ABSTRACT:
A device for removing cores of soil from the ground including a drum member rotatably mounted on a frame. The frame is adapted for attachment to a vehicle to pull the drum over the ground. The drum has an internal chamber with an access door and a plurality of hollow soil probes mounted on the drum to remove cores of soil from the ground for collection inside the drum as the drum is pulled over the ground by the vehicle. A power cylinder is provided for raising and lowering the frame to thereby cause the drum to move into and out of engagement with the ground.
