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 concave assembly for an agricultural machine includes a frame pivotally connected to a structural component and a concave connected to the frame. The frame includes a trunnion having a front end and a rear end. A front arm and a rear arm are connected to the trunnion. A crossbar extends between the front arm and the rear arm. A rotating member rotatably connected to the crossbar. The concave includes a first outer support and a second outer support. An inner support is positioned between the first outer support and the second outer support. A plurality of separator bars extend between the first outer support and the second outer support.

Combine harvester concave assembly and attachment method

Systems and methods for automatically establishing a gap between a concave and a rotor of a rotary crop processing system are disclosed. Establishing the gap may include displacing the concave towards the rotor until contact is detected therebetween. Contact may be detected using a sensor configured to detect contact between the rotor and the concave. The sensor may be a knock sensor. The concave is displaced away from the rotor when contact is detected until contact between the rotor and the concave is no longer detected. One or more actuators may be coupled to the concave to move the concave relative to the rotor. In some implementations, the actuators may be operated in sequence to form the gap between the rotor and the concave.
