A single pointed ripper bucket excavation tool (SPRB) for use mounted to an arm of an excavation machine has a body mounted for rotation from the arm and a pair of generally flat, side plates mounted to the body and narrowing from a first width in a region of the body to a second, relatively smaller width at a tip region spaced from the body. A single ripper tooth is mounted in the tip region of the ripper bucket. One or more plates are mounted to span a region between the side plates, rearward of the ripper tooth in a direction of ripping motion, to define, with the side plates, a ripper bucket volume for receiving material ripped from the substrate during ripping motion.
