The maintenance-free, scalloped concave discs have a diameter of 400 mm and are mounted on rubber elements to protect them against obstacles such as stones. Each pair of discs is guided by the rear roller and are adjusted automatically when the working depth is changed. So you do not need to adjust the working depth again.

Fine adjustment of the concave discs is carried out by means of easily accessible spindles. Once set, the working results are consistent regardless of the depth setting.
