FIELD: earth moving machines.
SUBSTANCE: invention relates to earth moving machines, for example, bulldozers. Working element of the bulldozer contains a front plate, side walls and a cutting knife. In the upper part of blade (1) upper side wings (5) are fixed, and in the lower part, lower side wings (8) are hinged by levers (6) and hydraulic cylinders (7). Hydraulic cylinders are communicated via hydraulic control valve with pressure hydraulic line, hydraulic tank and hydraulic accumulator (13). When digging soil, lower side wings (8), partially balanced by hydraulic cylinders of drive (7), which are interconnected with hydraulic accumulator (13), slide along soil surface and prevent soil losses into side rollers. Front edges of side wings do not interact with soil and do not create additional resistance.
EFFECT: reduced resistance to digging and power consumption, reduced losses of soil from the drawing prism and increased efficiency.
