To the History of Agricultural Machinery Development

Technological and technical modernization of separate elements of seeding machinery having a decisive influence on quality of cultivated smallseed crops, including flax, makes it possible to find directions to study a complex multilevel system of functioning, both the sowing device and the combined leveler, and seeders on the whole.The solution of this problem is possible on the basis of the system approach, by mathematical modeling and conducting appropriate laboratory and field tests.In this regard, the optimization of parameters and operating modes of separate seeder units aimed at better quality of the sowing system, reducing the en-ergy intensity of the process, emphasize the relevance of the selected topics.The paper describes the tasks to be solved: analysis of existing seeders for sowing flax seeds, working organs for seed leveling and seeding, mathematical modeling of the system «seeds -sowing device -seed pipe -leveler -coulter», theoretical studies of the main parameters and operating modes of the construction, finding out qualitative indicators of the operation of the experimental seeder in combination with the levelercoulter in laboratory and field conditions, economic evaluation of the production test results to be implemented.
