Provided is a system and method for a hand tool with a plurality of quick release work heads. The hand tool includes a handle having a socket having a first longitudinal axis and an inner cavity extending rearward from an open distal end, the inner cavity having a first non-circular cross section transverse to the first longitudinal axis, the socket further having a quick release transverse to the first longitudinal axis, the quick release releasably disposing a locker transversely across a portion of the inner cavity. The hand tool also includes at least one work head having a second longitudinal axis and a shaft having a second non-circular cross section concentrically conforming to the first non-circular cross section of the inner cavity, the shaft further having a locking groove transverse to the second longitudinal axis and disposed to engage with the quick release locker when the shaft is disposed within the socket of the handle. An associated method of use is also provided.

A yoke for a dipper handle assembly used on a power shovel. The yoke is constructed at least in part of a transition portion and associated lugs manufactured of a forged material as opposed to castings. Accordingly, the yoke is less prone to failure and easy to repair in the field.

An automated post hole digger for efficient, assisted hole digging includes a base plate having a top side separated from a bottom side forming an inner cavity. A pair of jaws is pivotably coupled to the base plate. A bottom end of each of a pair of handles is coupled to the pair of jaws to move the pair of jaws between an open position and a closed position. A hole saw is coupled to the base plate and comprises a motor, a battery pack, a piston coupled to the motor and extending through the bottom side, and a bit head that is selectively engageable with the piston. The piston is driven by the motor and the bit head is configured to break up hard soil, clay, concrete, and other material. A plurality of controls is coupled to the pair of handles to operate the hole saw.

The present invention relates to a hollow boring auger for use for poles, including a first and second mounting part moveably connected, one to the other, to substantially encircle the pole. A first and second auger part are also included, correspondingly attachable to the first and second mounting part, to substantially encircle the pole, A rotation apparatus associated with the mounting parts and the auger parts is included such that in use the auger parts can be rotated about the pole to bore a hollow trench about the pole. The invention also relates to a method of use.
