Designed for precision
Designed for smooth, powerful accuracy at your operator’s fingertips. A unique dual mode transmission with a torque converter and innovative stall prevention technology makes this motor grader easier to operate for operators of varying skill levels.
- Exceptional visibility
- Smooth power and optimized control
- High flow hydraulics with on-demand CLSS valves for operator efficiency
- Up to 15% increased fuel efficiency*
Note: *compared to GD655-5
Features and benefits
2D cross slope standard
Simplify road maintenance and easily maintain a desired cross slope angle when adjusting the blade cutting height. The main display and integrated control levers allow the operator to quickly select a predetermined slope angle.
Dual mode powershift transmission
Control, finesse and traction where it is needed — at the ground with our unique dual-mode transmission. Torque converter with stall prevention technology makes it easier to operators of varying skill levels.
Convenient control
The all-new, low-effort fingertip control levers provide quick response and precision, for new and experienced operators. Located on the powered armrests for ultimate comfort, arm movement is reduced up to 92%.
Designed for ease of operation
Put your operator in control. Equipped with both a right-sized steering wheel and steering lever to match operator preference and to reduce fatigue.
Fuel 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.
Reliability
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 new standard air suspension seat. The seat adjusts to the operator’s weight and dampens vibrations from the machine, reducing fatigue.
Smooth, efficient operation
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.
Ergonomic cab
Increase visibility to the moldboard heel and toe with the new hexagonal cab. The comfortable cab has enhanced ergonomics with adjustable seat, consoles, arm rests and controls.
