it has at least one bearing unit for rotatably mounting. The cutting device includes first and second respectively elongated cutting blade element, as well as at least one holding means for holding the cutting blade elements. The elongated cutting blade elements each comprise a cutting edge section and a connecting section lying opposite to the cutting edge section and are radially orientated in such a way that the cutting edge sections of the elongated cutting edge sections are arranged at a radial distance from the center longitudinal axis. The cutting blade elements are directly connected to each other with the aid of the holding means, wherein the connecting sections of the cutting blade elements are arranged directly adjoining one another in a center region of the cutting device receiving the center longitudinal axis (MLA).
