ABSTRACT:
A lawn and garden tool for removal of plugs of earth from the ground. The tool has a plurality of blades rigidly affixed at the lower end of an elongate shaft, an earth-receiving channel being defined between inner surfaces of the blades. The inner surfaces of the blades are arcuate, generally being congruent with the curved surface of a circular cylinder aligned with the shaft. There are ledges defined around the periphery of the channel so that when the the blades are withdrawn from the ground, a plug of earth is held within the channel. In the disclosed embodiment, each ledge is defined along a lower edge of a lateral indentation of a blade. In each blade there is a pair of axially spaced indentations and a region of the blade between the indentations is directed radially inwardly of the circular cylinder to enhance the plug withdrawal capability of the tool. An upwardly biased plunger is included for ejection of a plug withdrawn from the ground.
