The average age of agricultural workers is aging. We focused on under-trellis work done on crops on the shelf with raising their arms. In the upward work, it is necessary to keep the arm with its own weight of approximately 2 to 4 kg. It is considered to be a cause of fatigue of arms and back. Therefore, in this research, we attempted to reduce the fatigue of the upward work by the weight compensation mechanism that balances the elastic force of the spring and their arms weight. It can compensate for their arms weight by the force of the spring in various postures of the arm at the time of work by using lightweight and highly accurate weight compensation mechanism authors developed. In this paper, in order to verify the practicality of TasKi at the agricultural site, we conducted a test survey simulating apple harvest under cooperation of San-nohe cho, Aomori Prefecture. As a result of the questionnaire survey, 80% of subjects showed favorable opinions on assisting method of TasKi.
