Abstract. The self-propelled mower was designed to harvest the grass planted in mounted and hills, the copying device is the most critical mechanism of the mower, in order to improve the quality of the harvest, the reasonable design is needed. The copying device of self-propelled mower comprises a sliding palm, four bar mechanism, a lifting hydraulic cylinder and two springs, among them the springs are the most important part. According to the actual situation when mowers work, analyzed the strength and stiffness of the spring on the copying device, designed the spring diameter is 40 mm, the wire diameter is 10 mm and the spring circle is 12. The paper simulated the work condition of the spring by using ADAMS software, the results showed that the spring can meet the requirement of the design.
