TILLAGE TOOL Russian patent published in 2011 - IPC A01B13/08 

FIELD: agriculture.

SUBSTANCE: tool comprises a frame with inclined left-sided and right-sided working elements installed on it in pairs one after another. Working tools form transverse rows, where right-sided and left-sided inclined working elements are installed in pairs so that their inclined surfaces face towards each other. In the first transverse row there is one pair of working elements, in the subsequent one, excluding the last one, - two pairs of working tools. Working elements are arranged on the frame symmetrically relative to the longitudinal axis of the tool. In the last transverse row there is one right-sided tool and one left-sided working tool arranged so that their inclined surfaces are aligned in direction away from the longitudinal axis of the tool.

EFFECT: structural design will make it possible to improve loosening ability of the tool.
