摘要
The invention relates to a device for drawing seed furrows in grassland for the purpose of grassland renewal without ploughing-up. The device is provided with a frame (3) which can be suspended on a tractor and to which haulable slip runners (9) are fastened by means of a spar. The slip runners (9) carry knife-like slitting coulters, the slitting cutting edges (18) of which are designed to slit increasingly deeply into the ground towards the free end of the slip runners (9). There is provided a furrow breaker in the manner of a spike, which, running at a distance behind each of the slitting coulters (17), penetrates into the ground (13) at least as deeply as the deepest point of the leading slitting cutting edge (18) and which is set to extend obliquely forwards in the hauling direction, the slitting coulter (17) and the furrow breaker (21) being arranged in front of the drilling coulter.
