Patent ID: 7396085

Claim:
An apparatus for degrading a paved surface, the apparatus comprising: a first pavement degradation tool adapted to rotate about a first axis, the first pavement degradation tool adapted to degrade a paved surface substantially normal to the first axis; a second pavement degradation tool adapted to rotate about a second axis substantially parallel to the first axis, the second pavement degradation tool adapted to degrade a paved surface substantially normal to the second axis; and a linking mechanism to mechanically link the rotation of the first pavement degradation tool to the rotation of the second pavement degradation tool; wherein the linking mechanism comprises a first gear operably connected to the first pavement degradation tool, the first gear adapted to rotate about the first axis, and a second gear operably connected to the second pavement degradation tool, the second gear adapted to rotate about the second axis, wherein the second gear engages the first gear.
