In Rakkyo (Allium chinense) cultivation, the semiautomatic type planting machine, the harvesting machine and the semiautomatic type cutting machine to cut off both roots and stalks of Rakkyo bulbs were developed. The total working hours was reduced to a half of conventional cultivation by adopting developed mechanical cultivation system in the two years Rakkyo cultivation. As for the planting machine, the planting hours per 10a were shortened to five hours and it was about 60% of hand planting. In harvesting, the developed machine shortened harvesting hours per 10a by two hours and it was only 8% of hand harvesting. And using developed cutting machine, even workers who were not accustomed to the work in cutting off the roots and stalks of Rakkyo, the processed amount and the quality of processed bulbs were almost the same as the experienced operator, Kiriko did.
