An agricultural vehicle including at least one threshing rotor and an auger bed located underneath the at least one threshing rotor. The auger bed has a working position and a cleaning position. The auger bed includes a frame, a plurality of augers rotatably coupled to and supported by the frame, and a trough portion moveably connected to the frame. In the working position the bottom surface of the trough portion is positioned underneath the plurality of augers and in the cleaning position the entire trough portion is moved relative to the frame so that the bottom surface of the trough portion is not positioned underneath at least a portion of the plurality of augers, creating an open space underneath the portion of the plurality of augers for allowing an unwanted material to pass therethrough.

A monitoring system for a combine harvester. The monitoring system includes a sensor configured to provide a measurement wave to a flow of crop residue on the harvester and to receive a response wave from the flow of crop residue. The monitoring system further includes a processor having an input terminal for receiving a response signal of the sensor representative of the response wave. The processor is configured to determine a crop parameter associated with the density of the flow of crop based on the response signal of the sensor. The processor further has an output terminal for outputting a density signal representing the crop parameter.

A work vehicle for working a swath of crop has at least one ground-engaging wheel or track mounted to the work vehicle and movable in a travel direction along a tread path. A first redistribution device is mounted to the work vehicle to move crop that is ahead of the at least one ground-engaging wheel or track relative to the travel direction. A second redistribution device is mounted to the work vehicle to move crop that is behind the at least one ground-engaging wheel or track relative to the travel direction. The first redistribution device is configured to open the swath of crop along substantially only the tread path ahead of the at least one ground-engaging wheel or track relative to the travel direction, and the second redistribution device is configured to close the swath of crop along the tread path behind the at least one ground-engaging wheel or track relative to the travel direction.

A drive unit for a grain elevator, in particular for agricultural machines, has a drive wheel operatively connected to a screw conveyor for conveying crop into the grain elevator. The drive wheel is provided with retainer means which may be engaged in a positive locking and/or friction-type connection with a continuous tension means of the grain elevator provided with one or more paddles so as to drive the continuous tension means. Several openings are provided in the drive wheel between the arms holding the retainer means in such a way that this allows or facilitates crop conveyed by the screw conveyor into the grain elevator along a direction of conveyance to flow through the drive wheel.

A separating rotor with a rotor tube for use on a combine harvester has a plurality of crop engaging finger elements. Each finger element is mounted to a respective finger support which is secured to the rotor tube. Each finger element has a planar body with a flared base portion which presents a leading edge to the crop material with a relatively shallow angle with respect to the tube.

A combine harvester is provided with a conveyance system for transporting crop material discharged by overhead grain separating apparatus to a grain cleaning shoe. The conveyance system includes a series of oscillating pans which move the grain in a generally longitudinal direction. A return pan conveys the collected material forwardly to a front discharge edge from where the material falls onto a stratification pan below. The stratification pan conveys the collected material rearwardly to a rear discharge edge from where the material falls into the grain cleaning shoe. At least one of the return pan and the stratification pan is non-rectangular and has a non-transverse discharge edge.

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.
