Seed coverage with the Exact harrow
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 depth guidance is centrally adjusted mechanically via two spindles. A minimum and maximum value is predefined for the hydraulic harrow pressure adjustment (optional) by inserting pins. This enables both the harrow pressure and the coulter pressure to be adapted to changing soil conditions during operation by means of just one tractor control valve.
The 15 mm thick Exact S following harrow is used in conjunction with the RoTeC+ Control coulter. It is low-wearing and provides good seed coverage, even in most difficult of operational conditions.
