Abstract
The present invention is an improvement for a coulter blade for a harvester header attachment designed to slice crop residue and till soil as a harvester is harvesting a field of crops. As a harvester moves through a field of crops, the harvester header attachment's coulter blade spins on a bearing and cuts into the crop's stalks, leaves, and root balls, tilling the standing crop residue. The present invention adds a series of fins to the coulter blade, either directly or on an attachment to the coulter blade, such that the footprint of the blade is larger, allowing it to perform those functions even if not lined up perfectly with a crop row.
Claims4
A coulter blade with a series of coulter blade fins attached directly and perpendicularly to the surface of said coulter blade and arranged radially around the center of said coulter blade, said coulter blade fins being of a length extending out from said coulter blade that widens the footprint of row coverage of said coulter blade.
A fin attachment for a coulter blade comprising:
- a. A disc-shaped fin attachment base for attaching flush to a side of said coulter blade;
- b. A fin attachment assembly hole in the center of said fin attachment base to accommodate an assembly attaching said coulter blade to a tillage assembly;
- c. At least four fin attachment bolt holes around said fin attachment assembly hole for attaching said fin attachment to said coulter blade with bolts;
- and
- d. Extending from the outer edge of said fin attachment base to the area of the fin attachment base just before said fin attachment bolt holes, a series of fin attachment fins arranged radially around the center of said fin attachment base and perpendicular to said fin attachment base, said fin attachment fins being of a length extending out from said fin attachment base that when said fin attachment base is attached to said coulter blade the footprint of row coverage of said coulter blade is widened.
A system for expanding coverage area for a coulter blade such that a row crop may be knocked over, sliced, and pulverized into the soil after harvesting even if alignment of a crop row with said coulter blade is not perfect, the system comprising a series of coulter blade fins attached directly and perpendicularly to said coulter blade, radially around the center of said coulter blade, said coulter blade fins being of a size that widens the footprint of the area of row crop residue that can be knocked over, sliced, and pulverized by said coulter blade while said coulter blade embeds some of said residue into the soil.
A system for expanding coverage area for a coulter blade such that a row crop may be knocked over, sliced, and pulverized into the soil after harvesting even if alignment of a crop row with said coulter blade is not perfect, the system comprising:
- a coulter blade;
- a fin attachment comprising a disc-shaped fin attachment base attached flush to said coulter blade, and a series of fin attachment fins perpendicular to said fin attachment base and said coulter blade, arranged radially around the center of said fin attachment base, said fin attachment fins being of a length extending out from said fin attachment base such that when said fin attachment base is attached to said coulter blade the footprint of the area of row crop residue to be knocked over, sliced, and pulverized by said coulter blade while said coulter blade embeds some of said residue into the soil is widened.
