A stone trap assembly including an entrance and an exit. The entrance receives objects from a crop flow path for accumulation into the assembly during a harvesting operation, and the exit allows evacuation of the accumulated foreign objects out of the assembly during an evacuation operation. The assembly further includes a door configured to be rotatable around a first rotation axis, substantially transverse to the crop flow path, for movement along a door movement trajectory between a closed position and an evacuation position, and an impeller for forcing the accumulated foreign objects towards the exit. The impeller is configured to be rotatable around a second rotation axis, substantially transverse to the crop flow path, for movement along an impeller movement trajectory between a retracted position and an extended position closer towards the exit. The door and impeller are separately movable during at least a part of the trajectories.

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.

An agricultural harvester includes a chassis and a threshing and separating section carried by the chassis that is configured for threshing and separating grain from gathered crop material. The threshing and separating section includes at least one concave with at least one crop engaging surface having a high hardness coating formed thereon.

A combine harvester includes a rotor cage surrounding a rotor, a threshing space defined between the rotor cage and the rotor, and a transition section defining an infeed to the rotor cage. The transition section is mounted to the rotor cage at a location upstream of the rotor cage. The transition section has an inlet for receiving the crop material. The harvester also includes a crop conveying drum for conveying crop material to the inlet of the transition section and beneath the rotor. The crop conveying drum is at least partially encased by a shroud. The transition section includes a bottom wall, two side walls each having lower portions extending substantially vertical with respect to the bottom wall, and curved side walls each extending between the bottom wall and one of the side walls. The bottom wall is substantially tangential to a lower portion of the shroud.

A reinforced feeder housing for an agricultural machine includes a housing body having a top surface, a bottom surface, and two opposing side surfaces each extending between the top and bottom surfaces. The housing body includes a front opening through which crop material is directed into the feeder housing from a header of the agricultural machine, and a rear opening that is substantially opposite the front opening through which crop is expelled from the feeder housing and is delivered to a threshing mechanism of the agricultural machine. Various panels of the housing body are reinforced to improve the structural integrity of the feeder housing and prevent damage to the welds in the housing body.
