GD655-6 Motor Grader

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.

Komatsu’s Dual-mode transmission sets this grader apart from its competition.  The Dual-mode transmission has been specifically designed for use in Komatsu motor graders. It allows operators to benefit from the low-fuel consumption and high ground speeds of a direct-drive transmission, as well as the high tractive effort, superior control at low speed, and anti-stall features of a torque converter transmission.
