King grass is a high-quality perennial forage crop,which is widely planted in southern China.It has the char-acteristics of vertical cluster,and it is difficult to harvest by mechanized flat stubble.In this paper,based on the technical requirements of mechanized harvesting of king grass,a technical scheme of drive system was proposed.Its structure and working principle were introduced,and the drive system was designed and developed.Through theoretical analysis and calculation,the main parameters of the drive system were matched.And the drive system was equipped with the proto-type.The performance test showed that the maximum driving speed of the prototype can reach 9.13 km/h,it can continu-ously change speed in low-speed gear,and the straight deviation rate was 4.115％,which met the operation requirements of mechanized harvesting of king grass.
