The furrow opener coulter is the most commonly used on precision seed drills. It is also used on the seeding section of the seed drill UPS 12. Due to such a design, the coulter guarantees the formation of a compacted seed bed, as well as the walls of the furrow, which help to pull the capillary moisture to seeds. But the main disadvantage of this design is the seeds redistribution along the furrow sole as the result of the displaced topsoil effect, which is shedded behind the rear wall of coulter side panels. There is proposed an improved design of the UPS 12 seed drill coulter that is equipped with a disk seedbed former and eliminates the above-mentioned disadvantage. Under laboratory conditions, there were conducted comparative experimental researches of series-produced and advanced coulters. The obtained tests' results made it possible to ascertain the advantage, with regard to the performance quality of technological process, of the coulter with a disk seedbed former.
