A flail head for a vegetation cutter having face-to-face cup shaped central body portions separated by a predetermined distance Symmetrically spaced pivot posts extend between the face-to-face central body portions. A fail blade is pivotably attached to each pivot post. In one embodiment of the flail head, the face-to-face body portions are identical and the pivot posts are formed by mating semi-cylindrical posts formed integrally with each of the central body portions. The flail blades and body portions are made from different plastic materials to prevent the fusion or welding of the flail blades to the posts.
