To address issues of high labor intensity, few applicable machines and poor working conditionsin tea plant management in hilly and mountainous areas, a self-propelled lightweight cantilever tea pruning machine was designed. Based on the agronomic requirements for tea garden management, the overall structure and working principle of the machine were analyzed. An innovative “folding + rotation” arm structure was designed and dynamic simulation analysis was carried out. The key components of the walking device were theoretically analyzed and selected. After creating the prototype, field slope climbing performance test and tea plant pruning test were carried out. The results show that the maximum climbing ability of the pruning machine was 25°, the working performance of the pruning machine was stable, the missed detection rate was 0.55%, the tear rate of tea plants after pruning was 1.36%, and all performance indicators met the requirements of DG/T 110—2024. This study provided a new solution for tea plant pruning in hilly and mountainous areas.
