Abstract
A road working machine for cutting into a road surface includes a power driven, cutting tooth carrying rotor comprising a plurality of rotor segments removably attached to a shaft to vary rotor width. Each of the segments includes a plurality of subsegments attached to one another and to the rotor by threaded fasteners. Rings supporting a higher concentration of cutting teeth angled toward the ends of the rotor can be secured to the endmost rotor segments for edge cutting. A cover for the rotor includes an adjustable baffle which may be secured at any of a plurality of positions in the cover to lie adjacent an end segment of the rotor in use regardless of the rotor width.
