FIELD: agricultural engineering, in particular, technique for soil covering during tillage. ^ SUBSTANCE: ridging roll has frame, shaft and spherical disks loosely mounted on shaft. Rings are positioned between disks for free rotation and altering distance between said rings. Roll frame is made composite so that space between its longitudinal beams may be adjusted. Longitudinal beams are connected with one another by means of adjusting mechanism. Rings have diameter reducing from outer rings to intermediate ring. Spherical disks are positioned on outer side of frame longitudinal beams so that angle of positioning of said beams relative to advancement direction may be changed and said beams may be fixed in predetermined position. Flexible members are located between rings. ^ EFFECT: improved quality of formation of soil ridge and wider operational capabilities of ridging roll. ^ 2 dwg |
