The earth boring/drill device is arranged on a chassis with a plurality of upwardly depending support posts connected by horizontal support elements along with a mechanical means of reciprocating up and down a motorized power auger comprised of a shaft with a helical blade and cutting tips of hard wear-resistant material on the cutting end to drill a pit to a predetermined depth and predetermined diameter and then mound up excavated soil in an annular shape around the perimeter of the drilled pit as the auger is disengaged.
