Abstract
A grain drill row unit includes a furrow opening device that opens a furrow into which seeds are deposited as the machine advances, and a combination gauge and press wheel rides along the ground behind the furrow opening device to firm the soil around the seed and to control the depth at which the furrow opening device operates. A paddle type scraping wheel is rotatably mounted on a support above the gauge wheel axis, the scraper wheel having edges at the outer ends of the paddles, generally parallel to the axis of the scraper wheel but angled relative to the axis of the gauge wheel, the scraper wheel edges engaging material on the periphery of the gauge wheel and being rotated by contact with said material so that the scraper wheel edges scrape the periphery of the gauge wheel.
