FIELD: earth-moving machines. SUBSTANCE: earth- moving machine has self-propelled chassis 7 and turning blade 8 connected to it. Blade 8 is connected with chassis 7 by means of six rods 1-6 located between blade and chassis. Directions of six rods are not crossed by one straight line. Each rod 1-6 is joined with blade 8 or chassis 7 by means of special articulated joint 11. At least two rods 1-6 are nonparallel. Mounted on blade and chassis are at least three rod articulated joints not lying on one straight line. At least three rods are made of parts relatively moved in longitudinal direction. Relatively moved in longitudinal direction parts of rods 1-6 are made in form of hydraulic cylinders. In operation earth-moving machine may vary angle of blade positioning in plan, angle of cutting of blade cutter, angle of blade cross cant, and may move blade to the right and to the left relative to chassis, and lower and raise blade.
