中山間地向け水稲作に代表される条件不利地における作業の機械化・軽労化を図ることを目的として， 耕うんから栽培管理までの幅広い作業で多目的に使用できる乗用の小型作業車両とその作業機を開発した。開発機を現地試験に供して性能評価を行った結果，慣行作業体系と同程度の作業性能が得られ，かつ労働 強度の低下による省力化が図られることを確認した。We developed a riding-type small working vehicle and its implements which farmers could use for multi-purpose work from tillage to cultivation management works. Its aim is to save farming labor in disadvantageous areas for agricultural production such as rice fields in hilly and mountainous areas.The developed vehicle has two features; firstly, stability in travelling on steps and resistance to rollover, and secondly availability to attach commercially available machines. For stability, it can vertically move a rear axle and slant the body back and forth, and for resistance to rollover, its center of gravity is lower than conventional rice transplanters. The level exceeds the standard of the safety test on the agricultural machine by approximately ten degrees, with which safe travelling on the sloping way commonly found in hilly and mountainous areas is made possible. With utilizing various kinds of implements existing in the market, it can meet various demands for labor saving of farmers.The result of the field performance test using the developed machine with the new work system showed the same level of work performance as a conventional work system, and that labor saving is made possible through reduction of labor intensity.
