Whether in stubble, in grassland or in ploughed fields, RS is an efficient 3-bank stubble cultivator that works down to 15 or 30 cm depth on one or two passes. RS achieves intensive mixing of plant residues and earth, while the finishing work is performed by a disc gang, which leaves a leveled surface. Specially curved shanks equipped with quick hitch reversible double diamond points and overload secured via shear bolts. Working widths from 230cm to 350cm and for tractor power from 90hp to 180hp. The attach angle of the rear disc gang is infinitely adjustable and the working depth is hydraulically controlled (optional).
