A cutting and threshing blade for a bush hog, wherein the blade has a trailing edge and a leading edge. At least a third of the leading edge of the upper-side of an elongate distal portion of the blade has a knife edge with a knife length that thickens toward the trailing edge. The trailing edge can have an upward air deflector. The bottom-side of the elongate distal portion has a threshing element, which includes a threshing block, which is a steel block having a block length that is comparable to the knife length and projects downward and substantially parallel to the knife edge. The rotating blades pummel growth carriers (i.e.; cob, husk) bearing seeds, grains, and kernels with enough force that they are released. The synergistic rotating knife edge and threshing block transform the bush hogging process from a cutting process to a cutting and threshing process.
