Bush hog cutting and threshing blade

A cutting and threshing blade for use on a bush hog, wherein said cutting and threshing blade comprises:

• a bar of steel that has a bottom-side (ground side), an upper-side, an overall length, a width, and a thickness, wherein the bar has a medial short portion contiguous with a transitional curvilinear portion that is contiguous with an elongate distal portion;
• said medial short portion having a hole for attaching the blade to a bush hog's rotor forming an attachment that allows pivotal rotation of the blade on the bush hog's rotor;
• said elongate distal portion and the medial short portion are approximately parallel and about coplanar and the transitional curvilinear portion contains curved sections and a straight section;
• said elongate distal portion has a leading edge and a trailing edge and, where at least a third of the leading edge has a protruding knife edge with a knife length that thickens toward the trailing edge;
• a threshing element comprising a threshing block, which is a steel elongate block, on the bottom-side of the elongate distal portion, said threshing block having a block length that is comparable in length to the knife length, wherein said threshing block has a block height sufficient to extend beneath the bottom-side of the elongate distal portion and downward 3 to 7 times the thickness of the bar of steel, wherein an inboard wall of said threshing block is tapered at about 45 degrees and an outboard wall that is about perpendicular to the upper-side of the distal end of the elongate distal portion;
• said threshing block, being below and behind the cutting edge adds weight increasing momentum and surface area, when the cutting and threshing blade impacts a growth carrier that is bearing seeds, grains, and kernels, the threshing block pummels the growth carrier with enough force that the seeds, grains, and kernels are released;
• and
• a synergistic juxta-positioning of the knife edge with the threshing block transforms bush hogging from a cutting process to a cutting and threshing process.

A cutting and threshing blade for use on a bush hog or a mower, wherein said cutting and threshing blade comprises:

• a bar of steel that has a bottom-side (ground side), an upper-side, an overall length, a width, and a thickness, wherein the flat bar has a center portion that is contiguous with a left transitional curvilinear portion contiguous with a left elongate distal portion, and is also contiguous with a right transitional curvilinear portion contiguous with a right elongate distal portion;
• wherein the center portion has at least one mounting element for directly or indirectly attaching the blade to a shaft;
• wherein the left elongate distal portion and the right elongate distal portion are approximately parallel and coplanar and symmetrically offset from with the center portion, wherein an amount of offset is determined by a shape of the left transitional curvilinear portion and the right transitional curvilinear portion;
• wherein the left elongate distal portion and the right elongate distal portion respectfully have a left leading edge, a left trailing edge, a right leading edge, and a right trailing edge, where at least a third of the left leading edge has a left knife edge with a left knife length that thickens toward the left trailing edge, and where at least a third of the right leading edge has a right knife edge with a right knife length that thickens toward the right trailing edge;
• a threshing element comprising a left threshing block and a right threshing block, which are both steel elongate blocks of about the same weight and dimensions, and located, respectfully, on the bottom-side of the left elongate distal portion and the right elongate distal portion, wherein the left threshing block and the right threshing block each have a block length that is comparable in length to the left knife length and right knife length, wherein each of the respective left and right threshing blocks has a block height sufficient to extend beneath the bottom-side of the left and right elongate distal portions downward 3 to 7 times the thickness of the bar of steel, wherein inboard walls of both the left and right threshing blocks are tapered at about 45 degrees and outboard walls are about perpendicular to the upper-side of the respective left and right distal ends of the respective left and right elongate distal portions;
• said respective left and right threshing blocks, being below and behind the respective left and right cutting edges, add weight increasing momentum and surface area, when the cutting and threshing blade impacts a growth carrier that is bearing seeds, grains, and kernels, the threshing blocks pummel the growth carrier with enough force that the seeds, grains, and kernels are released;
• and
• a synergistic juxta-positioning of the respective left and right knife edges with the respective left and right threshing blocks transforms bush hogging and mowing from a cutting process to a cutting and threshing process.
