The radishes harvested from the farm contain ones that are short-length or with a forked root. They are called as irregular radishes. The irregular radishes loaded into containers must be eliminated in the radish sizing place after harvest. The radish sizing costs momey and loses time. Therefore we have developed the device eliminating irregular radishes before they would be loaded into the container on the harvester. This eliminating device utilizes photoelectronic sensors and distance measuring sensors. Those sensors detect irregular radishes and the radishes are eliminated in the field before loaded into the container by this device.
