Coulters are mounted in front of the shank assembly of the deep ripper plough to help with cutting and slicing through tough soil, sod or plant residues before they are overturned by the shank. By cutting into the soil, coulters help to reduce soil resistance, making it easier for the shank to turn the soil over. The cleaner furrow created helps reduce soil disturbance, improves seedbed preparation, and can enhance overall deep ripping performance.
