摘要:
A scraper assembly for a double disk furrow opener having a hinge bracket bolted rigidly to the cast boot assembly. Scrapers are supported by the hinge bracket and urged against the inside of the blades by a leaf spring. The bolt holds the relative position of the assembly to prevent the scrapers from overhanging the edge of the disk blades, and the leaf spring allows individual scraper action.
