Abstract: Two cooperating rotors are mounted for counter rotation about parallel axes for passage of crop between the rotors. At least one rotor has stiff, resilient, outwardly directed crop engaging elements having sharp tips on the outer ends for treating crop. The rotors rotate with the outer perimeters of the rotors overlapping and with regular inter-meshing of crop engaging elements on one rotor with crop engaging elements on the other rotor. Crop engaging elements of one rotor press crop into gaps between crop engaging elements on the other rotor so that the crop is laid across the sharp tips of the elements to treat the crop by a spiking action. The crop engaging elements may be outwardly extending fins, or transversely extending ribs of discs perpendicular to the axis of rotation. The crop engaging elements may have specified yielding characteristics, being yieldable in a preferred direction and being yieldable predominantly at a region spaced from the outer tip.
