  • Publication number: 20080100125
    Abstract: An asphalt cutter that includes a hollow cylindrical body with a plurality of longitudinally aligned, curved teeth evenly spaced apart along the body's lower perimeter edge. The teeth are curved in a forward direction of the normal rotation of the body during use with a hardened carbide edge formed thereon. The teeth are slightly wider in cross-section than the side wall of the cylindrical body. During use, a circular gap is formed in the asphalt which enables a center plug formed therein to be easily removed by utility workers. Attached to the top end of the cylindrical body is a longitudinally aligned hollow neck with a top opening. During assembly, the drive shaft on a hydraulic motor attached to the articulating boom is inserted into the neck. A bolt connects the neck and drive shaft together. In the preferred embodiment, an optional elongated guide flag is longitudinally aligned with the cutter.
