Abstract: An improved hydraulic cylinder construction having a feature thereon facilitating operative connection with a service kit to enable a quick and injury free removal thereof from a location whereat the hydraulic cylinder is spring biased in a shock absorber installation, particularly for use in a scraper blade mounting assembly.

Abstract: A road and/or airport runway scraping blade for use with a ground supported vehicle, which scraping blade includes a frame for attaching the scraping blade to the vehicle. The scraping blade has a front facing side, a rearward facing side, a top edge and a bottom edge, both edges extending laterally of a longitudinal axis of the vehicle when coupled to the vehicle. Coupling structure is provided for facilitating a coupling of the frame to the vehicle with the rearward facing side facing the rear of the vehicle. An elongated conduit and a fastening structure is provided for fastening the conduit to the rearward facing side of the blade intermediate the coupling structure and the bottom edge of the blade. A longitudinal axis of the conduit extends generally parallel to the lower edge. A plurality of laterally spaced spray nozzles are provided and are oriented along a length of the conduit and communicating with an interior of the conduit.
