<p>The device has a cross beam (1) that is coupled to a towing vehicle transversely to the direction of travel of vehicle. The liquid manure discharge nozzles (3) and associated disc coulters (4) are supported at the cross beam. A support is more swingable around axles vertical to soil surface, so that the disc coulter is adjustable with different angles to the direction of travel of vehicle in the range of +- 5-+- 20/[deg] by mechanical or hydraulic adjustment device.</p> |
