Background. Improving the manufacturability of products at the stages of design and technological preparation of production determines the effectiveness of all subsequent actions, both in the development of technological processes and the functioning of machining systems. Changing the design of the assembly based on an assessment of the performance characteristics of the product is the most optimal way to improve manufacturability without reducing the consumer properties of the product. The purpose of the work is to justify the modernization of the coulter unit of the seeder to improve performance and manufacturability. Materials and methods. Experimental studies of a serial assembly unit according to the classical method. Results. A technique has been developed to ensure the functional characteristics of the coulter unit and the required characteristics of the elastic elements of the structure have been determined. Conclusions. Quantitative assessment of the elastic characteristics of deformable elements requires clarification of the initial data, which is a variable value in the conditions of mass production. In accordance with this, the change in the design of the coulter and the organization of normalized input control made it possible to ensure the quality characteristics of the seeder coulter.
