ABSTRACT:
A stalk chopping adapter has a frame which can be attached to the front end of a harvester combine and supports two forwardly extending downwardly inclined parallel rotors which are driven in opposite directions. The rotors have longitudinally extending axially parallel or helical blades which cooperate to draw delivered stalks downwardly and to crush and/or sever the stalks. Alternatively, the blades of one of the rotors are slotted and only this rotor cooperates with stationary knives to sever stalks which are advanced toward the ground of a field for crops to be harvested under the combined action of the blades on the two rotors. The knives can be mounted on a cover which is pivotally mounted on the frame is adjacent the underside of the rotor having unslotted blades.
