Komatsu America’s new GD655-5 motor grader features a new patent-pending
cab that offers unsurpassed all-around visibility. Even with the increase to 218 horsepower and 35,351 lbs, the fuel savings is 20 percent better than the model it replaced. This improvement is a result of Komatsu’s three-stage 2-mode engine technology. The engine also features a full hydraulic reversible fan.
