From Compacter Rollers
The new R series is constituted of road-worthy approved agricultural machines that can be compacted by means of hydraulic devices, and are equipped with metallic cylinders that can be weighted with water, for the levelling and compacting of the farmland. In the R models, the cylinders can be turned 90° in a longitudinal direction in order to fit within the maximum encumbrance limits allowed for road trailers. The height of the shaft can be regulated during transport by means of a hydraulic device fitted onto the ring. All the hydraulic jacks are equipped with safety devices (block valves).
