  • Patent number: 6036600
    Abstract: A combine dust eliminator attachable to the feeder housing of a John Deere carbine consists of an elongate dust eliminator housing having a pair of dust discharge chutes at either end. The dust discharge chutes are swingably mounted on the dust eliminator housing and may be swung upwards toward the center of the dust eliminator housing for access to internal parts. Mounted on each dust discharge chute is a dust curtain which hangs downwardly outside the sides of the combine feeder housing. The dust eliminator housing is swingably mounted to the top surface of the combine feeder housing and tilts upwardly and forwardly to allow access to the combine feeder housing. Locking devices hold the dust eliminator housing in horizontal contact with the feeder housing while in operation. Within the dust eliminator housing is a shaft having a driven rotating fan at each end, near the dust discharge chutes.
