Abstract: Unsmoothed surface electro-osmosis method is one of the methods to resolve adhesion problems of the soil touching parts of terrain machinery. The unsmoothed surface electro-osmosis lugs were developed by using this method and through the tests of reducing adhesion and scouring of soil about them. It can be concluded that the lugs have good function of reducing adhesion and scouring of soil, resulting in the increase of trative force and drive efficiency.
