Abstract (en)
An earth working machine for removing the surface layer of a paved surface or soil includes a rotor assembly having a drum (39), a plurality of bit holders (100) secured to an outer periphery of the drum and a plurality of cutter bits (160) one being positioned in each of the holders. Drive means are provided for rotating the drum, and the drum is massive enough and rotates at a high enough velocity to have a kinetic energy greater than 117 J/cm of drum width whereby the surface layer of the ground is sufficiently removed.
