Abstract: The attachment is mounted on the combine near the chaff discharge outlet and includes a transverse trough positioned to receive chaff particles issuing from the outlet. A powerful, fast-moving stream of air introduced into the trough near its center is split into two oppositely moving streams directed toward opposite ends of the trough so that the chaff particles become entrained in the streams and propelled to outboard locations before dropping to the ground in a dispersed and scattered condition.

Abstract: An intake hose on one sidewall of the machine communicates with a source of negative pressure to create a powerful suction air stream that draws particulate materials through the hose and propels them into a chamber where they separate from the air stream and charge by their own momentum directly into a discharge auger assembly on the opposite sidewall of the machine. The auger assembly joins with the sidewall of the machine at an upwardly and outwardly inclined attitude for elevating the materials into a suitable receiving truck or trailer alongside of the machine, and a lower longitudinal portion of the assembly which adjoins the sidewall is open along its length to facilitate the unimpeded reception and entry of particulate materials from the hose directly into the auger.
