ABSTRACT:
A compact, efficient grave digger is disclosed including a support frame and an excavation assembly which is carried by the support frame. The excavation assembly moves in a vertical direction beneath the support frame so that a grave may be excavated in a single downward pass of the excavation assembly. The grave digger includes a plurality of endless conveyors which loosen and remove the earth from beneath the excavation assembly. The support frame includes ground engaging wheels so that the grave digger may be selectively positioned at the grave site. Hydraulic jacks connect the excavation assembly with the support frame so that the excavation assembly may be raised and lowered with respect to the support frame. The excavation assembly may be adjusted so that graves of different lengths may be excavated.
