An apparatus for degrading a paved surface includes two or more pavement
degradation tools, each rotating about an axis. The pavement degradation
tools are adapted to degrade a paved surface substantially normal to
their axes of rotation. A linking mechanism links the rotation of the
pavement degradation tools such that rotation of one causes the rotation
of the other. In selected embodiments, this linking mechanism includes
gears operably connected to the pavement degradation tools that rotate
with the pavement degradation tool about their axes of rotation. These
gears directly engage one another causing the gears, and their
corresponding pavement degradation tools, to rotate in opposite
directions.
