Our GD555-5 144 kW grader features outstanding visibility to the blade and work areas, as well as Komatsu’s unique dual mode transmission system that provides the option of full powershift or lockup automatic torque converter. As with all our graders, key components are designed and manufactured by Komatsu to work together in an integrated package. And it comes standard with our Komtrax remote monitoring and location system, backed by our Australia-wide service and support network.

    Features and benefits

    High performance Komatsu engine

    High performance Komatsu engine

    Electronic heavy duty common rail fuel injection system provides optimum combustion of fuel. This system also provides fast throttle response to match the machine's powerful tractive effort and productivity.

    Power on demand

    Power on demand

    Normally, the variable displacement pump idles at low output. When it senses a load requirement, the pump supplies quick flow and pressure to match the demand. The result is less hydraulic system heat, quick response and lower fuel consumption. The bottom line is greater efficiency.

    Versatile moldboard geometry

    Versatile moldboard geometry

    Komatsu graders feature a versatile moldboard geometry. Save time and money when pulling ditches by throwing the windrow to the right, not the roadway - without narrowing the road bed. It's made possible by Komatsu's extraordinary reach and aggressive blade angle.
