FIELD: agricultural engineering.

SUBSTANCE: tillage tool has hitch tongue, carrier wheels, frame, paired disks on spring-type C-shaped tines, and mellowing devices with hoes. Hoes of mellowing devices are equipped with double-sided three-faced wedges. Wedge faces are equipped with semi-spherical projections spaced apart from one another by distance ▵_l=▵_tr, where ▵_l is longitudinal distance between semi-spherical projections, ▵_tr is transverse distance between semi-spherical projections. Paired rollers positioned behind mellowing device have different diameters. Diameter d_f of front roller is greater than diameter d_r of rear roller. Rear and front rollers are interconnected by means of torsions and are connected with frame through pivot joint, bracket, pressing plank and spring.
