PROBLEM TO BE SOLVED: To provide a rhizome crop harvester capable of reducing the width of an airframe when not in use. SOLUTION: From a traveling unit 10 that runs across ridges, a pull-out transport unit 20 that sandwiches a stem of a rhizome crop that can rotate up and down, pulls it out diagonally backward and upward, and conveys it to the rear side, and a pull-out transport unit 20. A bulb transporting portion 40 that transports the dropped bulb portion to the rear upper diagonal side, and a bulb transporting portion 40 that is provided close to the side of the pull-out transporting portion 20 and projecting laterally from the traveling portion 10, and the traveling portion 10 and the pull-out transporting portion 20 and The operation unit 50 for operating the bulb transport unit 40, the operation unit 50 is operated by the operation table 51 for the worker B to get in, and the worker B to operate the traveling unit, the pull-out transport unit 20, and the bulb transport unit 40. The operation unit 50 is provided with an operation panel 55 for the purpose, and the operation unit 50 can be changed between an unused state in which the operation unit 50 is folded and stored on the pull-out transfer unit 20 side and a use state in which the operation unit 50 is expanded laterally from the pull-out transfer unit.
