  • Patent number: 9139998
    Abstract: The present invention is directed to a culvert cleaning apparatus for attachment to a bucket of an earth moving machine. The culvert cleaning apparatus comprises a long shaft that has rotating arms attached to it. As the apparatus is inserted into a culvert and through a debris field the arms are pushed against the shaft to minimize the diameter of the apparatus. As the apparatus is removed from the culvert, the arms engage with debris, rotate outward to increase the functional diameter of the apparatus and pull/push debris out of the culvert.
