Technical Description

The Komatsu GD655A-2 is a mid-sized motor grader powered by a Cummins NH220-CI diesel engine producing 165 horsepower and 550 lb-ft of net torque. With a total operating weight of 29,101 pounds and overall length of 27.7 feet, this machine offers balanced performance for road construction and maintenance applications. The 13.2-foot moldboard features a maximum cutting depth of 22.5 inches and lift height of 15.8 inches, enabling precise grading operations. The machine operates on 13.00-24-10PR tires with a 22.7-foot turning radius and 25-degree articulation angle for enhanced maneuverability on job sites. Equipped with a Hydroshift transmission, the GD655A-2 delivers six forward and six reverse gears, achieving maximum speeds of 27.1 mph forward and 32.1 mph reverse. The front axle provides 2 feet of ground clearance with 30 degrees of total oscillation and 23 degrees of wheel lean for superior traction and stability on uneven terrain. The Isomount cab reaches 19.7 feet high, offering operators an elevated vantage point. The 743-cubic-inch engine displacement combined with the hydroshift transmission ensures responsive hydraulic control and efficient operation across varying workloads, making this grader suitable for general-purpose road work, maintenance, and light construction projects.
