This design will allow you to increase productivity by individual selection of row spacing for specific cultures and working conditions, to increase the efficiency of fertilizers through simultaneous application of sowing and primary doses; increase the crop yield in a result oriented basic fertilizer placement relative to the root system.

Disc seeding section operates as follows. When lowering the e in the first operating position of the Central knife 4, then hoe 5 and the rack 6 are immersed in the soil. Central knife 4 cuts of crop residues and roots of weeds. Central knife 4 and hour-TakeProfit 6 form a gap where toolprovider 6 enters the main dose of mineral fertilizers, which provides power to the two rows of crops (Fig.1, figs.2, figs.3, Fig.4).

Hoe 5 cuts and loosens the soil to a depth of sowing. Sowing disc blades 14 mounted at an angle to the direction of movement, are tight Lancet paw 5 box and create a furrow where twoseparate 16 serves seed and starter fertilizer.

The driving twoseparate 16 soil is excluded due to the fact that their length is less than the radius of the circular knives 14 and the ends of twoseparate are above the level of the soil, and the seeds and starter fertilizer placed in the furrow formed by the disc blades.

Due to the fact that the axis 13 is tilted back at an angle not exceeding 10° installed on them sown disc blades 14 move cut Lancet paw 5 soil towards each other and form a furrow where twoseparate 16 fall seeds and fertilizers. After the passage of the seed disk knives 14 soil shifted them to the center, occupies its original position, closing his educated slit, then the soil is compacted by the roller 1.

The contact force of the rink 17 to the soil is controlled by means of an adjusting screw 20 in contact with the bracket 19, and the spring 21.

Changing the seeding depth is achieved by varying the distance between the frame of the planter and the soil surface. Stabilization of planting depth on the finish soils provide the roller 17.

Changing the width of the aisle, in other words the distance between the movement trajectories of the left and right seed disk knives, provide by screwing or unscrewing the screws 9. In the result of interaction between the stops 10 with the annular grooves of the screws 9 carry out a longitudinal movement of the bracket 8 in the sleeve 7, and together with them and slotted bushing 11, the fingers 12, the axis 13, the brackets 15, twoseparate 16 and sowing disc blades 14.

Changing the angle of attack of cultivated circular knives carried out by moving the fingers with splined ends 12 in the slotted bushings 11.

To do this, hold the unfixing slotted bushing 11 with the fingers 12 with slotted ends. By moving up the sowing disc blades 14 with the axis 13 and the fingers 12 with splined ends are removed from the engagement slots, perform the rotation of the seed disk knives, axes and fingers slotted ends at the required angles, then perform the reverse action and impose the splines engage, commit the slot is wow connection.

Moreover, the angle of attack of the seed circular knife mounted on the end of the l-shaped stand 1 must be less than that of the seed disk knife 14, which is located closer to the sleeve 2 mounted on the upper end of the l-shaped rack 1.

The presence of the sleeve 2, whereby the disk sowing section is attached to the frame of the planter, eliminates damage to the Central circular knife 4 and the sowing disc blades 14 when moving the machine along a curved path.
