Описание: The Weaving GD Drill is particularly effective for low disturbance drilling and cover crop drilling, because it consists of two discs of slightly different sizes, set at a 25-degree angle off the vertical. The large discs are on the bottom and it cuts through the soil, while the top disc gently lifts the soil. A single press wheel then firms the lifted flap of soil back into place. Traditional double disc openers are vertical and are pulled in the direction the tractor is travelling in, creating two hard walls for the poor seed to try to strike through. By contrast the GD openers slices the soil without compression on both sides and the smaller top disc creates tilth that enhances germination. They are also less prone to hair-pinning.
