  • Wheel track rut filler and compactor
    Publication number: 20050115119
    Abstract: A farm implement for replacing displaced earth into a wheel track rut includes a pair of blades and a rotatable auger carried by a frame which is moved over and along a rut. The blades scrape displaced earth laterally toward and into the rut, and the auger discharges the scraped earth to the rear of the frame. A weighted wheel pulled behind the frame compacts the discharged earth and stabilizes the frame against unwanted transverse movement.
