Seed coverage with the Exact harrow or with the Exact harrow S

The Exact harrow covers and levels the open seed furrow without blockage even with large amounts of straw present. 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.

The harrow pressure is centrally adjusted mechanically via two spindles. During hydraulic harrow pressure adjustment, a minimum and maximum value is predefined by inserting pins. This way both the harrow and the coulter pressure are linked together and so can, during operation, be adapted to changing soil conditions by the use of just one tractor control valve.

In conjunction with the RoTeC⁺ coulter, the 15 mm strong Exact S following harrow can be used. It gives little wear and provides good seed coverage even in most difficult of operational conditions.
