Abstract
A bulldozer assembly has a swivel connection between blade and C-frame for permitting both angling and tilting motions of the former relative to the latter. The swivel connection comprises a swivel block mounted centrally astride the front end of the frame for pivotal or tilting motion relative to same in its lateral direction about a horizontal axis. The swivel block is hingedly jointed to the blade so that the latter may be tilted simultaneously with the block but free to angle relative to same about a normally vertical axis. A tilt cylinder is operatively connected between frame and swivel block, and a pair of laterally spaced angle cylinders between frame and blade.
