Abstract: A stinger bit on a bulldozer blade which is retractable to a point where its cutting edge aligns with the cutting edges of bits on opposite sides of the stinger bit so that the bits combine to provide what is in effect a straight cutting edge on a conventional bulldozer and particularly, a support and adjusting means for such a bit which is simple and compact.

Abstract: A mounting assembly providing for tilt adjustment of a bulldozer blade. The blade is pivotally supported by a pair of push arms. Motor means are pivotally interconnected between the respective push arms and the blade for adjusting blade pitch with one of the motor means being connected with the blade by means of a pivotal link. The blade is tilted by additional motor means interconnected between the blade and the link.

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.
