Patent ID: 8540033

Claim:
A land preparation apparatus comprising: a rotatable drum and a plurality of tool assemblies disposed on the rotatable drum, wherein each tool assembly comprises: a tool holder comprising: a tool holder mounting surface defining a V-shaped non-planar tool holder mounting surface profile; a first peg extending from the tool holder mounting surface, the first peg comprising a first opening disposed within a distal end of the first peg; a second opening disposed within the tool holder at an end of the tool holder opposite the first opening; a first hollow channel disposed within the tool holder between the first opening and the second opening; a second peg extending from the tool holder mounting surface, the second peg comprising a third opening disposed within a distal end of the second peg; a fourth opening disposed within the tool holder at an end of the tool holder opposite the third opening; and a second hollow channel disposed within the tool holder between the third opening and the fourth opening, wherein the first hollow channel and the second hollow channel are adjacent and parallel to each other; and the land preparation tool comprising: a tool mounting surface defining a V-shaped non-planar tool profile; a cutting surface disposed on a surface opposite the tool mounting surface; a first channel for receiving a first securing bolt disposed within the land preparation tool, the first channel extending from the tool mounting surface to the cutting surface; a second channel for receiving a second securing bolt within the land preparation tool, the second channel extending from the tool mounting surface to the cutting surface; and wherein the first channel and the second channel are adjacent and parallel to each other and the tool holder mounting surface profile is inverse to the tool mounting surface profile.
