Abstract: A threshing system for an agricultural harvester includes a rotor having a proximal end adapted to receive material from a feeding mechanism and a distal end. A discharge housing surrounds the distal end of the rotor. The discharge housing includes a side wall spaced radially apart from the rotor to define a discharge passage between the rotor and the discharge housing. At least one vane is pivotably mounted to the side wall of the discharge housing at a downward swept side of the rotor. The vane extends from the inner surface of the discharge housing. The position of the vane is adjustable to change a trajectory of material expelled from the discharge passage. The vane is positioned on a large diameter portion of the discharge housing in order to limit compression of the material as the material passes along the at least one vane.

Abstract: A transition device for a combine harvester includes a body having an inlet end and an outlet end. A plurality of vanes are positioned on an interior facing surface of the body for guiding crop material through the transition device. Each vane has a first end positioned either on or adjacent the inlet end of the body and a second end positioned either on or adjacent the outlet end of the body. An arc length between the first ends of two adjacent vanes of the plurality of vanes is less than or equal to an arc length between the second ends of the two adjacent vanes of the plurality of vanes, such that the crop material can expand between the two adjacent vanes upon travelling along a trajectory from the inlet end to the outlet end of the transition device.
