A weed seed devitalization arrangement for use with a. combine harvester, attached to the combine harvester, towed behind, or standalone. The weed seed devitalization arrangement receives weed seeds entrained in a. portion of the air and material previously discharged from a combine harvester or other crop/lawn cutung apparatus. The weed seed devitalization arrangement includes a roton'stator arrangement including but not necessarily excluding other elements, one or more stationary substantially circular array of weed seed impact members, the members being arranged so as to impact weed seeds being provided into the substantially circular array; and one or more rotatable substantially circular array of weed seed impact members, the rotatable array movable with respect to a stationary substantially circular array of weed seed impact members, the impact members of the rotatable substantially circular array arranged to impact weed seeds being directed through the rotatable substantially circular array. Another element may be a driven rotating clement at or near the central portion of the rotor/stator arrangement for receiving the portion of air and material discharged from the combine harvester entrained with weed seeds and for providing a flow of air and entrained material including weed seed into the arrays of the arrangement.

A cutting device for agricultural harvesters has a conveying channel and pivotably supported cutting knives arranged in a row on a frame. The cutting knives project in the cutting position into the conveying channel. A conveying member with conveying tines, rotatingly driven about a horizontal axis, interacts with the cutting knives for comminuting crop. Individual adjusting devices, each associated with one cutting knife, yieldingly support the cutting knives in the cutting position. A knife switching device is provided to move the cutting knives from the inoperative position into the cutting position. With a preselecting device a desired group of cutting knives can be selected that is pivoted into the cutting position upon activation of the knife switching device. The preselecting device is activatable with reduced force expenditure by eliminating resistances, caused by adjusting and connecting devices of the knife switching device, when preselecting the desired group of cutting knives.

An agricultural combine including a residue spreading system adapted for spreading residue onto a field. The residue spreading system includes a seed container and a seed dispensing system adapted to dispense seeds from the seed container into the residue so that, in operation, the dispensed seeds are spread onto the field together with the residue.

A method of measuring residue ejected from an agricultural machine as the agricultural machine harvests a field includes transmitting an electromagnetic pulse toward a volume generally rearward of the agricultural machine, measuring a reflection of the electromagnetic pulse, calculating a property of residue ejected from the agricultural machine based on the measured reflection of the electromagnetic pulse, calculating a location at which the residue is expected to land in the field, and generating a residue map correlating an amount of residue with locations in the field.

Weed seeds are destroyed in the chaff from a combine harvester by repeated high speed impacts caused by a rotor which accelerates the discarded seeds in a direction centrifugally away from the rotor onto a stator including 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. A transfer auger at the rear edge of the combine sieve carries the weed seeds outwardly to respective weed seed destructors driven by the shaft of the transfer auger. The seeds are discharged radially through a discharge opening, where the angle of the discharge around the rotor axis can be changed to direct the seeds towards the guide fins of the tailboard of the chopper, or into the housing of the straw chopper.

A self-propelling combine and a method for operating a self-propelling combine are disclosed. The combine includes an axial spreader, which generates a residual flow of material and supplies the residual flow of material to a downstream distribution device that discharges the residual flow of material from the combine. The axial separator in the end-side material delivery region has at least one guide element that may be moved by an actuator, thereby affecting a distribution of the exiting residual flow of material over the supply width of the distribution device. The distribution of the residual flow of material is detected by at least one sensor unit, and when a deviation from a target distribution is detected, the guide element is adjusted. A control device receives and uses a signal representing a side wind used to automatically adjust of the at least one guide element.
