Abstract
A blade sharpening system is provided that includes a base, and a pivoting member rotatably coupled to the base by a shaft. The blade sharpening system also includes a sharpener coupled to the pivoting member and configured to engage a generally circular blade of an agricultural implement while the generally circular blade is mounted on the agricultural implement. The pivoting member is configured to enable movement of the sharpener to accommodate lateral variations in a profile of the generally circular blade, and the shaft is movable relative to the pivoting member to adjust a contact force between the sharpener and the generally circular blade.
Claims19
A blade sharpening system, comprising:
- a base;
- a pivoting member rotatably coupled to the base by a shaft;
- and
- a sharpener coupled to the pivoting member and configured to engage a generally circular blade of an agricultural implement while the generally circular blade is mounted on the agricultural implement, wherein the pivoting member is configured to enable movement of the sharpener to accommodate lateral variations in a profile of the generally circular blade, and the shaft is movable relative to the pivoting member to adjust a contact force between the sharpener and the generally circular blade;
- wherein the base comprises a first substantially flat plate, the pivoting member comprises a second substantially flat plate, and the shaft is configured to facilitate rotation of the second substantially flat plate relative to the first substantially flat plate about an axis substantially perpendicular to the first and second substantially flat plates.
A blade sharpening system, comprising:
- a shaft;
- a base having a first plurality of recesses configured to receive the shaft;
- a pivoting member having a second plurality of recesses configured to receive the shaft, wherein the shaft is selectively securable to each of the first plurality of recesses, and to each of the second plurality of recesses to facilitate movement of the shaft relative to the pivoting member;
- and
- a sharpener coupled to the pivoting member and configured to engage a generally circular blade of an agricultural implement while the generally circular blade is mounted on the agricultural implement, wherein the pivoting member is configured to enable movement of the sharpener to accommodate lateral variations in a profile of the generally circular blade, and movement of the shaft relative to the pivoting member facilitates adjustment of a contact force between the sharpener and the generally circular blade.
A blade sharpening system, comprising:
- a first substantially flat plate;
- a second substantially flat plate rotatably coupled to the first substantially flat plate by a shaft, wherein the shaft is configured to facilitate rotation of the second substantially flat plate relative to the first substantially flat plate about an axis substantially perpendicular to the first and second substantially flat plates;
- and
- a sharpener coupled to the second substantially flat plate and configured to engage a generally circular blade of an agricultural implement while the generally circular blade is mounted on the agricultural implement, wherein the second substantially flat plate is configured to enable movement of the sharpener to accommodate lateral variations in a profile of the generally circular blade, and the shaft is movable relative to the second substantially flat plate to adjust a contact force between the sharpener and the generally circular blade.
