Lotus are usually cultivated in the slime soil of paddy field in Korea. Cultivation area of lotus roots as an alternative of a rice plant has been increased greatly during several years due to the decrease of rice price. Lotus roots are grown horizontally in the depth of about 30 cm inside the slim soil. Lotus roots are used as the health food. The harvesting of lotus roots requires the great labor and is usually done by manual labor as digging with hoe. The objective of this study was to develope the lotus root harvester for providing the convenience on harvesting of lotus roots by soil breaking with injecting air of high pressure into the soil. The constructed harvester of lotus roots was composed of the main body with two air cylinders, two sliding plates, and an instrument for air ejection including nozzle, high pressure container, handle, and lever.
