Abstract
An apparatus that cleanly severs and clears crop debris from a planting row or closes a furrow while causing minimal disturbance to the soil. The residue coulter apparatus comprises a pair of flat discs each having a plurality of back swept teeth extending about their periphery. The teeth include a beveled cutting edge on the outer edge of the teeth adapted to sever residue from the field or close a furrow. The discs are oriented substantially vertical to the ground. Two discs are used in combination to clear a pathway for planting seed or for closing a furrow.
