A combine for harvesting chick peas includes a first rotatable shaft having components that cut a crop and pass the cut crop in a rearward direction, and a drum that includes an outer shell with stationary threshers and a cut crop opening, a rotatable central mount, a plurality of rotatable threshers. Each of the rotatable threshers is attached to the central rotatable mount and in line with a stationary thresher. A plurality of cutters is attached to the outer shell, a flame source projects a flame into the drum, and a water source projects water into the drum. The cut crop passes into the cut crop opening, to be further cut by the plurality of cutters and threshed by the plurality of rotatable threshers, such that the flame and water are projected onto the cut crop, resulting in a processed crop and detritus that is separated from the processed crop.

An agricultural harvester has a chassis carrying a threshing and separating system for separating grain from Material Other than Grain (MOG). The threshing and separating system has a threshing rotor and at least one concave. At least one rasp bar is attached to the threshing rotor. The at least one rasp bar has an upper threshing surface and a trailing surface. The trailing surface is set at a draft angle. At least one trailing surface interrupter is located on the trailing surface and may be inclined slightly rearward from vertical. The trailing surface interrupters may be used with rasp bars with or without rasp bar spikes.

A threshing and separating system including a non-stationary rotor cage including a perforated cylindrical body extending in a longitudinal direction from a first open end portion to a second open end portion. The first open end portion supported by a first rotatable coupling point, and the second open end portion supported by a second rotatable coupling point. The threshing and separating system also includes a rotor configured to rotate within the non-stationary rotor cage to thresh harvested crop. The non-stationary rotor cage is configured to rotate about an axis extending between the first rotatable coupling point and the second rotatable coupling point, and to be rotationally driven by the rotor via the threshed harvested crop.

A spine for providing structural support for a dual rotor harvesting machine, the spine having a first surface that is solid and directed towards a first rotor configured to rotate about a first axis and a second surface that is solid and directed towards a second rotor configured to rotate about a second axis. The spine also having at least one threshing insert positioned directly on the first surface and extending longitudinally along the first axis of the spine and at least one threshing insert positioned directly on the second surface and extending longitudinally along the second axis of the spine.

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 arrangement for switching over a combine harvester between swath deposit operation and wide distribution operation comprises a front element and a rear element which follows downstream. The rear element may be attached in an articulated fashion, in an inherently rigid fashion, at its upstream end about a first pivoting axis and may be moved between a swath deposit position and a wide distribution position by an adjustment drive. The front element may be attached in an articulated fashion at its upstream end about a second pivoting axis, may be inherently rigid and may also be coupled to the adjustment drive.

The present invention comprises a removable cover plate assembly, which may be quickly attached, detached and adjusted to the exterior of a concave grate of a combine harvester in order to adjust the flow characteristics of the concave or separator grate assemblies. The cover plate assembly improves the threshing capability of the rasp bar threshing cylinder while simultaneously capturing additional threshed grain. Moreover, the cover plate assembly of the present invention enables a single set of concave grate assemblies to better harvest a wider variety of crop types.
