FIELD: agricultural engineering. SUBSTANCE: soil-cultivating aggregate has frame with side wings, longitudinal beams with posts, fastenings on different levels of front and rear working units, vertical post with struts, jaws to link aggregate with tractor, supporting wheels. Front flat-cutting working units are made in the form of detachable cantilevers, mounted on post, knives, holders of which are hinged to detachable cantilevers, and chisel, fixed on cantilever with bigger cutting angle, than one of knives. Noses of knives are set with clearance under side cuts of chisel. Rear flat-cutting working units are made in the form of paw with fingers, under wings of which cultivators, made as conical disks, are mounted with the help of detachable extensible cantilevers with retractable gears. Side wings of frame are made telescopic and linked with vertical post with the help of mounted between them adjustable braces. Extreme jaws, used to link aggregate to tractor, are made detachable. Wings of frame on longitudinal beams have cantilevers to fix supporting wheels behind posts of rear working units. EFFECT: soil cultivating aggregate is used in agriculture. 3 cl, 3 dwg
