Abstract: A sensor arrangement for detecting properties of a mixture including grain and contaminants in a cleaning device of a combine harvester. The sensor arrangement is equipped with a sensor element for providing an output signal in respect of a property, detected by the sensor element, of the mixture adjacent to the sensor element. The sensor element is configured to be brought operationally continuously in succession into different positions in relation to the mixture in order to sense different points of the mixture in the different positions of the sensor element.

Abstract: A threshing concave for a combine harvester comprises a crop processing device which is arranged at the inlet to the threshing concave and can be adjusted between an active and an inactive position, adjustable elements which are arranged downstream of the inlet to the threshing concave and can be adjusted between an active and an inactive position, and an adjustment mechanism for separate adjustment of the crop processing device and the adjustable elements, which comprises a movable adjustment element which is coupled to the crop processing device and to the adjustable elements.

Abstract: A spreader of a combine for conveying crop residue rearwardly from a rotor assembly includes a frame coupled to the combine and has a top portion adapted to receive a portion of crop residue during a harvesting operation. An impellor includes one or more blades for rotatably conveying crop residue rearwardly, and an actuator is controllably moved between an extended position and a retracted position. The actuator is pivotally coupled to the combine. A linkage assembly is pivotally coupled to the actuator at one end and to the frame at another end. The spreader is disposable in a first position when the actuator is in the extended position, and the spreader is disposable in a second position when the actuator is in the retracted position. A movement from the extended position to the retracted position induces pivotal movement of the spreader from the first position to the second position.

Abstract: A combine double-decker crop residue spreader for use with a rotating chopper having chopper blades and through which air is blown may include a divider panel separating a lower portion from an upper portion of the spreader. The divider panel extends rearwardly from a location where the chopper blades transition from rotating towards the divider panel to rotating away from the divider. An airflow conduit extends above the divider panel in the upper portion to rearwardly direct air flow. At least one lower vertical panel below the divider panel in the lower portion rearwardly directs crop residue.

Abstract: A residue deflector is disposed in a combine body, and positioned along an airflow path to guide residue from an exit end of a cleaning shoe and a threshing and separation assembly, to a residue chopper. The deflector is configured with a plurality of spaced fingers so that air can pass through the deflector between the fingers.
