FIELD: agriculture.
SUBSTANCE: invention relates to the field of agricultural machinery industry, in particular to tools for main deep subsurface tillage. The discovator comprises a hitch tongue (1), a frame, working elements. The frame consists of a middle section (2) and lateral sections (3) hingedly attached. On the frame the support wheels (4) with the depth adjustment mechanisms are mounted, working elements tiered fixed. In the upper tier the working elements in the form of spherical discs (5) and A-hoes (7) are fixed. In the lower tier the rippers (6) with a chisel are mounted. The spherical discs (5) are mounted in one row and are unfolded at an angle of attack in opposite directions symmetrically with respect to the centre. Each spherical disc (5) is fixed on the individual rack and is spring loaded relative to the frame and is located on the same axial line with the respective ripper (6) or an A-hoe (7).
EFFECT: constructive solution enables to reduce the metal consumption and to provide sustainability of operation of the working elements.
