Many methods, such as materials modification, surface shape design, vibration, lubrication, electricosmosis and magization, were adopted to reduce the soil adhesion force between soil and the surface of soilengaging ponents. Some research conducted found that polymeric materials and enamel coating had the ability to reduce soil adhesion [6, 12, 13, 14 and 17], but the polymeric materials had poor abrasion resistance against soil. The surface shapes of the soilengaging ponents played an important role in reducing soil adhesion and friction. A kind of ettype passageholes mouldboard was made to reduce the plowing resistance [19]. Ultrasonic vibration and mechanical vibration experiments were conducted, indicating the reduction of soil adhesion and soil friction resistance due to vibration [16 and 18]. Araya and Kawanishi, Schafer and others reported that the airflow, water and polymerwater solution injected in between soil and the surface of soilengaging ponents had a lubrication action and decreased the draft forces of soilengaging equipment [1 and 15]. The electroosmosis method was adopted to reduce soil adhesion and sliding resistance, but a long contacting time for electroosmosis required a limited application of the electricosmosis method [2 and 3]. Han and Zhang et al, studied the effect of the magic field on the plowing resistance of plows. They reported that the plowshare with attached permanent mags on the back had lower plowing resistance and fuel oil consumption of the tractors used for dragging plows than that of the plow without magizing [4 and 5]. The problem of soil adhesion has been solved in some soilburrowing animals such as dung beetle, ant, and pangolin. Some research has shown that some parts of their body surfaces were a kind of geometrical nonsmooth structure. The nonsmooth structure was one of reasons why soilburrowing animals do not stick soil. Fig. 1 illustrates the nonsmooth morphology of the head of dung beetle. Based on the research of the principles of the nonsmooth surfaces of soilburrowing animals in antiadhesion against soil [7], bionic nonsmooth methods were developed to reduce soil adhesion. Some bionic bulldozing plates were designed and made to test the mechanism of nonsmooth surfaces on the reduction of soil adhesion and resistance [8, 9, 10 and 11]. Several bionic bulldozer blades with varied nonsmooth surface characteristics were designed and tested in o
