PROBLEM TO BE SOLVED: To provide a weed-pulling machine which can pull out whole weed including roots. SOLUTION: The weed-pulling machine 1 pulls out weeds 71 growing on the ground with moving forward and is equipped with a first roller 4 revolving forward around a rotary shaft 41 horizontally installed perpendicular to the moving direction as a center, and a second roller 5 installed in the rear of the first roller 4, having two or more protrusions 45 extendingly installed on the peripheral surface in shaft direction and revolving backward. The second roller 5 is installed to a position with a space for nipping and holding the weeds 71 with the tip portion of the protrusion 45a, which locates in the nearest position to the peripheral surface of the first roller 4, and the peripheral surface of the first roller 4. The two or more protrusions 45 are arranged in positions where other protrusion 45c locating in the backward of rotary direction from one protrusion 45b shaves the ground locating between the first roller 4 and the second roller 5, when the one protrusion 45b locates in the nearest position to the peripheral surface of the first roller 4.
