The brush cutter cutting head comprises a passage for a cutting wire (300) and a roundness (120) for the support of the wire extending between a wire outlet region from the passage and a head peripheral region. The roundness surface has a hollow profile (120a,120b) so as to guide the cutting wire in the hollow when the wire bends in a direction opposite to the rotation of the head. An Independent claim is included for a brush cutter. |
