SUP 29RM Seed drill cu with double disc coulter. Seed drills offer the optimal solution for sowing several types of seeds on land with different levels of preparation, from well-prepared to those with minimal preparation. The equipment with double disc coulter gives a better precision and a constant depth of the sowing in rows of the seeds of the crop plants. An important advantage of double disc coulters is that they do not collect plant debris, contributing to their shredding.
