This invention relates to a cutting device, being able to be applied on an appliance and intended to turn away for an obstacle from a normal position, the cutting device having a longitudinal direction which is essentially perpendicular to the intended motion direction of the appliance and the cutting device being intended to cooperate with a spring means, by which the cutting device is intended to return to its normal position after having passed the obstacle. According to the invention the cutting device (1) is intended to be pivotally fastened on a bar (14), the longitudinal direction of which is essentially parallel with the longitudinal direction of the cutting device, and which connects the fore ends of in normal position two essentially horizontal arms (15, 16), positioned at a distance from each other, the arms (15, 16) being pivotal about an essentially horizontal axis (X), the direction of which is essentially parallel with the longitudinal direction of the bar (14). The cutting device (1) is divided into a plurality of sections (3, 4, 5), each section being revolvable in both a clockwise and a counterclockwise direction about an essentially horizontal axis (Z), the direction of which is essentially perpendicular to the longitudinal direction of the cutting device (1). |
