Abstract: Aiming at the difficult problem of agricultural machinery operations under special environmental conditions for fruit planting in hilly and mountainous areas,based on the design ideas of multi-function,light weight and good adaptability,a multi-functional light chassis was developed,which can be equipped with transportation,weeding,rotary tillage,and spraying.A variety of agricultural machinery and tools can not only solve the problem of mechanized operations in hills and mountains to a certain extent,but also have important significance for improving the level of agricultural mechanization in hills and mountains and promoting the development of agriculture and society in hills and mountains.
