Fertilizer seeders.
Due to the type of towing power used, fertilizer seeders can be divided into horse-drawn and tractor-mounted and mounted. Each seeder consists of a fertilizer box resting on wheels, the sowing unit, sowing amount regulating mechanism and drive system. The drive of the sowing units can be from the road wheels (horse and trailed tractor seed drills) or in seed drills suspended from the tractor power take-off shaft. Depending on the type of sowing unit, fertilizer drills can be divided into: discs, augers and seeders with a paddle-type sowing unit.
