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.

An agricultural machine includes at least one processing device for harvested material and a drive train for the at least one processing device. The drive train has an output transmission stage with an output shaft for the at least one processing device. The output transmission stage includes an input gear and a grooved shaft connected in a non-rotatable manner to the input gear and the output shaft in such a manner that a drive connection between the input gear and the output shaft is achieved via the grooved shaft. The grooved shaft is provided with a ring groove defining a predetermined breaking point. The ring groove is configured in the drive flow direction between the input gear and the output shaft, and the grooved shaft is accessible through an assembly opening on an input gear side of the grooved shaft. The assembly opening is axially aligned with the grooved shaft.

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 airflow system for a rotary harvester includes a cleaning charge fan assembly, a cleaning fan assembly, and bonus sieves with fan assemblies. Each of the fan assemblies is powered by a hydraulic motor. By linking the charge fan motor, the left/right tailings fan motors, and the cleaning fan motor in a series hydraulic circuit, each of the motors will increase/decrease in speed at the same time and by the same proportional amount.

Embodiments of an intelligent power allocation system include a ground traction undercarriage controllable to propel a hybrid combine over terrain, a separator device configured to separate grain from other crop material ingested by the hybrid combine, a mechanical powertrain including an internal combustion engine, and an electric drive subsystem containing a rechargeable battery pack and a motor/generator (M/G). A controller architecture is configured to monitor a current separator load placed on the hybrid combine when driving movement of the separator device during active harvesting. The controller architecture further selectively places the intelligent power allocation system in a separator power splitting mode in which the M/G and the internal combustion engine concurrently drive movement of the separator device based, at least in part, on whether the current separator load exceeds an upper load threshold.

A combine harvester including an axial flow crop processor fed by a tangentially impelling feed beater mounted for rotation on a substantially transverse axis, and a multi-speed beater drive system that includes a beater shaft upon which the beater is mounted via bearings to permit relative rotational movement, and a secondary shaft arranged parallel to the beater shaft. To achieve a first beater drive speed a first drive path is closed between the beater shaft and the beater. To achieve an alternative, second beater drive speed a second drive path is closed between the secondary shaft and the beater. Both the beater shaft and the secondary shaft are driven simultaneously during operation.
