Protective shield for debroussailleuse.

The invention relates to a protective shield for a brush cutter (1), the cutting head (4) rotatable about an axis of rotation (3), supports a cutting wire (5) which, when the head is rotating, rotates in one direction (10), then turned so as to roughly radial with respect to the axis (3) and determines a cutting circle (6) at least partially covered by the shield ( 2). In the circumferential region of the cutting circle (6), a cutter (7) for cutting to length, provided for the cutting wire (5) is arranged on the shield (2). A cutting edge (8) of the knife (7) is, with reference to the axis (3), offset in height relative to the cutting circle (6) in an axial direction (9). Is provided, at the height of the knife (7), means for the axial deflection of the rotating cutting wire (5) extending from the cutting circle (6).
