Abstract
A device for cutting through pavement in order to remove a manhole casting during the repaving of a road surface so that the manhole casting may be raised or lowered to correspond with the elevation of the new road surface. The device is mounted on a conventional road grader that has been modified to accommodate the device and is positioned over the manhole casting so that the existing pavement and cement may be cut from the road surface and the manhole casting removed to permit bricks to be laid on or removed from the manhole so as to raise or lower the manhole so that the manhole casting's height will correspond with the elevation of the new road surface.
