ABSTRACT:
A main shroud is open at the bottom, and carries a housing on the upper end thereof. An annular director ring is mounted to extend in spaced relationship about the bottom of the main shroud, and a vertical shaft extends upwardly through the shroud and the housing and is connected with a power unit. An upper blower fan is mounted on the shaft within the housing, and generates an upward flow of air through the harvester. An impeller is mounted on the lower end of the shaft, and includes a mounting ring having external blades thereon which project into the annular space defined by the director ring. The impeller external blades generate a downward flow of air through the annular space, which is directed downwardly and inwardly to dislodge macademia nuts found in ground crevices, so they can be entrained in the upward air flow and discharged from the harvester.
