Abstract: A drill attachment (1) for tilling soil has an extended drill shaft (10) that is coupled with a till plate (30). The combination may be driven by an ordinary hand drill. Drill shaft (10) has a stabilizer tip (11) that protrudes beyond till plate (30). Till plate (30) includes a plurality of teeth (32-34, 36-38) that dig into and work top soil, while a generally planar disk-shaped body member (39) at the top of till plate (30) prevents till plate (30) from sinking below the surface of the soil. Teeth (32-34, 36-38) are stamped from till plate (30), forming openings in the generally planar disk-shaped body member (39). These openings and other optional openings (35) cooperate with the teeth (32-34, 36-38) to further break up clumps of soil, and help to balance forces from the teeth (32-34, 36-38) pulling into the soil against the force of the body member (39) that resists sinking into the earth. Optional weed-out and hole tools are also disclosed.
