An agricultural vehicle includes a chassis, a threshing and separating mechanism supported by the chassis and configured for threshing and separating a crop material, a cleaning system positioned downstream of the threshing and separating mechanism in a direction of crop material flow, and an auxiliary processing system positioned downstream of the threshing and separating mechanism in the direction of crop material flow. The auxiliary processing system has an inlet and an outlet, and includes a discharge chopper having an end and a first direction of rotation about an axis of rotation. The auxiliary processing system also includes at least one rethreshing element coaxially aligned with the discharge chopper and adjacent to the end of the discharge chopper and having a second direction of rotation opposite to the first direction of rotation of the discharge chopper.

An agricultural motor vehicle able to connect to a variety of agricultural implements, and comprising a structural set having four parts: a lower chassis, an intermediate structure, a front complementary structure, and a rear complementary structure. The set is supported over a set of front traction wheels and a set of smaller rear wheels and also houses a vibrating sieve, above which is located a beating cylinder, the front edge of which connects to a concentrating guiding roller and a hinged inlet nozzle, as well as a cockpit and a grain dumper located over the set. Preceding the grain dumper is a clean grain collection gutter, a motor power set, a suction cleaning set, a clean grain elevator and lastly, a retractable side belt, whose lower edge is hinged at its midpoint and located on the upper edge of the intermediate structure.

An agricultural harvester includes a threshing and separating system for separating grain from non-grain crop material, and a residue handling system for receiving at least a portion of the non-grain crop material. The residue handling system includes a chopper and a windrow arrangement, each having an inlet. A door is movable between a closed position which directs the non-grain crop material to the chopper and an open position which directs the non-grain crop material to the windrow arrangement. A feed roller is positioned adjacent to and between the inlet of the chopper and windrow arrangement. The feed roller is rotatable in a first direction which directs the non-grain crop material to the chopper when the door is in the closed position, and a second direction which directs the non-grain crop material to the windrow arrangement when the door is in the open position.

A combine harvester having a grain pan arranged to catch a crop stream, the grain pan being driven in an oscillating manner to convey the crop stream rearwardly to a rear edge. A cleaning unit including a fan for generating a cleaning airstream which is directed under the rear edge. The grain pan includes a floor profile which defines a transverse profile comprising ridges and troughs. The troughs provide a plurality of longitudinal channels, wherein the ridge-to-trough height increases in the direction of conveyance. Crop material conveyed by the grain pan experiences channels that deepen towards the rear edge of the pan.

In one aspect, a method for unloading harvested crop from an agricultural harvester may include monitoring a quantity of the harvested crop discharged from the harvester based on sensor data indicative of the quantity of the harvested crop discharged from the harvester. The method may further include controlling an operation of a flow control device of the harvester to halt transfer of the harvested crop from a crop tank of the harvester to a crop discharge system of the harvester when a first quantity of the harvested crop has been discharged from the harvester. Additionally, the method may include continuing to control an operation of the crop discharge system after halting further transfer of the harvested crop from the crop tank to the crop discharge system to convey any remaining harvested crop contained within the crop discharge system to the discharge location.

A combine grain cleaning system having front and rear rollers, a conveyor belt having an upper surface extending from the front roller to the rear roller, a motor operatively connected to the conveyor belt and configured to drive the upper surface in a belt travel direction from the front roller to the rear roller, and a baffle located adjacent the rear roller. The baffle has a leading edge, a trailing edge located behind the leading edge with respect to the belt travel direction and below the leading edge with respect to a vertical direction, and a baffle surface extending from the leading edge to the trailing edge. One or more sieves are located below the baffle, and a fan is provided to direct an airflow at least partially upwards in the vertical direction adjacent the rear roller. A method for separating grain is also provided.

A foldable auger having a first and second auger assemblies, each having a respective housing, auger screw and rotation axis. A pivot joins the assemblies, and is configured to permit the second auger assembly to fold relative to the first auger assembly. A first drive coupler is located at an end of the first auger screw and offset from the first axis, and a second drive coupler is located at an end of the second auger screw and offset from the second axis. A drive sleeve is rigidly connected to the end of the second auger screw. The drive sleeve has at least one slot that slidingly receives the second drive coupler. The second drive coupler is movable between a first position in driving connection with the first drive coupler, and a second position not in driving connection with the first drive coupler.
