  • Patent number: 4230188
    Abstract: The inverter section of the present peanut digger-shaker-inverter may be used under all types of field conditions and comprises two downwardly and inwardly inclined drums, each drum being associated with a set of inverting tines. Each drum includes a plurality of equally spaced discs each holding a plurality of curved finger rods with adjacent pairs of the inverting tines having portions straddling a disc and curving similarly thereto beneath the outer extremities of the curved finger rods so that peanut plants are subject to a positive force in moving along and through the set of inverting tines with the plants being bumped and agitated by the gentle prodding of the ends of the rods and thereby affording an additional cleaning or reshaking action which lets the loosened soil fall freely through the drums and not on the inverted peanut vines which have been deposited on the ground and also assuring proper drying conditions and minimum field losses of the peanuts.
