UPS-8 seeder, VESTA-8, Ups8 seeder, Supn seeder, Kirovohrad region.

To create a uniform vacuum, necessary during sowing of heavy seeds of leguminous crops (soy, etc.), the fanseeders is equipped with an additional air duct that provides stabilization air flow along the entire length of the receiver of the seeder and guarantees uniform sowing on each section.

There is a flap on the fan to regulate the rarefied air flow.

The sowing section of the Tru-Vi design with a rolling system and a wavy slotted disc is used on the seeder. The seeding device is built into the frame of the seeding section, which excludes the influence of loads from the design elements of the working bodies. Screw adjustment of the deepening of the sowing section reduces labor costs during adjustment.

V-подобный каток, which has an adjustable width of rolling and compaction of the soil, ensures the pulling of moisture into the sowing area, pressing the seeds to the soil, while leaving a non-compacted layer of soil above the seed material, which contributes to earlier and friendly germination of seeds and increased productivity.(//tractor-service.com)

For work on untreated soil, the sowing section is equipped with a special wavy disc (дисковый knife), which cuts through the soil for the subsequent formation of the seed bed. When entering the soil, the waves on the disc are located perpendicular to the soil surface, which maximizes the cutting ability at the minimum required pressure. When leaving the soil, the waves on the disc are arranged parallel to the surface, which prevents wet soil from sticking. The wavy disc is characterized by the best ability to loosen the soil with minimal effort to press the harvest residues into the ground at a speed of 5.5 to 12.0 km/h. Thanks to such a design of the disc, a strip of loosened soil is formed directly in front of the sowing section.

A fat seeding device is added as an option, which consists of fat seeding devices, fat coulters, gearboxes and a drive. The design of the seeder allows, if necessary, to conveniently and quickly remove and install the device.

The amount of seeds that enters the seeding chamber from the hopper is regulated by the shutter. The comb-type dropper ensures accurate single-seed sowing. A harrow is installed on the sowing disk, which promotes better suction of seeds to the holes of the disk and improves the quality of sowing.

An unloading hatch is provided for quick removal of seeds from the chamber of the seeding device.
