PROBLEM TO BE SOLVED: To facilitate stably maintaining preferable sharpness in cutting fibrous roots.SOLUTION: A root vegetable harvesting machine includes: a harvesting part harvesting and transporting root vegetables of a farm field and a cutting blade 30 positioned in a transportation passage for the root vegetables to cut fibrous roots a3 of the root vegetables. A cutting part K is inclined so that one end part in a width direction of the cutting part K of the cutting blade 30 is positioned upstream in a transportation direction for the root vegetables relative to the other end part in the width direction of the cutting part K.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】ひげ根の切断において、良好な切れ味を安定的に持続させ易くする。【解決手段】圃場の根菜を収穫して搬送する収穫部と、根菜の搬送経路に位置して前記根菜のひげ根a3を切断する切断刃30とが備えられ、切断刃30の刃部Kの幅方向における一端部が、刃部Kの幅方向における他端部よりも根菜の搬送方向における上流側に位置するように、刃部Kが傾斜している。【選択図】図3
