Field test on electro-osmotic lubrication on mole plow is reported in this paper. Analysis on ground resistance of the implement is also discussed. Tests were conducted both in an loam upland field and in a sandy loam paddy field. At paddy field, tests were conducted at plowing depths of 30 to 50cm and operating speeds of 1.20 to 3.49km/h. At upland field, tests were conducted at plowing depths of 31 to 34cm and operating speeds of 0.15 to 1.11km/h. Voltage applied between the cathode (disk coulter and expander) and the anode (chisel and shank) was DC 250V. In paddy field test at a depth of 32cm, 5.6 to 13.2% reduction of draft was observed, and the flow of current was 0.89 to 1.20A. In upland field test at a depth of 30cm, -9.2 to 4.5% reduction of draft was observed, and the flow of current was 0.62 to 0.93A.
