Siewniki, or sowing machines, are agricultural implements designed to plant seeds at controlled depth and spacing. They are typically mounted on or pulled by tractors and consist of a seed hopper, a metering mechanism that dispenses seeds at a chosen rate, distribution tubes that carry seeds to the soil, and row opener devices that create furrows. A depth-control element, such as a press wheel or depth gauge, helps close the furrow after sowing. Modern models may include pneumatic or electro-mechanical metering, electronic control, and the ability to vary the seeding rate across a field.
Types and configurations vary. Mechanical siewniki use a gear or wheel-driven metering system and are common
