BLADE SHARPENING SYSTEM FOR AGRICULTURAL IMPLEMENTS

摘要

A blade sharpening system (38) is provided that includes a base (40), and a pivoting member (42) rotatably coupled to the base (40) by a shaft (44). The blade sharpening system (38) also includes a sharpener (46) coupled to the pivoting member (42) and configured to engage a generally circular blade (22) of an agricultural implement (10) while the generally circular blade (22) is mounted on the agricultural implement (10). The pivoting member (42) is configured to enable movement of the sharpener (46) to accommodate lateral variations in a profile of the generally circular blade (22). The base (40) has a first plurality of recesses (92, 100, 104, 108, 116, 120, 124) configured to receive the shaft (44) and the pivoting member (42) having a second plurality of recesses (94, 102, 106, 110, 118, 122, 126) configured to receive the shaft (44), wherein the shaft (44) is selectively securable to each of the first plurality of recesses (92, 100, 104, 108, 116, 120, 124), and to each of the second plurality of recesses (94, 102, 106, 110, 118, 122, 126) to adjust the weight urging the sharpener (46) towards the blade and with it to adjust a contact force between the sharpener (46) and the generally circular blade (22).
