<p>LOW GROUND PRESSURE TRACK SHOE A low ground pressure track shoe includes a ground-engaging surface defined, in part, by downwardly converging arcuate surfaces having a radius of curvature, at various points along the length of the shoe, which is slightly less than the distance between the pivot connections of a track link with which the shoe is adapted for use. The ground-engaging surface has a central lowermost flat rectangular surface constituting approximately one-ninth of the vertically projected surface area of the shoe.</p> |
