First Claim
Patent Images
1. An apparatus for use with a farm implement, the apparatus comprising:
- a pair of rotatable discs, each disc including;
a generally planar central region having a first side and an opposing second side, the central region defining a plane of the disc; and
a plurality of teeth extending from a periphery of the central region, each tooth having a profile consisting of a concave first edge, a convex second edge, and a substantially linear crown connecting the first edge to the second edge;
wherein the teeth are configured to provide means for minimizing distribution of crop debris removed by the discs from a planting row so that the amount of debris which overlies adjacent planting rows is minimized.

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 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.
