SUBSTANCE: combined soil-cultivating unit comprises a frame (1), a hitch (2), support wheels (3), operating bodies (14) with brackets for their fastening (4). Mounting brackets (4) are made in the form of two plates parallel to each other, having four coaxial holes configured for installing bolts in them. The distance between the plates is equal to or greater than the thickness of the frame bars (1). On the outer surface of one of the plates, two mounting angles are installed configured for movement relative to this plate by a length equal to the double length of the slots with rounded edges, made on the parts of the mounting angles adjacent to the plate, adapted for installing plate bolts in them. In other parts of the mounting angles perpendicular to this plate, two holes of different diameters are made, which are coaxial with each other, respectively, configured for installing mounting and shear bolts in them.

EFFECT: simplified reconfiguration of the tillage unit.
