The R and RGS series are made up of approved towed agricultural operating machines, foldable using hydraulic devices, equipped with cylindrical metal rollers ballasted with water for leveling and compacting agricultural soil. In the R models the cylinders are overturned by 90° and rotated longitudinally in order to fit within the maximum dimensions allowed for road trailers. In the RGS models the cylinder rotates 90° transversally while the wheels lower at the same time in order to fit within the maximum overall dimensions allowed for road trailers. A hydraulic device mounted on the eye allows you to adjust the height of the drawbar during the transport phase. All hydraulic jacks are equipped with safety devices (block valve)
