Abstract
A hydraulically controlled bulldozer-blade attachment, particularly for application to an endless track tractor, exhibits, with a view to an improved versatility of use and a better adaptability to the various ground outlines, two half-blades which are linked to a liftable and depressable intermediate frame, the linking axes of the half-blades being at a backward incline relative to the vertical line with reference to the advance direction and each half-blade being controllable by a double-acting jack of its own. At their ends, the half-blades have sloping extensions which can be oriented about horizontal axes arranged in the direction of advance as controlled by double-acting jacks.
