High-precision seeders provide for the final seeding density, excluding the use of manual labor in the formation of the desired spacing between plants. Pneumatic sowing units of the precision seeders reduce the percentage of seed crushing 10 times compared to mechanical sowing units. All drive shafts of grain and fertilizer sowing units are mounted on ball bearings. Due to the location of the axis of support drive wheels in line with the grain openers, we have achieved synchronous field contouring for both sowing frame and sowing section configurations.
