“…In this case, the following assumptions and initial conditions are accepted. A sectional type pneumatic seeder with installed vertical-disk vacuum type sowing devices and the use of a mechanical sowing device for excess seeds is considered [5]. maintenance of the Seeder is carried out on a special site with a flat hard surface.…”

The level of preparation of a row seeder for work and its adaptability to adjustments and settings affects the efficiency of sowing. Analysis of the designs of modern row seeders shows that after-sales service remains a reserve for improving the efficiency of their use, and, therefore, increasing the agricultural crop yields. However, the technologies for the preparation and adjustment row seeders remain poorly understood, and the search for ways to reduce the complexity of maintenance for sowing units is an urgent task. The aim of the study is to build a mathematical model of the technology for checking, adjusting and tuning a row seeder on the basis of graph theory, determining a way to reduce the complexity of servicing maintenance a row seeder in preparation for sowing and justifying a rational way of organizing the seeder setting. Taking into account a number of assumptions and initial conditions, a list of operations for adjusting and setting the seeder is developed. A digraph of a row seeder preparation technology is constructed, which displays the sequence and relationship of the operations of preparation, adjusting and sitting its nodes and mechanisms. The critical path with the greatest time spent on seeder maintenance is determined. The methods for reducing the complexity of maintenance of a row seeder were established and it is recommended that further modernization of the units and mechanisms of the seeder by indicators in terms of suitability for verification, adjustment and setup. The methods of preparing the seeder for work by one performer are considered. The influence of economic factors on the number of performers during maintenance of the seeder before sowing is shown.

“…Based on the analysis of patents and literature sources [1,6,7,11,12] there are two main types of distribution devices of pneumatic grain seeders: vertical (Figure 2 The vertical distribution system consists of a pneumatic pipe that rotates at right angles and a head that is a body of rotation with radial discharge pipes and a reflective surface inside. Vertical seed dispensers usually differ in the shape of the reflecting surface of the feed column.…”
