Abstract: A mounting and control arrangement for supporting a bulldozer blade upon a tractor by means of a C-frame. The blade is centrally secured to the C-frame by a universal ball joint. Hydraulic angling jacks are interconnected between each leg of the C-frame and a guide member slidably mounted on a T-shaped bar respectively secured to each C-frame leg. A triangular brace supports each end of the blade and is secured to the respective guide members by a ball joint. The angling jacks are pivotally connected to the C-frame legs and the guide members by means of ball joints to reduce stresses with the pivotal connection between the angling jacks and the guide members preferably being a trunnion mounting having a pivot axis perpendicularly related to the axis of the pivot joint between each angling jack and the C-frame.
