Abstract

Abstract A mounting assembly for attaching a material treating blade to a vehicle such as a tractor which provides a material treating blade which is adjustable in height and the cutting angle of which is adjustable in three planes so that it is better adapted to grading, shaping and plowing soil and snow surfaces and to developing desired grades in movable matter. The assembly comprises first frame means for attachment to a vehicle, second frame means extending forwardly from the first frame means, first pivot means for securing one end of the second frame means to the first frame means for movement about an axis which is substantially horizontal and substantially normal to the longitudinal centerline of the second frame means when viewed from the top, first double acting hydraulic motor means pivotally connected between the first and second frame means for moving the second frame means about the first pivot means, third frame means adjacent to the forward end of the second frame means, second pivot means for securing the third frame means to the second frame means for movement about an axis which is substantially vertical and substantially normal to the longitudinal centerline of the second frame means when viewed from the side, second double acting hydraulic motor means pivotally connected between the second and third frame means for moving the third frame means about the second pivot means, fourth frame means adjacent to the forward end of the third frame means, third pivot means for securing the fourth frame means to the third frame means for movement about an axis which is substantially horizontal and substantially normal to the longitudinal centerline of the third frame means when viewed from the top, third double acting hydraulic motor means pivotally connected between the first and fourth frame means for moving the fourth frame means about the third pivot means, fifth frame means adjacent to the forward end of the fourth frame means which is adapted to support a material treating blade, fourth pivot means for securing the fifth frame means to the fourth frame means for movement about an axis which is substantially horizontal and fourth double acting hydraulic motor means pivotally connected between the fourth and fifth frame means for moving the fifth frame means about the fourth pivot means.
