  • Patent number: 5810097
    Abstract: An attachment system for mounting road-maintenance equipment on a vehicle such as a motor grader includes a frame for mounting on the nose plate of the vehicle to support the conditioning equipment forwardly and partly outboard of the vehicle. The system includes pivotal attachment mounts for the front and rear ends of a draft frame of the conditioning equipment together with a strut for supporting the draft frame at a desired orientation during operation, and for raising the draft frame and surface conditioning equipment to a retracted position when not in use. A mast on the attachment system frame directs a cable to the rear end of the draft frame to effect raising movement of the latter to the transport position.
