A combine harvester includes: a grain conveyance mechanism for conveying grains from a threshing apparatus to a grain tank; a grain discharge apparatus provided in an end area of the grain conveyance mechanism, the grain discharge apparatus having a discharge case provided with a grain discharge opening, and a discharge rotor rotatably arranged in the discharge case; a pressed portion that is subjected to a pressing force applied by grains immediately before the grains are discharged by the discharge rotor; a load detector for detecting the pressing force exerted on the pressed portion; and a yield evaluator for evaluating the amount of conveyed grain based on a detection signal from the load detector.

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.

A return pan for an agricultural combine includes a textured floor, two augers, and two motors coupled to the two augers, respectively, to selectively drive the motors in rotation.

A dryer for installation on a self-propelled machine, such as a combine harvester, with recovery of the exhausted thermal energy coming from the endothermic engine of the latter. The dryer is of the on-line type and comprises at least two feed screws, internally to which grain is moved towards a tank and dried by the hot air coming from a first and second heat exchangers respectively, the first heat exchanger being crossed by the high temperature exhaust fumes of said endothermic engine and the second heat exchanger by the cooling liquid.

A threshing system of an agricultural harvester includes a rotor cage surrounding a rotor, a threshing space defined between the rotor cage and the rotor, and a transition cone defining an infeed to the rotor cage and the threshing system. A mating interface between the rotor cage and the transition cone is curved in three different dimensions of a Cartesian coordinate system for maximizing the threshing space. As viewed from above the mating interface of the threshing system, a convex portion of the rotor cage is mounted to a concave portion of the transition cone.

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.

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.
