FIELD: agriculture; machine building.

SUBSTANCE: invention relates to the field of agricultural machine building. Disk cultivator contains a frame with racks. Pair of flat and small diameter discs is fixed through the hubs to the posts. Flat disks are inclined to each other in the vertical and horizontal planes, and also equipped with fixed blades in the form of a logarithmic curve from the inside. Ratio of the diameters of flat disks is determined by the expression d=D-2a, where d is the diameter of the small disk, D is the diameter of the large disk, a – the depth of immersion of a large disk in the soil. Small disk is offset relative to the large disk relative to the vertical axis, and also against the movement of the cultivator by a distance L, the value thereof is determined by the formula L=D+a.

EFFECT: reduced energy intensity of tillage, stable depth of tillage and increased degree of crumbling.
