ABSTRACT:
A crop engaging device for conveying and/or treating crop comprises a support and a plurality of crop engaging elements extending outwardly from the base. The device may be a stationary array of elements protruding into a crop flow, or a rotor which may be driven to convey or retard crop, or may be freely rotating. The crop engaging elements may be outwardly extending fins, or transversely extending ribs, or 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. Each fin may be inclined relative to the direction of crop flow to impart lateral movement to the crop. Two cooperating rotors may have crop engaging elements which intermesh so that ribs or discs on one rotor press crop onto sharp tips of brushes or fins on the other rotor to condition the crop. Transverse ribs may be radially sprung to avoid damage. Outwardly extending fins may have reclined, stepped profiles to improve crop engagement and release.
