A grain cart and foldable auger assembly having an upper auger assembly portion with a discharge portion, a lower auger assembly portion with an intake portion, and a compound angle joint that allows the upper auger assembly portion to be moved between operating and transport positions. When in an operating position, the upper auger portion and the lower auger portion are offset from each other by an operating offset angle. When in a transport position, the upper auger assembly portion is offset from the lower auger assembly portion by a transport offset angle such that the upper auger assembly portions folded across the front of the grain cart in a non-obstructive and non-protruding manner.

Disclosed is an articulated harvesting combine of a forward power processing unit (PPU) having a forward set of wheel assemblies and a rear grain cart connected by an articulating joint assembly. Bonus sieves assemblies are located in the outer rear of the PPU for accepting grain from concaves and grates assemblies located forward of the bonus sieves assemblies. The bonus sieves assemblies accept tailings from the concaves and grates assemblies for additional separation of grain from material other than grain (MOG). New and separate airflow is provided for the bonus sieves. The bonus sieves tailings are returned to the bonus sieves for rethreshing, optionally after being particulated and air separation performed.

An agricultural harvester includes: a chassis; a cleaning system carried by the chassis; a crop material elevator supplied with crop material that has passed through the cleaning system; and an auger supplying the crop material from the cleaning system to the crop material elevator. The auger includes: an auger axle configured to rotate and defining an auger axis of rotation; a first flighting having a first helical direction and configured to be rotated by the auger axle; a second flighting having a second helical direction opposite to the first helical direction, the second flighting configured to be rotated so as to direct crop material conveyed by the first flighting back toward the first flighting; and a thrower connected to the first flighting and the second flighting and configured to convey crop material transversely relative to the auger axis of rotation.

A combine harvester including threshing and separating apparatus which are arranged to process a cut crop stream and each having a grate arrangement through which material separated from the crop stream falls under gravity. Grain conveyance means arranged below the threshing and separating apparatus catch the falling grain and material other than grain (MOG). A stratification pan is located below a front region of the threshing and separating apparatus and a return conveyor is located below a rear region of the threshing and separating apparatus, both conveyors being driven in a oscillating manner. The return conveyor conveys said grain and MOG in a forward direction to a front edge thereof which is located above the stratification pan. The stratification pan conveys collected material rearwardly to a rear edge from where the collected material falls under gravity into a cleaning unit. An accelerator roller is provided and is rotatably driven on a transverse axis in front of the front edge of the return conveyor. Material caught by the return conveyor is incident upon the accelerator roller and paddles provided on the accelerator roller serve to accelerate the material from the return conveyor forwardly.

A bubble-up auger assembly for an agricultural vehicle includes an auger at least partially surrounded by an outer tube. A bracket is configured to be non-rotatably connected to a rockershaft of the agricultural vehicle for rotation about a first axis. A slide rod is connected to the outer tube and the bracket. The slide rod is configured to cause the auger to move between a raised position and a lowered position in response to rotation of the bracket. In the lowered position of the auger, an axis of rotation of the auger is oriented oblique to the first axis.

An auger for filling the grain bin of combine harvester has a reduced pitch of the auger at an upper section. This reduced pitch changes the angle at which grain is released from the auger, and thereby reduces the amount of grain that is undesirably ejected from the grain bin during filling of the grain bin.
