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.

Apparatuses and methods of feed accelerators of agricultural harvesters include one or more convertible sections that are convertible between two or more types of agitator assemblies. The feed accelerators may include a cylindrical body that may form one or more facets, and the feed accelerators may include an exterior wall and a plurality of paddles distributed along the exterior wall. The plurality of paddles may be arranged in a plurality of rows. The agitator assemblies may include a first type that includes an agitator having sidewalls that for a geometrical shape, such as a chevron that extends from the exterior wall. A second type of agitator may include one or more paddles that may align with one or more rows formed on the exterior wall.

Feed accelerator for an agricultural harvester

A harvesting machine that has a first rotor rotationally coupled to a chassis, a second rotor rotationally coupled to the chassis, and a spine separating the first rotor from the second rotor. Wherein the spine has threshing inserts coupled thereto to facilitate threshing of crop processed by the first and second rotors.

A combine harvester includes a housing, a separating system mounted within the housing for separating a seed material from a straw material, a cleaning system including a cleaning fan configured to produce a motive flow of air, a straw chopper operable to chop the straw material from the separating system into a chopped straw material, a spreading system positioned downstream of the straw chopper and configured to disperse the chopped straw material outside of the housing of the combine harvester, and an air discharge channel located downstream of the straw chopper and above the spreading system and configured to discharge a portion of the motive flow of air produced by the cleaning fan.
