Drill attachment for tilling soil

A rotary till plate, comprising:

• a generally planar body member defining a first major surface adapted to operatively face soil and a second major surface distal thereto and having a center of rotation about which said generally planar body member is configured to operatively rotate;
• at least one perforation open and extending entirely from said generally planar body member first major surface to said generally planar body member second major surface;
• and
• at least one tooth protruding from said generally planar body member first major surface adjacent to said at least one perforation and extending longitudinally therefrom and configured to operatively extend into said soil;
• wherein said at least one tooth is unitary with said generally planar body member and further comprises matter displaced from a plane defined by said generally planar body member;
• wherein at least one tooth is angularly offset from said generally planar body member at an angle intermediate between parallel and perpendicular to a plane defined by said generally planar body member;
• and
• wherein said at least one angularly offset tooth further comprises a length terminating at a first end adjacent said generally planar body member and terminating at a second end distal thereto, and a major surface extensive along said length, said major surface twisted about said length from generally parallel with said generally planar body member first major surface adjacent to said generally planar body member to facing in a more outward radial direction distal thereto.

A rotary weed out tool, comprising:

• a generally planar body having a center of rotation about which said generally planar body is configured to operatively rotate;
• a pair of teeth spaced from each other and depending from said generally planar body and spread apart from each other with increasing distance from said body;
• a first tooth tip depending from a first one of said pair of teeth;
• a second tooth tip depending from a second one of said pair of teeth;
• said first tooth tip decreasing in distance from said second tooth tip with increasing distance from said body;
• wherein each one of said pair of teeth are displaced by an equal amount and in an opposite direction from being directly transverse to said center of rotation.
