ABSTRACT:
A device for excavating material from around the periphery of a pole embedded in the ground. A frame is provided with a plurality of pole-engaging rollers adapted for placement against the pole periphery. An endless chain having one portion looped about the pole and another portion looped about sprockets carried by the frame secures the device to the pole. The sprockets are rotatably positioned on the frame at a slight inclination to a true horizontal plane and engage the chain for transporting the frame along the chain and in a descending helical path along the pole. A chain tension sprocket is provided and is movable toward and away from the pole axis to adjust the chain tension. An auger is carried by the frame and is adapted to cut an annular opening in the ground around the pole. Drive means are provided to urge the frame, and thereby the auger, around the pole and in a downward direction.
