Abstract
A filament cutterhead is provided for mounting on the drive shaft of a brushcutter. The filament cutterhead includes a housing with a circumferential wall wherein a first wall opening for a cutting filament is formed. A filament spool arranged in the housing is rotatable relative to the housing. A filament channel with a filament inlet segment is provided in a partition wall of the filament spool. The filament channel extends from the filament inlet segment past the hub to a filament outlet segment which is assigned a second wall opening in the circumferential wall. The filament outlet segment is at an offset (v) with respect to the filament inlet segment in the circumferential direction of the hub. The mouth of the filament inlet segment and the mouth of the filament outlet segment lie within an outside diameter (A) of the partition wall and open into a pass-through space.
