New designs of tillage and seeding equipment are presented. Technological and technical deficiencies of the existing working bodies for surface tillage and sowing techniques of row crops are noted. To eliminate the shortcomings, new universal working bodies of tillage and sowing units have been proposed, which provide for the mechanization and automation of working processes of tillage and seeding of various row crops. Their technological and technical advantages over the existing traditional working bodies are given. The technical characteristics of the new working bodies are presented, which allow to simultaneously perform four operations: cultivation, fissure, seeding and leveling the field surface. Execution of the sieve in the form of two discs with rollers on its inner surface allows cutting a slit along the sides from the vertical axis of seed placement, at a depth of almost twice the sowing depth to improve the water-air regime, with simultaneous compaction of the soil by the rollers. The final operation to level the soil across the entire width of the cultivator's paw grip is carried out by embedding a train. Also presented is the design of a modernized pneumatic sowing unit for various sowing methods, ensuring the simultaneous sowing of seeds of several types of row crops with their placement at different planting depth in accordance with agrotechnical requirements
