PROBLEM TO BE SOLVED: To provide a rhizome crop harvester capable of easily adjusting an airframe while confirming a state of a crop extracted by an auxiliary worker other than an operator, and capable of efficient harvesting work. SOLUTION: A traveling unit having a traveling device which is located on both sides in the traveling direction of a vehicle body and travels across the ridges and 10 can be rotated up and down, and the stems of rhizome crops on the ridges are sandwiched between the left and right sides in the traveling direction. A bulb portion 20 provided below the rear side of the pull-out transport portion 20 and having a conveyor belt 21 for pulling out to the rear upper diagonal side and transporting to the rear side, and a bulb portion dropped from the rear side of the pull-out transport portion 20. A first operation for operating the traveling unit 10, the pull-out transport unit 20, and the bulb transport unit 40, which are provided close to the bulb transport unit 40 that transports the bulbs on the transport belt 42 diagonally upward and backward. A second operating unit 70 is provided close to the rear side of the bulb transport unit 40, and operates the traveling unit 10, the pull-out transport unit 20, and the bulb transport unit 40.
