Abstract: A charge fan assembly is located behind the forward operator cab and draws air from about the top of the PPU and a portion of an airflow from the charge fan assembly is directed downwardly into the crossflow cleaning fan assembly. A pair of closely spaced-apart sheets create a venturi and speed up the charge fan airflow into the crossflow cleaning fan and impact the crossflow cleaning fan at an angle where the blades of the crossflow cleaning fan are widely open. The exhaust air from the crossflow cleaning fan is nearly the same across the entire lengthwise extent of the crossflow cleaning fan.

Abstract: A grain harvesting articulated combine includes a forward crop processing power unit (PPU), a rear grain cart, and an articulation joint that connects the PPU with the rear grain cart. The articulation joint includes a grain auger assembly running from the PPU to the rear grain cart for transferring clean grain from the PPU to the rear grain cart and has a forward end at the PPU and a rear end adjacent to the rear grain cart. The grain auger assembly is housed within a tube with a rotating auger housed therein. A grain yield sensor is carried by the rear grain cart and is located adjacent and to and beside the grain auger assembly wherein the auger housed therewithin throws grain against the grain yield sensor. The auger is terminated by a rotating paddle assembly that throws the grain against the grain yield sensor.

Abstract: An improved grain unloader for unloading grain from a grain storage bin of a grain harvesting combine is terminated by a hood having a lower grain exiting opening terminating the unloader wherein the hood reversibly moves laterally outwardly for directing the trajectory of the grain flowing therefrom. The hood has a lower grain exiting opening terminating the unloader wherein the hood includes an upper stationary slanted wall and a lower extendable hood portion, wherein the upper stationary slanted wall directs the grain downwardly when the hood is retracted and downwardly, and outwardly when the hood is extended. A linear actuator is attached between the hood and the unloader. Drawer slides connect the unloader and the hood for movement of the hood.
