APPARATUS FOR BASIC CULTIVATION OF SOIL Russian patent published in 2007 - IPC A01B49/02 

FIELD: agricultural engineering.

SUBSTANCE: apparatus has three-point mounting system, tubular attached frame, cultivation depth adjustment mechanism, and working tools mounted on frame. Cultivation depth adjustment mechanism has carrier wheels positioned at different levels. Working tools are made in the form of plated tines with A-hoes arranged in lower part of tines, at an angle thereto. A-hoes are arranged in tiers. Second tier A-hoes have width smaller than width of first tier A-hoes. Third tier A-hoes have width smaller than width of second tier A-hoes. First tier A-hoes are equipped with rigidity ribs formed as stirrers arranged at an angle to direction of advancement of apparatus. Housings with saws are mounted on tines of third tier hoes. Housings are coupled through bar to drive mechanism having electric engine, screw, two gears, crank, and connecting rod.
