GD955-7 Motor Grader Now Available to North American Market

The GD955-7 motor grader, now available to the North American market, offers operators control and precision to build and maintain haul roads for truck fleets of 100 tons and up.

This machine has ample horsepower and powerful blade downforce pressure for efficient grading performance. With faster working travel speeds compared to the previous model, Komatsu engineered the GD955-7 to increase grading efficiency while helping reduce maintenance requirements and total cost of ownership.

Despite its large size, it can execute tight U-turns on a standard 100-ton class haul road without the need to fully cut the wheel or course correct. The long wheelbase and large, 27-deg. articulation angle allows a tight turning radius and provides maneuverability for narrow haul road applications in confined spaces and around obstacles.

The long-life circle bearing allows for smooth and precise rotation of the moldboard while eliminating the need for circle play adjustments or replacing wear plates. Coupled with a standard auto-lubrication system, the GD955-7 is engineered to help reduce planned and unplanned maintenance downtime while helping to extend life to overhaul.
