Abstract

Implement for snow-ploughing or the like designed to be advanced by a vehicle during operation and consisting of a plough blade 1 with a lower working edge 3 which can be angled in the direction of travel and can, at its front end edge 6, have an extra blade 2 connected, which is fastened in a bearing on a spindle 8 which is fixed in the plough blade 1 essentially at right angles to its main direction. The blade 2 consists of on the one hand a part located at a distance from the spindle with an outer end edge 21 and a lower working edge 20 which, in the folded down position of the extra blade, is designed to be situated in line with the working edge 3 of the plough blade 1 in such a manner that it, like the plough blade 1, bears against the surface, and an upper edge 23 essentially parallel to the working edge, and on the other hand an inner part 22 close to the spindle with a working edge which is a continuation of the working edge 20 of the outer part, and an upper edge 24 which is arranged in such a manner that a triangular area is formed when the extra blade is folded down into its bottom working position, in which its working edge constitutes an extension of the working edge 3 of the plough blade, running essentially parallel to the main direction of the plough blade, and the extra blade is then located with its outer part outside the end edge 6 of the plough blade while its inner part is situated in front of the plough blade and overlaps the latter partly. In addition, there is a lifting mechanism 16, 18 (Fig. 3) for pivoting the extra blade steplessly from the lower working position up to the higher. <IMAGE>
