New GD955-7 is designed to build and maintain haul roads for truck fleets of 100 tons and up
Solid and smooth haul roads are essential for maximum productivity. To build and maintain them for fleets of 100 tons and up, Komatsu’s new GD955-7 motor grader offers operators the control and precision necessary.
The GD955-7 stands out with its 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.
“With significant increases in operating weight, blade downforce pressure, and working travel speeds, this new size class motor grader will be a smart choice for increased efficiency on our customer’s mine sites,” said Joseph Sollitt, Director of Mining Support Equipment at Komatsu.

Tight turning radius
Despite its large size, the GD955-7 offers excellent maneuverability. 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-degree articulation angle allow a tight turning radius and provide maneuverability for narrow haul road applications in confined spaces and around obstacles.
The newly adopted, 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.
“The GD955-7 comes standard with an 18-foot moldboard, and there is a 20-foot optional moldboard available,” said Sollitt. “We encourage anyone who has a larger fleet of trucks and wants to build and maintain their haul roads to contact their Komatsu distributor for additional information.”
