Answer Details
The function of the scraper on a disc plough is to remove adhering soil from the disc. As the disc plough cuts through the soil, soil particles stick to the disc due to the pressure and friction. The scraper, which is usually located behind the disc, scrapes the adhering soil off the disc, preventing it from accumulating and reducing the effectiveness of the plough. This helps to maintain the depth and width of the furrow and ensures that the plough functions optimally.
