This coulter is a system designed for sowing cereals in pre-prepared soil, offering a balanced combination of penetration capacity, good furrow formation and adaptability to the terrain. This type of coulter represents an evolution of the tine system, incorporating a suffolk coulter that guides the seed in a more controlled manner to the bottom of the furrow.

The system operates via an opening suffolk coulter that penetrates the soil to create a defined seedbed channel. As the seed drill moves forward, the suffolk coulter displaces the soil laterally and deposits the seed inside the furrow via the drop tube.

Subsequently, the natural flow of soil covers the seed, ensuring its protection and promoting contact with the soil.

One of the main features of the suffolk coulter arm is its good penetration capacity and stability in the ground, which allows for a consistent seeding depth when the soil has been properly prepared. Furthermore, its simple design facilitates continuous operation in the field, with wear-resistant components and low maintenance requirements.

From an agronomic perspective, this system works particularly well in conventional sowing, where the soil has been previously tilled and presents a uniform surface. Under these conditions, the suffolk coulter manages to open a clean furrow and deposit the seed with precision, promoting uniform crop establishment.
