60～70cm。In order to solve the problem that the turning cutter of commonly used sugarcane leaf shattering and returning machine could not pick up the sugarcane leaf from the bottom of furrow, a pick-up device was designed. The inclined rod is connected to the positioning wheel rigidly, and both of them are aligned with the tractor wheel. The bottom end of inclined rod, touching with the soil surface, can pick up the sugarcane leaf from soil surface, lift to a certain height, and promote the feeding height. The power consumption of the machine was saved, and the pick-up rate and shattering rate were improved by 3.4%～4.3% and 9.4%～11.8% respectively. The pick-up device key structural parameters values were determined by theoretical analysis and field tests as follows: the inclined angle 40°～ 60°of inclined rod, and the distance 60～70 cm between the bottom end of inclined rod and the machine cover. 
