ABSTRACT:
A chopper and discharge apparatus includes a stationary housing for attachment to the rear discharge of a combine harvester so that straw is fed from the combine into an inlet of the housing and is discharged from an outlet of the housing. Within the housing is mounted a hub for rotation about the horizontal axis with the hub carrying a plurality of lugs at angularly and axially spaced positions therearound, each lug carrying a pair of pivotal blade members which are rotated with the hub in the form of flails. Each lug is associated with a stationary blade on the inside of the housing so that the pair of blades carried on each lug sweep past the stationary blade each on a respective side of the stationary blade. The blade members include some flat cutting blades in a center section and only fan blades in end fan sections.
