This harvester is the best efficiency of gains and the agronomic requirements is improved in this paper, To design the overall structure and calculate the main parameters, we analysis the harvester on the powertrain process, design and calculate transmission system detailedly, At the same time, the eccentric vibration isolation devices and mining spade are designed for improving the characteristic of the harvester. The cooperation of the ponents is aslo analysised to enhance the quality of the harvesting. This mechinery is overall reasonable layout, highefficiency gains, and suitable for harvesting the potato which grows in a variety of soil conditions.
