[PROBLEMS] To eliminate the need for the operation of pulling out the root stock from the ground, thereby eliminating the increase in power and the weight of the components associated with pulling out the root stock, simplifying the root stock removal operation, and improving handling and workability. A possible root stock removal method and root stock removal apparatus are provided. A root drill having a drilling drill extending in the axial direction on the lower side and a crushing blade extending in a direction crossing the axial direction on the upper side is lowered while rotating. The drilling drill 42 drills and bites the root stock 9, and the crushing blade 43 cuts into the root stock 9 following the biting state of the drilling drill 42 to crush the root stock 9. Is prevented by the drum member 3. [Selection] Figure 1【課題】根株を地盤から引き抜く動作を不要とすることにより、根株引き抜きに伴う大動力化、構成部材の大重量化をなくし、根株除去操作を簡素化して取り扱い性及び作業性を向上させることが可能な根株除去工法及び根株除去装置を提供する。【解決手段】軸方向に延びる穿孔ドリル４２を下側に、軸方向と交差する方向に延びる破砕刃４３を上側に備えた根株カッター４を回転させながら下降させる。穿孔ドリル４２が根株９を孔掘りして食い込み、穿孔ドリル４２の食い込み状態に続いて破砕刃４３が根株９に切り込んで根株９を破砕し、根株９の破砕時に根株の破片の周囲への飛散をドラム部材３によって防止する。【選択図】図１
