A rotatable head for a rotary cutter comprises a circular base plate 7 which is rotatable about its axis. Arranged about the upper surface of the base plate are retainers having holes 7 or channels passing therethrough in a direction radial to the axis of rotation. Culling elements 11 having an elongate filament 12 and an enlarged end portion (13) (Figure 2) are mounted in respective ones of the retainers by insertion of the filament through the hole or channel, the elements being retained during rotation of the head by the abutment of the enlarged end portion (13) against the radially inner side of the hole or channel. The holes or channels are so formed that during rotation the elements can pivot with respect to the mounting portions. <IMAGE> |
