Abstract
There are many levee slopes surrounding paddy fields in hilly and mountainous region in Japan. Large levee slopes with their slope length over 3 meters increase after land consolidation. These large levee slopes make more difficult and harder to be maintained. Therefore, we planned and manufactured a trial suspended slope mower to reduce the weeding load, and investigated its performance. The mower consists of two units, one is parent unit suspending and drawing child unit via a rope reeled by a winch on it, and the other is child unit mowing weeds in the slope. Its working efficiency was from 3 to 6 ares per an hour, while increase ratio of heart rate on mowing was from 20 to 30 percents.
