<p>The device (1) has multiple cutting knives (5) rotated around a longitudinal axis and attached at a supporting frame (4) of a spray truck (3). The cutting knives are height-adjustably aligned at a distance to a base (2) and arranged parallel to the base. Multiple hydraulically or pneumatically driven pistons (7) are attached between the supporting frame of the spray truck and a frame that supports the cutting knives. The pistons are connected with the tractor, where distance between the cutting knives and the base is adjusted by the pistons.</p> |
