ABSTRACT:
Disclosed herein is a device for orienting a drilling auger disposed on and powered by a vehicle defined by a lower frame member carried by the vehicle, an upper frame member pivoted to the lower frame member for rotation about an axis, and an auger supporting framework pivoted to the upper framework for rotation about a second axis orthogonal to the first axis in which the rotation is controlled by hydraulic cylinders extending between the lower and upper frame members, and between the upper frame member and the auger supporting framework, respectively. The auger itself is driven by a power take-off on the vehicle in a preferred form which in conjunction with the preceeding structure allows the auger to address the earth in which the hole is to be drilled in substantially any angle above the surface of the earth.
