agricultural engineering. SUBSTANCE: general-purpose machine has frame made in the form of bar carrying (2n+1) guides, where n=1,2... of guides mounted perpendicular to bar longitudinal axis and adapted for displacement along bar. Double-level rippers are mounted on even guides for displacement in vertical plane. Rippers are made in the form of tine with pointed tip having curvature oriented in direction of movement of tillage tool. Flat hoe is located in ripper tine at side reverse to direction of movement of tillage tool. Flat hoe is positioned for displacement in vertical plane and changing angle of attack. Hillers are arranged rearward of double-level rippers for movement in vertical plane and rotation in longitudinal-vertical plane of tillage tool. Working tools are mounted on odd guides for movement along these guides. Odd guides are spring-loaded and mounted on frame through brackets so as to be rotated in longitudinal-vertical plane. Replaceable working tools are mounted on odd guides. Odd guides are longer than even guides. Tillage tool of such construction may be used in machines performing several agronomical operations for single pass. EFFECT: wider operational capabilities, provision for tillage of different soils for various crops, and increased efficiency. 4 cl, 10 dwg
