This article deals with the theoretical approach and design of a combined soil cultivation and seeding unit for implementation of the strip-till resource-saving technology (Strip-till). The relevance of the current research is connected with developing domestic machinery capable of combining operations of deep loosening, localized fertilizer application, and seeding in a single pass, as well as by the need to expand the application of this technology to cereal and leguminous crops. The object of the research was to develop a unit with a row spacing of 450 mm and a working strip width of 200–250 mm, possessing versatility and reduced draft resistance. The methodological framework comprised a system approach, methods of theoretical mechanics, strength of materials, and mathematical modeling, including finite element analysis. Parameters of a frame with a closed force contour were designed to promote rigidity and reliability, as well as working sections: a cutting disc, a row cleaner, a cultivator shank with an integrated fertilizer delivery tube, and a pressing roller. The proposed integration of the fertilizer delivery tube eliminates the need for a separate opener, thereby reducing metal consumption and energy requirements. A prototype four-row unit was developed with a working width of 1.8 m, a loosening depth of up to 300 mm, and an operating speed of 6-9 km/h. With the theoretical analysis it was noted that the draft resistance ranges from 9 to 14 kN, which enables hitching to tractors of traction classes 3-5. It was observed that the proposed design expands the technological capabilities of Strip-till, reduces production costs, and reduces anthropogenic load on the soil.
