Abstract
A protective shield for a trimmer having a cutting head that is rotatable about an axis of rotation and supports a cutting thread that rotates about an axis of rotation with the cutting head and determines a cutting circle, covers at least partially the cutting circle. The protective cover has a base member and a cutting-to-length blade arranged on the base member so as to be positioned circumferentially relative to a cutting circle of the rotating cutting thread. The cutting-to-length blade has a cutting edge that, relative to the axis of rotation of the rotating cutting thread, is arranged in an axially displaced position displaced in an axial direction relative to the cutting circle. A device for axially deflecting the rotating cutting thread out of the cutting circle to the cutting edge is provided.
