Abstract
A blade sharpening system is provided that includes a base, and a rod extending from the base. The blade sharpening system also includes a sharpener slidably coupled to the rod and configured to engage a generally circular blade of an agricultural implement while the generally circular blade is mounted on the agricultural implement. The sharpener is also configured to move along the rod to accommodate lateral variations in a profile of the generally circular blade.
Claims18
A blade sharpening system, comprising:
- a base;
- a rod extending from the base;
- and
- a sharpener slidably coupled to the rod 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 sharpener is configured to move along the rod to accommodate lateral variations in a profile of the generally circular blade;
- comprising a biasing assembly configured to urge the sharpener toward the generally circular blade;
- wherein the biasing assembly comprises:
- a first gear rack coupled to the sharpener;
- a first pinion gear engaged with the first gear rack;
- a second pinion gear coupled to the first pinion gear;
- and
- a second gear rack engaged with the second pinion gear, wherein a weight of the second gear rack urges the sharpener toward the generally circular blade via rotation of the first and second pinion gears.
