The Exact harrow can be used in conjunction with the RoTeC pro coulter system as well as the TwinTeC coulters. The Exact harrow tine has a thickness of 10 mm, is low-wearing and provides excellent 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.
The harrow pressure is adjusted mechanically by pre-tensioning the harrow springs. During hydraulic harrow pressure adjustment, a minimum and maximum value is predefined by inserting pins. 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.
The Exact harrow is particularly useful when sowing under less than optimal conditions, e.g. on moist or heavy ground.
