Each individual disc is suspended from the frame on elastic sprung rubber buffer blocks across all models. This is much better than in machines with a rigid disc suspension, as each concave disc can individually follow the ground contours, meaning that wheel tracks are not simply just filled in but worked intensively. This makes for a consistent shallow tillage, even if the soil surface is uneven. At the same time, the individual suspension of the discs enables the optimum passage of large amounts of organic matter in comparison to machines where the discs are mounted in pairs, thereby increasing the through-flow.
