  • Patent number: 4782606
    Abstract: A method and apparatus are provided for more efficiently backfilling a ditch in the ground. The apparatus is comprised of a rigid compartment adapted to be pendantly supported by the dumping scoop of a front end loader vehicle. The compartment has an inclined floor and a closeable aperture located at the lowermost extremity of the floor. Backfill material dumped from the scoop falls into the compartment and is diverted horizontally a sufficient extent to enter the ditch. By virtue of the apparatus and its manner of association with the dumping scoop, the front end loader can fill the ditch merely by riding a continuous path parallel to the ditch.
