ABSTRACT:
Apparatus to clean out a culvert used under a road where an open ditch intersects the road to break up and remove the dirt and debris which has settled within the culvert. The device comprises three equally spaced arms having a recess formed in the central portion thereof to reduce the surface area of the arms and a downwardly extending rudder formed in the central portion thereof to aid in breaking up the center of the bottom portion of the dirt within the culvert. The disc may be removeably attached to the device such that after the dirt is broken up, the disc is used to pull the dirt from the culvert. The device is pulled from the upper portion of the end closest to the direction of travel by a cable attached thereto which is extended through the culvert.
