Near-north Ontario, French River | One thing to consider if you have any stones at all is the need to constantly re-adjust the knives on the coulters. When a coulter hits a stone , it it obviously jumps up to clear the stone but when it reneters the soil, the knife is frequently knocked out of adjustment. Its not a real serious issue unless running in heavy residue as well, as when the knife is knocked out of adjustment it opens the gap between the coulter and knife which may or may not lead to residue plugging. |
