Universal pneumatic seeders of theUPS-8 model series are intended forprecise sowing calibrated seeds of corn, sunflower, castor, sorghum, soybeans, as well as seeds of fodder beans, beans, lupine with simultaneous application of granular mineral fertilizers separately from the seeds and rolling of the soil in rows. It is also possible to sow uncalibrated seeds, but in this case the accuracy will directly depend on the difference in size and the degree of damage to the seed material.Seeders of precise sowing ensure sowing to the final density, excluding the use of manual labor during the formation of the necessary interval between plants. Planters of the UPS-8 model series are mounted and aggregated with tractors from 80 hp. Due to the location of the axis of the support-drive wheels on the same line with the grain coulters, simultaneous copying of the field relief is achieved by both the frame and the sowing section. The low location of the seeding device ensures the minimum distance from the point of dropping the seeds to the seed bed and guarantees the accuracy of seed placement in the row.
