SUBSTANCE: working body for subsurface soil treatment contains the disposed hard-alloy coating applied in the form of rollers with the layer thickness of 2-4 mm. The first rollers are arranged on the front surface in the fore part of the working body and are arranged symmetrically with respect to the symmetry axis of the working body. The first roller closest to the fore part is arranged from the edge of one cutting edge to the edge of the other cutting edge of the toe of the working body. The second rollers are arranged on the front surface near the cutting edges at an angle to the cutting edges at the same distance from each other, with the length of the rollers from the edge of the cutting edges not more than the distance therebetween. The second rollers nearest to the fore part are located at an equal distance between the first rollers. The working body additionally has the third rollers arranged at the rear surface adjacent to the cutting edges at an angle to the cutting edges at an equal distance from each other. The first, second and third rollers are made arcuate, the concave side of their side surfaces faces in the movement direction of the working body.
