The solution for surface stubble ploughing: the intensive mulching of crops’ residues and the destruction of plant covers. La gamme DDI se compose de 6 modèles traînés de 4m70 à 9m50. The DDI product range offers 6 towed-models going from 15’ 4’’ (4m70) to 31’ 2” (9m50). The discs are concave and corrugated, thus maximising the mixing and cutting of the residues. The disc pressure reaches about 150kgs, thus ensuring a constant working depth with no tapping effects. The disc harrow remains steady while working because the axle is in the centre of the chassis. Finally, the depth’s setting is hydraulic from the drivers’ position.
