The main design feature of the tool is the presence of a hopper for fertilizers that are introduced into the soil at the same time as the seeds, but at a lower level, for the favorable development of the root system and growth. Bearingwheels cut a furrow of adjustable depth. Evenness of sowing is ensured by special single-level hoses equipped with the seeder.

The possibility of adjustments (sowing depth and row width) allows the sowing unit to be classified as universal. Functionality, durability and reliability are combined with simple operation.
