ABSTRACT:
A scraper device for clearing earth and other materials accumulated on ground working elements, such as discs of a plough. The scraper device is suspended from the frame and is free to swing toward the ground working element. When a layer of earth or other material has accumulated on the element, a blade on the device will engage the layer and bite into it, thereby removing the layer as rotation of the element continues. After the layer has been removed, the blade swings away from the element.
