ABSTRACT:
An auger assembly for drilling holes in the ground includes an auger blade mounted for vertical movement and a dirt retaining shell that surrounds the auger blade also mounted for vertical movement in relation to the auger blade. When the hole has been drilled to the length of the auger blade, the retaining shell is lowered down into the hole to surround the auger blade and the auger blade and the retaining shell are removed from the hole simultaneously. The retaining shell retains the dirt on the auger blade to prevent the dirt from falling back into the hole. The drilling and removal of dirt is repeated until the hole reaches the appropriate depth. A pair of lateral extensions provide a cutting edge on the perimeter of the auger blade in order to provide a hole which is slightly larger in diameter than the diameter of the auger blade to permit the retaining shell to be lowered around the auger blade. A pair of sweeper blades mounted coaxially with the auger blade but independent of the auger blade and oriented adjacent the surface of the ground disperse dirt being removed from the ground to prevent the dirt from falling back into the hole. The entire auger assembly is mounted on a tractor or other vehicle for transporting the auger assembly through the field. Hydraulic, electric or pneumatic equipment can be used to power and actuate the auger assembly.
