Abstract: Southwestern region locates in hilly and mountainous areas, with complex geographical environment, low level of mechanization of potato production, and a large proportion of planting area and output．To lift level of potato production machinery, co-ordinate agricultural machinery in southwest region of China, current situation of potato production mechanization in hilly and mountainous regions of Southwestern China was summarized from aspects of potato varieties, production status, and domestic and foreign production equipment．From planting operation, production mode, production technology, it was analyzed that potato production machinery in the southwest region should have key technologies such as miniaturization, low power consumption, digging and drag reduction, and low harvesting damage．Countermeasures and suggestions were put forward to solve problems of potato mechanized production in hilly and mountainous regions of Southwest China．
