A cutterhead is disclosed for a motor-driven vegetation cutter and has a rotating housing and a spool journalled therein on which a cutting filament is wound. The spool has a plurality of cams, which coact with at least two spring-loaded coupling members pivotally mounted on the housing for paying out the cutting filament in incremental lengths. Each of the coupling members is pivotally journalled on its own pivot mount on the housing such that it is pivotable in dependence upon centrifugal force. The pivotable coupling members are synchronously displaceable and are coupled to one another for this purpose via an intermediate ring which is supported on the housing so as to be freely rotatable with respect thereto. |
