The moldboard 15 is made flat and is mounted on the semi-axis with the ability to change its position on height along the rack with respect to the cutting edges of the A-hoe blade and the impinging angle in the horizontal plane, as well as fixing in the desired position. The moldboards 15 of each pair of the ridge formers 4 are mounted symmetrically with respect to the line of the seeds sown at an angle which aperture is directed towards the ridge drill movement. The packing wheels 3 comprise a frame, spherical discs 25, packing rings 29, an axis 28, a bar 30 with a spring 31, and located behind the ridge formers 4.
