  • Patent number: 6551031
    Abstract: An erosion fence installation attachment for ditchers and trenchers that is short in length and articulated to pivot in pitch and yaw so as to permit the attachment to follow a ditcher through gullies over mounds and around arcs. The attachment is provided with a barrier material roll unwind, a resilient guide that guides the barrier material into a ditch formed by the ditcher so that the barrier material is pressed against the sides and bottom of the ditch to form an open channel, a first ditch fill disk that pushes fill material into the ditch and into the channel formed in the barrier material, a second ditch fill disk that pushes fill material from the opposite side of the ditch and onto and over the barrier material on that side of the ditch to form a wrap around the fill material deposited by the first fill disk so as to form an elongate anchoring pouch filled with fill material along the bottom of the ditch.

  • Patent number: 6203244
    Abstract: A screeding attachment for an industrial utility vehicle. The screed and vehicle in combination provide a low cost, maneuverable and versatile screeding unit for screeding small and medium size pavements such as driveways, sidewalks, slabs and surfaces inside buildings and the like. A see-through frame supported on castered wheels and a see-through distribution and deposition system for metering and depositing paving materials in the path of a grooved cylindrical screed provide an apparatus for continuously laying a screeded slab under the direct observation of an operator in the industrial utility vehicle.
