<p>The method consists of using a machine which decompacts and aerates the surface layer of the soil by making a series of furrows 4-12 mm wide and 6-15 cm deep, spreading the soil taken from the furrows evenly over the surface, drilling the grass seeds, raking the surface and rolling. The furrows are made by an implement (6) which penetrates the soil and rotates in the opposite direction to that of the machine's travel, and is equipped with tools (13) to decompact the substrate and crumble the soil taken from the furrows. After drilling the seeds the soil is raked by tools (10, 11) which reciprocate across the direction of travel, and is then rolled.</p> |
