In Japan about 400 farmers are killed while farming. Especially due to aging population of farmers accidents caused by senior farmers are increasing. Our institution Bio-oriented Technology Research Advancement Institution (BRAIN) has conducting safety tests on agricultural machinery. Though the tests are based on adult physical performances and not seniors. So we have conducted a survey on senior farmers and female farmers, who are physically weak, to determine if the standards of the safety test can cover the physically weak. The survey focused on popular agricultural machinery as walking tractors and normal tractors. We measured walking speed by walking with a wagon which simulates a walking tractor. And measured handling force and dimension of drivers seat of a normal tractor.
