Design and Testing of a Small Remote-Control Hillside Tractor

Abstract. To address the current lack of hillside agricultural machinery in China, a small remote-control tractor was designed, and its overall performance was tested. The results showed that the tractor exhibited good turning, with a minimum turning radius of 418 mm, which is suitable for use in mountainous regions in a narrow operating environment. The linear travel of the tractor was ideal, with a yawing rate of 0.86%. A parallelogram mechanism and subsoiling shovel were used with a single-furrow reversible plow to effectively solve the partial traction problems; the traction and adhesion performance were good. When the slip rate was 5% to 10%, the driving force from the driving wheel was optimal. The results suggest that this machine is suitable for the special operational requirements of mountainous areas.
