  • Patent number: 4951584
    Abstract: A transplanter with a rigid frame has a stationary handle fixed to the upper portion of the frame and an open ended earth corer rigidly fixed to the lower portion of the frame. The corer is an open ended casing of circular horizontal cross-section in which the diameter of any lower cross-section is greater than the diameter of any higher cross-section. As downward and reciprocating rotational forces are exerted on the handle and the core penetrates the earth surrounding a plant, earth nearer to the surface is compacted, facilitating removal of the corer from the earth and removal of the core from the corer. Preferably, the lower edge of the core will be serrated to facilitate the earth cutting process. An ejection assembly is manually vertically reciprocated to press the core downwardly out of the corner. The ejection assembly includes rods which hinge outwardly from the corer so as not to damage plant foliage.
