2020 Komatsu GD655

In-depth analysis of the core advantages of Komatsu GD655 motor grader
As the flagship product of ultra-large self-propelled motor graders, Komatsu GD655 is specially designed for high-precision leveling projects such as national infrastructure projects, large mines and airport runways, setting new industry standards in construction efficiency, intelligent control and adaptability to extreme working conditions. The following are its revolutionary advantages:

1. Super strong power system (industry leading)

🔥 Komatsu SAA6D170E-7 twin-turbocharged engine

447kW (600 horsepower) peak power, in line with Tier 4 Final/Stage V emissions

Dynamic torque management: 35% increase in torque at low speed (2500N·m output at 1800rpm)

Unique fuel dual injection system, fuel consumption under heavy load conditions is 18% lower than that of competitors

⚡ 8-speed intelligent transmission

Terrain adaptive shifting technology: automatically adjusts the transmission ratio to match the ground hardness

Zero power loss locking technology of torque converter

2. Military-grade structural design
