A disc coulter, specifically a disk coulter (10) of an agricultural machine (11) for dispersing seed and/or fertiliser in solid or liquid form, comprising a seeding and/or dosing means mounted between a pair of discs (1, 2) on whose the inner side (4) is abutting a scraping means (3) which is a flat scraper segment (12), which is in resilient pressure to the surface of the discs (1, 2) arranged on at least one flexible plane (5), and the flat scraper segment (12) has its greatest face surface (13) arranged to be touching the surface of the discs (1, 2), so that it is tightly held against the discs (1, 2) and at the same time its shape is adapted to the shape of the surface of the discs (1, 2). |
