Komatsu America Corp. - GD655-6 Motor Graders

With the longest wheel base in its class, the new GD655-6 offers exceptional fine grading performance. Even with a long wheelbase, the GD655-6 maintains a tight minimum turning radius, thanks to a maximum articulation angle of 25 degrees. This grader is extremely maneuverable and productive in tight road work or cul-de-sac applications. Thanks to the new, Komatsu designed, Tier 4 Final power plant, GD655-6 owners should see a drop in fuel consumption of up to 5% when operating in “power” mode, and up to 15% in “economy” mode, compared to the GD655-5.
