The seeding unit is one of the most important parts of a grain seeder, as it not only affects the distribution of seed per unit area, but also the deviation from the specified seeding rate, as well as the crushing of the seed. When examining various types of seed wheel designs, it can be concluded that they mostly have sectional rollers, the grooves of which are straight and staggered on the surfaces of the sectional rollers. The disadvantages of such seeding machines include deviation from the specified seeding rate, unsatisfactory distribution of seeds per unit area, as the location of grooves on the surface of the sectional roller is staggered, resulting in seed rolls from the edges of the sectional roller and falls on the adjacent sections of the sectional roller. The article presents the design and principle of operation of the developed seeding unit of a grain seeder with inclined ribs and grooves and sectional roller groove dividers. When using it, deviation from the set seeding rate, unsatisfactory spreading of seeds per unit area, crushing of seeds are reduced. All this improves the quality of seed sowing.
