The Exact following harrow can be operated in conjunction with both RoTeC pro coulters and with the TwinTeC coulter system. The 10 mm tines on the Exact following harrow give little wear and provide a good seed coverage. The Exact following harrow serves for both coverage of the open seed furrows and for levelling. It operates, even where there are large amounts of surface straw, blockage free. With its individually pivoting harrow elements, the Exact harrow follows the undulations of the soil perfectly, ensuring an even seed coverage on soils either with or without straw. When sowing under less than the optimum conditions, e.g. on moist and heavy soils, the Exact following harrow pays off. The harrow pressure is adjusted mechanically by pre-tensioning the harrow springs. When equipped with the optional hydraulic harrow pressure adjustment, locating pins predetermine the minimum and maximum settings. So, the harrow pressure and the coulter pressure can be simultaneously matched to changing soils via just one tractor spool valve whilst on the move.
