ABSTRACT:
A bulb harvester with structure for lifting foliage attached to bulbs for presentation to an upper set of rotatably supported belts affixed to define a first foliage receiving crack. The first receiving crack is narrow for tightly gripping foliage attached to a bulb. The upper set of belts are positioned at a divergent angle relative to the ground. With rotation of the upper set of belts, gripped foliage with an attached bulb is drawn upward from the ground due to the divergent angle and transported toward the rear of the harvester. A lower set of elongated members define a second foliage receiving crack positioned below the first receiving crack to allow the first and second foliage receiving cracks to simultaneously possess the foliage of a bulb with the bulb positioned below a bottom plane of the lower set of elongated members. The upper set of belts are placed at a divergent angle relative to the lower set of elongated members to place the upper set of belts closer to the lower set of elongated members near the foliage lifting structure. The bottom plane of the lower set of elongated members provides an abutment surface for a bulb to abut against when drawn upward from the ground by the divergent angle of the upper set of belts with the abutting properly positioning the bulb prior to the cutting of the foliage from the bulb by cutting wheels.
