FIELD: agricultural engineering. SUBSTANCE: digging tool has main frame, movable frame, digging share pivotally connected to main frame, and flexible member such as spring. Movable frame is mounted on main frame for movement relative thereto. Digging share is positioned so as to act upon movable frame. Share end opposed to cutting edge is connected to frame through rocker arm, which is arranged in inclined position and may be rotated during advancement of digging tool. Such construction allows digging depth to be adjusted depending on relief of compacted soil bed in ridge. EFFECT: increased efficiency and simplified construction. 1 dwg
