Abstract:
The split base frame for encircling a tree to be transplanted carries a plurality of upright blade guide units for associated digging blades. Each blade is guidably supported for movement in a guided path from an upper position out of the ground to a lower ground inserted position wherein the blades are inclined downwardly and inwardly of the base frame to relatively converged positions to form a tree ball for the roots of the tree being excavated. A blade is moved by an upright lift screw and nut assembly located in each guide unit and wherein the nut assembly is attached to an associated blade. Coacting means on the nut assembly and on the guide unit define the guided path of movement of the blade with the nut assembly being traversible axially of the screw shaft on rotation thereof by a reversible rotary power means.
