ABSTRACT:
A ring stand splits to encompass a tree to be transplanted and then is formed back into a circular ring in approximately concentric relationship to the tree. A plurality of curved hollow stanchions extend upwardly from the stand, and a curved spoon is slidably mounted with respect to each of the stanchions and the stand for movement between a position above the earth and a position down into the earth to join with all of the other spoons to separate from the earth a tree ball consisting of the tree's roots and the earth surrounding those roots inside of the spoons. To power the spoons, a rack is provided on an inwardly facing portion of each of the spoons and a matching rack is provided on an outwardly facing portion inside of each of the hollow stanchions. Pinions are situated in meshing relationship to each rack, and a hydraulic linear motor is provided to move the pinions to cause a movement by the associated spoons to be twice that of the pinions. Power means including a vehicle are provided to lift the ring stand, spoons and stanchions and the tree and tree ball from the earth; to tip this assemblage; to transport it to the location where it is to be transplanted; and to deposit it into a previously prepared opening of the same size.
