• When planting, most planters coulters enter the ground from the top. They meet hard clods of soil, jump, changing the depth of planting seeds. Some seeds are thrown to the surface. As a result, the sowing germination, as well as yield, decreases. (Research purpose) To develop an innovative soil-cultivating pointed paw, eliminating the rejection of soil and the formation of unevenness of the surface, as well as increasing the productivity of the cultivator. (Materials and methods) The authors determined the setting parameters of the developed deflector pointed paw with the involvement of mathematical device and taking into account the requirements for the working bodies of soil-cultivating units. (Results and discussion) The authors developed an innovative deflector pointed paw. A triangular deflector was placed over the ploughshare. They determined the optimal angle of deflector inclination in the horizontal plane-15-25 degrees, and the height of the installation of the pointed paw over the blade- in 1.5 times above the depth of soil cultivation. It was found that the rear part of the deflector, which has a serrated shape and curved down, allows to grind the soil, forming a small-lumpy structure. It was shown that the soil, moving along the deflector, in collision with the curved part returns to the surface, closing and leveling the formed furrow. The triangular shape of the rack between the ploughshare and the deflector significantly reduces the clogging of coulters with plant residues. (Conclusions) The authors proved that the leveled soil surface with a finely lumpy structure of the top layer can be obtained using a deflector pointed paw, which eliminates the use of rollers. This reduces the material consumption of the cultivator, fuel consumption, and productivity increases by 50 percent as a result of increasing the speed of soil cultivation to 18 kilometers per hour.
