New Komatsu GD655-6 Motor Grader for Sale 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.
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. Fuel efficiency power modes: 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. Blade lift accumulators standard: 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. Operator comfort: 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. CLSS constant implement speed multi-circuit capable hydraulics: 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. Hexangular cab: Increase visibility with a commanding view of the job site. The hexangular, low-profile cab layout offers a wide field of vision, increasing the front and rear work equipment views. Rearview camera: Make sure your operator can keep an eye on the surroundings. The standard rearview monitor system and dedicated display with custom settings means that the main monitor is always showing important machine information. Hydraulic-driven cooling fan: Run the fan only when needed, for increased efficiency and power. A hydraulic cooling fan senses engine load and temperature adjusting fan speed as necessary. Actionable insights: Keep track of your machine and its productivity with the latest Komtrax system. Receive service alerts, operating history, faults, and fuel usage reports remotely by anyone granted user access. |
