ABSTRACT:
A coulter is provided to create furrows in a field, while at the same time reducing the amount of soil and debris which accumulates on the coulter disc. The coulter has a disc for creating furrows, with a floating scraper blade on the inner side to keep the inner side of the disc free of debris. The scraper blade also assists in maintaining the furrow once it has been opened by the disc. A tine extends across the outer side of the disc in a configuration that prevent soil from adhering to the outer side of the disc, and in trash covered fields, trash will wrap around the tine to act as an organic wear pad between the disc and the tine.
