The purpose of this study was to explore a mechanism to prevent soil adhesion to machines using sine wave vibration applied to a test material. An experimental apparatus was constructed using mild steel plate as a model simulating a soil interacting tool. Silt loam soil with six levels of moisture content was used in the experiment. It was sprayed on the plate at several spraying angles, with and without plate vibration. The plate's center, vibrated at a right angle at frequencies between 60 and 100 Hz, showed greater acceleration and a significant effect on preventing soil adhesion when test soil with 38.7 % moisture content was sprayed on it. On the other hand, even without plate vibration, the soil sprayed at smaller spraying angles did not stick to the plate. From this study, it can be concluded that soil adhesion to the plate was closely related to vibration acceleration and spraying angle. Therefore, the effective way to prevent soil adhesion to machines is to vibrate the parts of the machine that come in contact with soil.
