2024 Komatsu Motor Graders GD655-6
Next-level grading
Looking for smooth accuracy in an operator-friendly machine Powered by a unique dual-mode transmission, this grader has enhanced job site visibility and offers operators an exceptional tool for achieving surface precision.
Features may include:
Unique dual-mode powershift transmission with torque-converter- Control, finesse and traction where it is needed — at the ground. For fine finish grading at a steady speed or for precise cutting around objects, the industry exclusive, dual-mode transmission with anti-stall technology allows for steady efficiency.
- Efficient operation with two selectable power settings. For fine finish grading or light-duty road maintenance, eco mode helps provide fuel efficiency, while heavy pushing or high-demand tasks are tackled in power mode.
- Help protect the moldboard, drawbar and blade circle from damage with two selectable function blade accumulators. Blade lift cylinders absorb impacts if the blade edge hits an immobile object such as a manhole, boulder or railroad crossing.
- Long days on the job are more comfortable with the standard air suspension seat. The seat adjusts to the operator’s weight and dampens vibrations from the machine, helping to reduce fatigue.
- High-performance hydraulic system provides responsive control and smooth, constant speed. The closed-center load-sensing system allows for multiple circuits to operate simultaneously, independent of engine speed.
