Even field emergence
The mulch sowing coulter (weighing 120 kg on its own) can be pressed down further by a spring with a maximum force equivalent to 200 kg. Via a hydraulic cylinder coulter pressures of up to 400 kg is possible. This ensures smooth running and even field emergence under the hardest of conditions. The complete mulch seeding coulter is securely guided by two large carrying rollers. Soil opening is performed by a double disc unit, including a furrow former. Once the seed has been embedded in the soil by the catcher roller, the V-pressure rollers follow to close up the furrow again.
