AGRICULTURAL TOOL FOR FORMING SOIL (VERSIONS) Russian patent published in 2014 - IPC A01B49/02 A01B21/00 

FIELD: agriculture.

SUBSTANCE: tool comprises a first row and a second row, located behind it, of earthmoving working bodies and at least one row of discs for forming soil. The adjacent working bodies of the first row are located at a first distance from each other, and the adjacent working bodies of the second row are located at a second distance from each other. The row of discs for forming soil is located behind the second row of earthmoving working bodies. The adjacent discs are located not at equal distance. The distance between the adjacent discs is greater or smaller depending on the fact whether the distance is located between the adjacent discs behind the working body of the first row or behind the working body of the second row. According to a second embodiment the tools of the earthmoving working bodies of the first and second rows are located at a predetermined distance from each other. The third embodiment of the tool provides location of the earthmoving working bodies of the first and second rows at equal distance, designed to form the first and second groups of recessions and groups of berms in the soil, at equal distance from each other. Each of the recesses in the second group of recesses is located approximately centrally of the corresponding berm from the group of berms and between the adjacent recesses of the first group of recesses. The second group of recesses is deeper than the first group of recesses. The discs for forming soil are designed for forming the first and second groups of recesses and berms to ensure the equal release of soil.

EFFECT: constructive implementation enables to ensure uniformity of location of recesses on the surface of the treated area, which enables to retain moisture in the soil and to facilitate sowing of seeds.
