  • Patent number: 3974881
    Abstract: Bulldozer blade mounting including two push arms swingably mounted on the opposite sides of a tractor at their proximal ends, a blade connected to the distal ends of the arms, a tilt brace connected between the top of the respective arm and the upper side of the back of the blade, and a pair of diagonal braces each swingably connected to the respective arm and extending inwardly toward each other and connected at its inner end together by a universal pivotable means. The location of the universal pivotable means is so selected that it lies at a level higher than the plane including the pivotable connection of the respective diagonal braces to the arms. This construction eliminates the need for slidable and pivotable connection between the diagonal braces and the loose connection of the slidable and pivotable connection to the back of the blade thereby permitting the construction and assembly to be simple and the production cost to be low while proper operation of the blade mounting is insured.
