摘要：
A useful model refers to agricultural machinery, in particular to soil cultivators for surface tillage.Combined tiller unit includes a frame on which vertical stands with axes are mounted and spherical disks with adjustable angle of attack, rotary discs mounted on rotational axes, are mounted. Behind the unit there are transport-technological wheels. On the periphery of each spherical disk are executed figured notches in the form of a semicircle, and the cutting edge of spherical disks is sharpened. With the rear part of the frame of the unit is fixed a roller attachment containing a frame, grinding and packing rollers, bars with springs. The grinding wheel contains an axis and disc rippers. Disc rippers are installed on the axis of the crushing rink at regular intervals, and on the periphery of the disc rippers, figured grooves are made. The vertices, located between the figured notches, They are triangular and directed in different directions from the geometrical axis of rotation of the disc rippers. The rolling roller contains an axle, side and intermediate discs. Side and intermediate discs are installed on the horizontal axis at regular intervals in the horizontal plane. Along the circumference of the lateral and intermediate discs of the compacting roller with an equal angular step, loosening elements are installed, in the cross section having the shape of an equilateral triangle, the ripping elements being rigidly fixed along the periphery of the lateral and intermediate disks, and the sharp peaks of the ripping elements are directed in different directions from the geometric axis of rotation of the packing roller. Side and intermediate discs are installed on the horizontal axis at regular intervals in the horizontal plane. Along the circumference of the lateral and intermediate discs of the compacting roller with an equal angular step, loosening elements are installed, in the cross section having the shape of an equilateral triangle, the ripping elements bei
