The W 200Hi milling machine has a hydraulically driven drum assembly that can be displaced 15.75 inches to the right or left. The unit is based on the W 200i/W 210i platform. The drum assembly can be moved while in operation, and it gives the machine a zero edge on both sides. The edge protector can be raised by 16.5 inches on both sides so the machine can work flush with the edge. The new W 200 Hi is powered by a Tier 4-Interim compliant 580-horsepower engine.
