Abstract
A cutter head for a brush cutter has a base body with top base body part and bottom base body part. A screw element is arranged at the bottom base body part for attachment to an output shaft of the brush cutter. A receptacle for fastening a cutting tool is provided between top and bottom base body parts. The base body is rotatably driven in operation of the brush cutter about an axis of rotation of the base body. The top and bottom base body parts are held together by a detachable snap-on connection. The snap-on connection is positioned at a distance, measured in a radial direction, from the axis of rotation of the base body. The distance amounts to at most 40% of the cutter head diameter. For releasing the snap-on connection, the top and bottom base body parts are pulled apart from each other by a pulling force.
