SUBSTANCE: compacting-leveling system has tine and rollers mounted on tine. Each of said rollers has disks with bars. Tine is equipped with spring-loaded lever mounted thereon by means of pivot joint, with axis of said lever being positioned at center of gravity of said system, in parallel with axes of rotation of rollers. One of said rollers is fixed on one arm of lever and other roller is fixed on other arm of lever. Bars of one roller have C-shaped section with convexity oriented toward roller axis and are provided with teeth fixed thereto. Bars of other roller have semi-circular section with convexity oriented away from axis of roller and are fixed at an angle to radius of roller.
