We have special demands to the planting of the tilled crops. Unlike grain crops, the tilled crops are sowed in a line with the certain step, which permits to provide the rational placing of the plants on the feeding areas. Due to this, the necessary conditions were made for their further growth and getting of big crops. For planting of the tilled crops all over the world people apply pneumatic precision drills with vacuum seed-sowing mechanisms and the quality of realization of the operation depends on their work greatly. The process of work of the vacuum seed-sowing mechanism can be divided on basic stage, the process of catching a single seed and carrying it out of the layer of the others with the drawing hole is the most responsible among them. The analyses of the work which has been done let conclude that the influence of the agitator on the layer of the seeds in the zone of their catching with the drawing holes increases the efficiency of this process. With an aim of the activation of the working process of the central agitator the authors offer to make its blades in such a way that their working sides would be turned in the direction of rotation of the agitator and the plane of the feed disk. All this let use the agitator not only for activation of the layer of seeds but for their push to the drawing holes of the feed disk. The proof of the offered construction is presented in the article, the results of the comparative experimental researches of the serial and the modernized vacuum seed-sowing mechanisms and the analyses of obtained data are shown, conclusions have been formulated
