At present, there are some problems in agricultural mechanization in hilly area, including disadvantageous infrastructure, inadequate attention, insufficient supplement, immature policies and so on. To deal with these problems, government departments, authoritative units, agricultural machine cooperative organizations, scientific research institutions and agricultural machine companies should work together and adopt a series of practical approaches, including upgrading infrastructure, strengthening technical innovation, improving organization system, optimizing industry structure and so on. Different local conditions should be taken into account and the above countermeasures should be applied to realize a rapid, sustainable and healthy development of agricultural mechanization in hilly area
