Abstract
The invention relates to a cutter bar 4 for a lawn mower. The cutter bar 4 has two arms 6, 6A, on the front edges 8 of which cutting edges 9 are provided. Starting from the cutting edges 9 there are, adjoining a flat region, wings 7 which are bent upwards. Arranged centrally is a location hole 19, which lies in the centre of an S- shaped reinforcing bead 14. Provided between the front edge 8 and the cutting edge 9 and the rear edge 18 of the wing 7 is a ridge 12 which runs in a curve shape in the plan view of the upper side 11 of the cutter bar and rises from the surface 11. The ridge 12 starts from an end 13 near to the cutting edge 9 and the axis of rotation X-X and becomes increasingly distant from the cutting edge 9 as the radial distance R from the axis of rotation X-X increases and preferably ends at the rear edge 18 of the wing (7). Improved mowing performance in the case of wet grass and a higher degree of filling of a connected collecting device is thereby obtained. <IMAGE>
