序言目前,国外的山地用拖拉机已经由研制阶段开始在生产中应用了。山地用拖拉机克服了普通型拖拉机沿等高线作业带来的弊病,具有操纵性、作业性能、牵引性能好,横向稳定性高,驾驶安全等优点。因此,世界各国都在研究以等高线方向稳定作业为目标的山地用拖拉机。可是,在急陡坡地用的拖拉机还没有实用的例子。 Preamble Currently, foreign mountain tractors have been used in the production stage from the development stage. Tractor with a mountain overcame the shortcomings of ordinary tractors along the contour operation, with maneuverability, operating performance, traction performance, high lateral stability, driving safety and so on. Therefore, all countries in the world are studying mountainous tractors with the goal of stable operation in the contour line. However, there are no practical examples of tractors on steep slopes.
