The ripper working bodies are made in the form of spherical discs. The discs are mounted with an angle of attack in front of the rotor teeth and are facing with the convex to the longitudinal axis of the subsoil cultivator. The diameter of the rotor is at least one and a half times greater than the diameter of the discs. The discs are arranged above the lower line of the rotor body of revolution by an amount exceeding not less than half the radius of the disc. The devices for connection of the discs with the frame are made with elastic elements. The compactor is made with adjustable limitation of lifting height. The rotor teeth are provided with replaceable cutting devices. The discs are made adjustable in height and fixed on the spring-loaded or spring racks.
