Abstract
The discharge hood of an agricultural combine has a housing suspended from the bottom thereof in disposition for receiving straw from straw walkers of the combine into a rotary chopper which impacts the straw and propels it rearwardly out through a spreader, while at the same time creating a current of air flowing through the housing. A second inlet positioned forwardly adjacent the straw inlet of the housing is located to receive a stream of chaff from a forwardly disposed chaff discharge of the combine so that both the chaff and the straw are passed through the chopper, admixed into a single stream, and propelled upwardly and rearwardly from the combine to be strewn and scattered across the ground behind the advancing machine. A booster fan adjacent the chaff discharge augments the air suction created at the chaff inlet of the housing by the high-speed chopping rotor to assure conveyance of the light chaff particles across the free space between the chaff just discharged and the chopper housing.
