January 26, News 1 Views. The GD and GD graders combine the popular characteristics of the previous Dash 3 series with exciting new features that focus on high performance and fuel efficiency, operator comfort, safety and easy serviceability. At the heart of the new graders is a powerful, low emission and electronically controlled common rail injection SAA6DE-1 Komatsu engine.
The Komatsu-developed and manufactured power train further improves performances and lower operation costs, with a new torque converter drive combined with an automatic transmission. This prevents engine stall under heavy work conditions and allows easier, smoother operations at low speed.
Another essential point for graders is excellent blade controllability. Larger blade angles let material roll more freely along the blade, reducing blade load and increasing productivity. For safer and more comfortable operation, visibility of the mouldboard and of the front and the rear of the grader has been greatly improved thanks to a spacious hexagonal cab with wide windows in the doors. It also reduces noise levels and engine power loss. Refueling is easier and safer as it can now be done from ground level.
You can track them in the field and optimize their output through increased efficiency and pro-active maintenance. Quick specs :. Source: Komatsu News Room. Tags Komatsu News. Next Volvo CE breaks the ice and snow.Excellent performance with the GD Komatsu Grader. April 15, In the market for a top-notch grader for sale? Komatsu equipment is designed with the requirements of their customers in mind.
The Komatsu GD is a high performance, economic grader. Finding a reliable grader can enhance the productivity of your business. Komatsu manufactures all the major parts of their machinery. From engines to electronics, the main components of their machines are manufactured in-house.
Their dedication to customer satisfaction and continuous development contributes to the excellent performance of Komatsu equipment and machinery. The outcome of their efforts is quality machines which are also environment friendly. Not only is this motor grader powerful, it is EU Stage 3A certified. Without compromising on performance the GD 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. 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. Another advantage of finding a Komatsu grader for sale is its excellent transmission. 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 GD 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. In the market for a quality grader from Komatsu Equipment?
Another note-worthy element of the GD is its control features.As with all our graders, key components are designed and manufactured by Komatsu to work together in an integrated package.
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. 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. Komatsu graders feature a versatile moldboard geometry.

Due to economic conditions at the time, development was stalled for much of the s. The DA has a ground contact area of The DA-3 SD includes major changes to the frame, powertrain, undercarriage, and blade, making it substantially different from the DA In comparison to its predecessor, the DA-3 SD includes a significantly re-designed operator cabin and powertrain electronic control system to increase productivity and a number of durability improvements including reinforced undercarriage roller guards, simpler hydraulic plumbing and longer-life hoses, seals, wiring harnesses, and connectors.
Due to its immense size, the DA must be broken down into component form when it is moved from one job site to another. Moving all the components requires six to eight truck loads . From Wikipedia, the free encyclopedia. Arabe, Katrina C.
