Abstract
A filament cutterhead for a brushcutter is able to be driven in a rotatable manner during operation in a rotational direction about a rotational axis. The filament cutterhead has a base body on which at least one cutting filament is retained and which has a lower face facing the ground during operation. The cutting filament extends from an outer face of the base body through an opening as far as an inner region of the base body which is open toward the lower face of the base body. In order to achieve a low degree of soiling of the filament cutterhead during operation, a shield element is provided in the inner region and the leading portion of the cutting filament in the inner region is arranged in the slipstream of the shield element relative to the rotational direction.
