Abstract: A vehicle having three or more wheels, supporting substantially all of the vehicle weight on its wheels, for removing a traffic marking from a road surface, has a vertically floating head cutter mechanism comprising a mounting shroud having an open bottom and being suspended from the vehicle in substantially vertically movable relation with respect to the vehicle by two or more vertical guides. The vertical guides define upper and lower limits of vertical travel of the mounting shroud and are dimensioned and otherwise adapted to locate the mounting shroud in an operative intermediate position between the upper and lower limit positions. First and second cutter head assemblies are operatively mounted within the mounting shroud adjacent the open bottom for counter-rotation about respective first and second axes, which axes are preferably canted from zero degrees to ten degrees to the vertical.
