  • Patent number: 5156101
    Abstract: A portable tree and shrub transplanter which is easy to use by a landscaper and which reduces the shock a plant experiences during the transplantation process. The transplanter includes a rigid elongated handle extending to a blade to form a spade, wherein a rectangular frame is attached to an upper portion of the blade. The frame extends from the handle at an acute angle and receives three separate cutter blades in slots defined along the length of each side of the frame. When the blade is inserted into the earth, the frame is flush to the earth for aligning the transplanter about the plant. The blade in combination with the three cutter blades forms an inverted frusto-pyramid shaped receptacle about the root structure of the plant such that the portion of earth about the roots and the plant can be removed intact using the handle. The transplanter and plant can then be transported in a wheelbarrow to a selected location.
