Abstract: As an important food crop, mechanized production technology development for potatoes has consistently drawn significant concern．Due to relatively late start of mechanized potato production technology research and development in China, a significant gap exists between core technologies for key harvesting processes and those in Europe and United States．Structural types and characteristics of potato-soil-vine separation devices in potato harvesters from both domestic and international sources were summarized and analyzed．Future development trends and prospects for potato-soil-vine separation technology in potato harvesting process were proposed, aiming to provide a reference for professional engineering technicians engaged in potato mechanization technology research．
