FIELD: agriculture. ^ SUBSTANCE: outfit contains a frame, operating elements, sections of ring conic rollers, attached to the frame by spring loaded drawbars. The operating elements are mounted in a row or several rows and made in the form of A-hoe blade. The operating elements have a fertiliser incorporator and device for seeding designed for the A-hoe blades. Each A-hoe blade is connected with the frame by a parallel linkage with rigging screw and spring loaded drawbars. Two ring conic rollers supported on soil are attached to the spring loaded drawbar behind each A-hoe blade. One of the rollers is displaced leftward relative to the blade, and the second - rightward forming a lead angle. Two ring conic rollers are mounted in such a way that they can be vertically and horizontally adjusted relative to the A-hoe blade. A press wheel is fixed behind two ring conic rollers and mounted with possibility being vertically adjusted. All rollers are fixed in the section at lead angle. Each ring conic roller is fixed on its axis. ^ EFFECT: uniform seeding of grain crops with fertiliser distribution at the depth, saving of soil moisture, exception of weed wrapping over the axis of the ring conic rollers. ^ 4 cl, 4 dwg |
