Coulters

Coulters play an important role in planting and tilling. Deployed ahead of drill openers, effective coulters can greatly improve seed to soil contact by cutting up trash and debris and providing the right amount of gentle tilling. Deployed on chisel plows or with rippers, quality coulters greatly improve performance and efficiency by eliminating drag caused by shallow roots and turf. McKay uses only the toughest grades of steel, effective hardening techniques, and strict quality-control to produce coulters that stay true and deliver consistent results; consistent results lead to better yields. Our coulter line is wide and we can produce custom styles as well. We’ll make sure you find a tool perfectly matched to the job.
