Abstract
A disc cutter for an agricultural implement includes: a disc body configured to rotate in a rotation direction; a knife mount carried by the disc body and including a body mounting feature; and a knife coupled to the knife mount. The knife includes: a pair of cutting sections each having a knife mounting feature disposed on or in a knife surface between a pair of edges of the cutting sections and configured to couple with the body mounting feature, each of the edges defining a cutting angle with respect to the knife surface such that the edges extend in parallel.

A disc cutter for an agricultural implement, comprising:
- a disc body configured to rotate in a rotation direction;
- a knife mount carried by the disc body and comprising a body mounting feature;
- and
- a knife coupled to the knife mount, the knife comprising:
- a first cutting section comprising a first knife mounting feature disposed on or in a first knife surface between a pair of first edges of the first cutting section and configured to couple with the body mounting feature, each of the first edges defining a first cutting angle with respect to the first knife surface such that the first edges extend in parallel;
- a second cutting section comprising a second knife mounting feature disposed on or in a second knife surface between a pair of second edges of the second cutting section and configured to couple with the body mounting feature, each of the second edges defining a second cutting angle with respect to the second knife surface such that the second edges extend in parallel;
- and
- an offset between the first knife surface and the second knife surface such that the first knife surface and the second knife surface are neither co-planar nor parallel, wherein the offset is positioned against the disc body,
- wherein the first cutting angle and the second cutting angle are the same.
