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.
