Angelica gigas, Astragalus membranaceus and Ligusticum chuanxiong have been grown for a long time in Korea as medicinal crops with underground parts. Its harvesting method has been depended entirely on manual labor. Therefore, harvesting involved much work. This study was to determine an effective mechanized harvesting method for underground parts of some medicinal crops by several machines. Labor time was decreased by 61 percent in Angelica gigas and by 70 percent in Astragalus membranaceus by the use of poclain harvester, however, in Ligusticum chuanxiong was decreased 68 percent by multi - root harvester compared with conventional system (manual harvest). The poclain harvester was suitable for harvesting in Angelica gigas and Astragalus membranaceus plots, but multi - root harvester was not satisfactory. Multi - root harvester appeared to be appropriate harvester for Ligusticum chuanxing.
