The RWM/SSL is a disc-type road planer for skid steers from 75 to 135 hp, able to shred channels up to 20 in deep with modular widths of 3.2, 4 or 4.7 inches. The RWM/SSL aims mainly to ensure extremely precise excavations for laying electrical, water, gas and fiber optic conduits. The depth indicator allows precise depth management and the self-leveling penetration skids allow the working depth to be kept constant at all times. The optimized side output allows the track to be kept free of waste materials at all times.
