FIELD: agricultural engineering. SUBSTANCE: tillage tool has working device 1 mounted on shank 2. Handle 3 and bracket 4 are attached to shank 2. Tie-rod is pivotally attached on bracket 4. Supporting member 8 is fastened on tie-rod end. Tie-rod has two pipe cuts 5 and 6 of different diameters and lengths. Pipe cut 5 is positioned within pipe cut 6 and fixed there by retainer 7 inserted into openings drilled in pipe cuts. When working tool penetrates into soil, tillage is performed by putting leg on supporting platform 9 and moving shank 2 for certain distance toward operator to zone behind shank 2, with following advancement of working tool to perform required operation. Upon cutting of furrow, working tool is turned through 180 deg to cut second furrow. Working tool is turned through 180 deg. Pipe cuts are detached one from another and pipe cut 5 is rotated relative to pipe cut 6 through 180 deg so that stop is positioned on untilled soil portion. Pipe cuts are fixed and furrow is cut. Pipe cuts are rotated one relative to another upon termination of cutting of second furrow prior to cutting of each subsequent furrow. EFFECT: increased efficiency, convenient operation and reduced labor intensity. 3 dwg
