Abstract: A combine harvester is configured with a chopping mechanism for chopping crop that includes a cutting cylinder equipped with knives, a knife carrier equipped with counter-knives and a friction concave plate and, downstream thereof a rasp bar. The knife carrier and the friction concave plate are each swivellable about a swivel axis, which enables the knife carrier and the friction concave plate to be moved into a position in which the counter-knives, the rasp bar or both extend at least partially into a crop stream passing through the chopping mechanism. The knife carrier and the friction concave plate are each adjusted using an actuator without the use of tools.

Abstract: A self-propelled combine harvester has a threshing mechanism composed of at least one aggregate selected from the group consisting of a threshing part, a working unit, and both, at least one stripping unit which is assigned to the at least one aggregate, and at least one rotary chamber configured on the at least one stripping unit on a circumference of the at least one aggregate.

Abstract: A stalk and chaff distribution arrangement in an agricultural harvesting machine having a chopping device arranged in a discharge region of the machine includes first and second blowers arranged adjacent to each other in the discharge region and each blower having a rotary shaft, a crop inlet opening, and a crop outlet opening; a crop dividing plate associated with the first and second blowers, the crop dividing plate having an apex and first and second diverging arms, said apex arranged in the direction opposite a crop flow from the chopping device to the blowers; and a first adjustable partial casing moveably associated the first blower and adjoining the first diverging arm, said first adjustable partial casing arranged circumferentially with the first blower; whereby a direction of the crop flow from the crop outlet of the first blower is changed when the first adjustable partial casing is moved.

Abstract: An agricultural harvesting machine has straw walkers or the like, an air sieve device, a straw chopping device, and a variable straw and chaff distribution arrangement. The arrangement includes an articulated lever combination; a servo element associated with the articulated lever combination; preferably two rotary distribution blowers each having a material inlet opening and a rotor circumference and being connected to the articulated lever combination. The rotary blower is movable between two different plane-parallel positions by the articulated lever combination and servo element. A guide is provided for supplying chaff radially to the distribution blower.
