Abstract

A cutting machine for cutting depressions in a road surface. The cutting machine includes a rotatable cutting drum connected with a drive device for rotating the cutting drum and an engaging device for moving the cutting drum out of and into contact with the road surface. The drive device includes a gear box with a flywheel located on the input side of the gear box and the cutting drum comprises a plurality of cutting teeth, the teeth removably retained to the cutting drum to effectively cut the road surface and includes a means for anchoring a tooth shank to a tooth holder permanently affixed to said cutting drum. A power unit that moves the cutting drum along the road surface is provided with a detector for continuously detecting a distance that the cutting drum is moved by the power unit and for generating a signal indicative of the distance moved. An electronic controller, responsive to the signal, electronically controls the engaging device so that the cutting drum moves out of and into contact with the road surface in accordance with the distance that the cutting drum moves along the road surface and a specified dimensional profile of the depressions which are stored in the electronic controller. The movement of the cutting drum cuts depressions in the road.
