Abstract

Planing apparatus is disclosed having a rotatable cutting drum comprising a central, rotatable support, a plurality of secondary supports spaced around the central support and in parallel relationship thereto, and a plurality of apertured cutting members mounted on each secondary support and axially spaced apart. The spaces between the cutting members on one of the secondary supports is bridged or almost bridged when viewed in a direction normal to the axis of the drum by the cutting members on one or more of the other secondary supports. The drum is housed for rotation in a base structure having rear wheels and front wheels which can be displaced vertically to adjust the depth to which a surface, e.g. a road surface, is to be planed. The drum and wheels are driven by a motor supported on the base structure. Various different types of cutting members are disclosed.
