The Komatsu GD555 Motor Grader

Equipped with a SAA6D107E-1 engine, the GD555 grader delivers 144kW of power. Not only is this motor grader powerful, it is EU Stage 3A certified. Without compromising on performance the GD555 has achieved low emissions.

This model is hydraulic driven and it is also fitted with an auto reversing cooling fan. At low temperatures these features function to decrease power loss. The other benefit is that the engine noise is also decreased. The regulation for the engine speed results in an impressive fuel consumption.

The 2 Mode 3 Stage VHPC system enables the operator to switch between two modes depending on the working conditions. P mode is useful in situations where the grader is facing high levels of resistance. E mode is suitable for light work conditions and it offers improved economy.

Komatsu’s Power Shift Transmission

Another advantage of finding a Komatsu grader for sale is its excellent transmission. The Power Shift Transmission has been developed especially for the company’s graders. The transmission offers full power shifting without interruptions. It also provides inching capabilities as well as automatic shifting in the top gears.

The operator has a choice between auto and manual mode which can be selected according to the working conditions. During challenging conditions or when precise control is necessary, auto mode is preferable.

If the situation requires faster speeds then the operator can switch to manual mode. The Komatsu GD555 has eight forward speeds as well as four reverse speeds. The Electronic Transmission Control helps to create an even grading surface while also reducing wear and tear on the transmission clutch.

Electronic Overspeed Protection reduces engine and transmission maintenance. The Low Effort Inching Pedal offers increased precision.

The hydraulic system heat is also reduced. The valves were developed to offer increased precision and decreased wear and tear. The ergonomic layout of the controls reduces driver fatigue and supports productivity. If the operator engages numerous switches simultaneously, the flow is adjusted accordingly. Implement speed is maintained even when the engine speed is varied.
