PLOW Russian patent published in 2007 - IPC A01B17/00 A01B49/02 

FIELD: agricultural engineering, in particular, tillage and preparing of soil for sowing procedure.

SUBSTANCE: plow has frame, disks, working tool designed for rotating and placing of soil layer into furrow and provided with helical working surface, and mellower. Shaft with corrugated disks and mud scrapers is mounted on tines on frame. Working tool is made in the form of half-screw whose inner side is extending centrally of horizontal straight line from leading end to working tool end and outer helical working surface terminates in shank beveled at an acute angle to horizontal plane. Mellower attached to front side of working tool is made in the form of hoe. Replaceable harrows joined to shank are comprised of plates beveled at an acute angle on their front sides. Working tools with right-handed and left-handed direction of rotation of ground are alternatively mounted on frame. Supporting compaction roller with mud scraper is mounted rearward of frame on tines. Mounted on frame are also shaft height adjustment mechanism and supporting roller height adjustment mechanism for adjusting height of roller and supporting mechanism relative to frame.

EFFECT: improved quality of soil tillage, reduced erosion processes and increased efficiency in weed controlling.
