The purpose of this study was to prevent soil adhesion on the rotary tiller cover. Vibration frequency of 25Hz, 30Hz and 35Hz was applied to the rotary tiller cover for a test soil condition. Distribution and weight of soil stuck on the rotary tiller cover were measured. As a result, it was found that for any test condition, the vibration frequency of 25Hz, 30Hz and 35Hz showed a remarkable effect on preventing soil adhesion to the cover, especially the vibration frequency of 30Hz was the most conspicuous.
