  • Patent number: 4798011
    Abstract: A tractor side blade mount includes a control member, a blade holding bracket, a blade, a joint member for mounting the blade on the blade holding bracket, and a pair of hydraulically actuated arms for independently positioning the control member and the bracket. As a result of selected positioning of the control member and the bracket, the blade, which is mounted at one end of the bracket, may take up various angles, heights and lateral displacements with respect to the body of the tractor. The versatility in the movement of the blade results in an increased capability to grade earth, scrape dirt, or dig trenches alongside structures and in areas which would otherwise be out of reach of a conventionally equipped tractor.
