A rotating weeder member (16, 23) for a weeder machine (1) is described, comprising a plurality of hook- like elements (17) rigidly supported at one of their extremities by a single connecting ring (18) rotatably mounted to support means (15, 21) of the weeder machine (1), radially equally spaced with respect to the rotation axis (A) of the member (16, 23) to form a rotoidal discontinual open structure for the passage of the lifted soil, having an open internal cavity (190) and a sequence of outward convex portions (172) of said elements (17) adapted to sequentially interact with the soil to be worked. |
