One of the unbeatable advantages of the RoTeC pro single disc coulter is that the reconsolidation is decoupled from the coulter depth control. This means that the coulter is raised only once when passing a stone. Furthermore, the coulter and roller pressure can be adjusted independently of each other. This very even and accurately controlled way of guiding the RoTeC pro single disc coulter is ensured by the Control 10 depth guidance roller, with its 10 mm wide contact area, or the Control 25 depth guidance roller, with its 25 mm wide contact area, directly on the coulter. The basic setting of the sowing depth takes place without tools and in 4 levels directly on the coulter.
