Abstract : A low ground pressure (LGP) D4 Series D snow tractor was fabricated. The design objective is a tractor with less weight than previous LGP D4's. Although the basic tractor is heavier than previous models, the modified version will be about 1250 pounds lighter than D4C snow tractors, because the track shoes are being made from aluminum extrusions instead of the usual rolled steel section, and the allowable ground bearing pressure has been raised to 4.5 psi. Therefore, the track shoes are being made narrower, the track gauge has been reduced, and other components of the track system are being made lighter. (Author)
