ABSTRACT:
A hydraulically driven post hole auger apparatus for attachment to implement lifting mechanism of a vehicle. The apparatus includes a cylindrical housing having a speed-reducing gear box therein. The gear box has an output shaft extending through an opening in an end wall of the housing and adapted to have the auger attached thereto. A hydraulic motor in the housing is operatively coupled to the gear box. A universal joint mechanism couples the housing to a support member. The support member may be one end of a boom having its other end pivotally connected to the rear end of a tractor. Linkage connects the boom to the power-actuated lifting levers at the rear of the tractor for selectively raising and lowering the boom and the auger apparatus. The support member alternatively may be a bracket assembly adapted to be removably clamped to an arm of front end loader apparatus, the arm being pivotally connected to a tractor.
