  • C-frame assembly for bulldozer
    Patent number: 4167979
    Abstract: In an angled bulldozer blade and tractor assembly, a C-frame is constructed in two parts with interfitting elements at the midportion of the C-frame which are held together by axially aligned bearings or sleeves. A blade pivoting pin extends through the midportion of the interfitting elements with the axis of the pin lying transverse to the axis of the aligned bearings or sleeves. Parts of the interfitting elements of the connection are shaped to permit relative rotation between the two halves of the C-frame, particularly for use during storage and shipment of the C-frame.
