Abstract
A residue coulter apparatus that cleanly severs and clears crop debris from a planting row, causing minimal disturbance to the soil. The residue coulter apparatus comprises a pair of flat discs each having a plurality of back swept shark type teeth extending about their periphery. The teeth include a double beveled cutting edge on the outer edge of the teeth adapted to sever residue from the field. The clearing discs are oriented substantially vertical to the ground. Two clearing discs are used in combination to clear a pathway for planting seed. The clearing discs are angled toward each other so that the leading edges of the clearing discs are pointed in a toe-in orientation. The present design effectively removes crop debris without over discharge and causes minimal soil disturbance.
