Seeder mechanical grain SZM Nika-4, Kirovohradska reg.

Seeder "Nika-4" has two capacious hoppers - 920 l for seeds and 350 l for fertilizer, which creates prerequisites for high productivity and lower costs for reloading the seeder during sowing. Moreover, when dismantling the inter-bunker partition, the capacity of the grain bunker increases to 1280 liters.

For the formation of an ideal seed bed, a design of offset placement of the coulter discs is used, which also protects it from clogging with stones. At the same time, the first disk cuts through a straight sowing line, cuts the harvest residues, and the second loosens the soil and prepares the seed bed.

The set depth of seed sowing is achieved due to the mechanism of pressure springs, which, in addition to adjusting the depth, allow the coulter mechanism to copy the surface of the seeded area. The rolling-adjusting wheelwheel located behind the coulter supports precise control of the depth of seed placement, ensures the contact of the seed material with the soil, which is necessary for optimal moisture inflow through the capillaries, uniform formation of the root system and germination.(//tractor-service.com)

For aggregating the planter with differenttypes of tractors a mounted or trailed version is provided, and the option of longitudinal transportation allows transporting SZM planters on general purpose roads.
