Seeder of exact seeding SPM-8 is used for dotted sowing of calibrated and non-calibrated seeds of corn, sunflower, soybeans with simultaneous application of mineral fertilizers and soil packing in the rows. For aggregation, it is recommended to use the tractor traction class of 2.0 The accuracy of seed distribution is achieved through the use of American planters "precision planting" vacuum seed metering system. Sowing the seeds of a predetermined depth is provided by the double disc coulters with double wheels, Cams. Rolling-crops made v-shaped press wheels with adjustable down-force. To work on technology no-till seed drill is equipped with a turbo wavy disc, which prepares the ground and clean seedbed from crop residues. Seeder SPM-8 is equipped with a drilling control system and reliably monitor crop performance. Fertilization occurs through a double disc opener, which can be adjusted to the desired depth and distance from the seed row. The seeder is used in all soil-climatic zones, excluding mountain agriculture. Comes with discs for seeding maize and sunflower.
