Abstract. The agricultural labors are rapidly decreasing due to the aging of the agricultural population and the feminization. In Korea, radishes account for around 78.1% of the root vegetables in 2014, and the ratio of labor in harvesting and transporting work is about 26.7%. Therefore, it needs to develop the agricultural mechanization technology, especially radish harvester, because radish harvester of pulling type is directly contacted with soil during harvesting. Then, strength analysis of harvesting part is needed. In this study, finite element analysis was carried out using ANSYS Workbench in order to find out the weak point of the harvesting part of the harvester. The 3D model of the harvesting part including driving pulleys, shafts, and V-belts was designed by using CATIA V5 R18. The maximum load of 16.82 Nm measured in the field test was input to the driving shaft. The driving pulleys, shafts, and V-belts were simulated, and analyzed the deformation and equivalent stress. Simulation results revealed the maximum deformation and equivalent stress on the driving shaft. The results showed that the driving shaft of the radish harvester is the weakest point. Thus, the simulation results should be sufficiently considered during the design of the driving part of the harvesting part.
