A device for mowing, comprising a rotatable shaft () and a plurality of supporting structures () arranged along the shaft (), each of which structures supports a plurality of circumferentially arranged and radially extending blades (), each of which blades exhibits a radially extending blade edge () which extends to the free blade end () and which, on rotation of the aforementioned shaft (), are arranged for mowing. Each blade edge () is angled in relation to a blade plane extending perpendicularly in relation to the aforementioned shaft () at an angle (a) of less than 45°, and the free blade ends () of the blades () in each of the aforementioned supporting structures () are distributed between at least three blade positions (KP) that are mutually separated in the axial direction. 1. Device for mowing , comprising:a rotatable shaft anda plurality of supporting structures arranged along the shaft, each of which supports a plurality of circumferentially distributed and radially extending blades, each of which exhibits a radially extending blade edge which extends to a free blade end and which, on rotation of the aforementioned shaft, are arranged for mowing,each blade edge being angled in relation to a blade plane extending perpendicularly to the aforementioned shaft at an angle which is less than 45°, andthe free blade ends of the blades on each of the aforementioned supporting structures being distributed between at least three blade positions mutually separated in the axial direction.2. Device for mowing according to claim 1 , in which each blade edge extends at an acute angle to an edge plane claim 1 , which is defined by the extension of an associated blade in the radial direction and the extension of the shaft in the axial direction.3. Device for mowing according to claim 1 , in which the supporting structures are arranged in supporting structure positions claim 1 , each pair of adjacent supporting structures exhibiting blade positions situated in the axial ...
