Design and control system development of 2CM-4EF potato planter

Design scheme of 2CM-4EF potato planter was introduced, and key components such as mainframe, sowing device, fertilization device, and soil covering components were analyzed．Hydraulic control system was simulated and analyzed by using AMESim software and combining it with Simulink software．Results showed that overall machine and hydraulic control system operating effect could meet user's needs, and provide reference for enterprises engaged in potato planter research and production．
