TILLAGER Russian patent published in 2009 - IPC A01B49/02 

FIELD: agriculture.

SUBSTANCE: invention is used for tillage implying undercutting topsoil without turning over the layer and with simultaneously crushing the tilled soil layer. The tillager comprises flat hoe tools, front and rear packing wheel sections mounted next to the tools. Packing wheel sections are made as a spiral connected to the rotation axis by bushings sliding along the axis and connected to the spiral turn by a spoke. Axial deflection of the sliding bushings can help altering the spiral pitch at the packing wheel sections. The packing wheel sections are mounted at an angle to the motion line, and spirals of the front and rear packing wheel sections are fitted with counter winding.

EFFECT: making solid packed soil layer under various soil-climatic conditions producing mulching layer from soil, removed weeds and stubbles, providing for the packing wheel to be self-purified and reduce soil more qualitatively.
