Hexangular-shaped cab provides greater visibility for Komatsu grader

Komatsu’s GD655-5 motor grader is powered by their 218-hp SAA6D107E-1 engine and has a standard configuration weight of 35,351 pounds. The power train design positions the engine at the rear of the machine, which – along with the increased weight on the front axle – provides better control.

Komatsu engine technology provides a three-stage, 2-mode system that produces higher power with reduced fuel consumption. The three-stage system offers three levels of power from gear one through gear eight, producing more productivity with a 20 percent fuel consumption savings when compared to the previous model, and there is a choice of economy mode or power mode, depending on the work application. 

The Komatsu new dual-mode power shift transmission is designed and built specifically for Komatsu graders. The dual-mode provides a lockup torque converter mode as well as a direct drive mode. There is a new anti-stall mode for direct drive. Before the grader stalls in a low speed application, the transmission shifts to the torque converter mode ensuring operator control.

In addition to a nine percent power increase, the weight of the base machine has been increased eight percent. The additional weight and increased wheelbase add up to more stability, easier blade positioning and greater productivity.

The Komatsu-designed cab has a hexangular shape that eliminates the front corner pillars, which allows for greater visibility. With a 21 percent larger cab, the operator has extra leg room and a low noise level of only 74dB(A). The console mounted hydraulic controls are arranged in the industry standard pattern on each side of the steering wheel, with Komatsu-designed control valves built specifically for graders.

The new GD655-5 has been designed for quick and easy maintenance. The tandem now does not require greasing.

New Cat® M Series 3 Motor Graders Deliver Greater Fuel Efficiency

The new Cat® M Series 3 motor graders—12M3, 140M3, 160M3 and their all-wheel-drive (AWD) counterparts—bring the latest emissions reduction technology to the most durable, productive and comfortable graders on the market. The new models offer greater fuel efficiency, more operator comfort and safety features, as well as enhanced serviceability. M Series 3 motor graders meet U.S. EPA Tier 4 Final/EU Stage IV emission standards.

Fuel Efficiency and Emissions Reduction
M Series 3 motor graders meet U.S. EPA Tier 4 Final/EU Stage IV emission standards using emissions reduction technology that is designed to be transparent, with no action required by the operator. There is no need to stop for regeneration. The system uses Caterpillar’s proven aftertreatment solution with the addition of Selective Catalytic Reduction (SCR). SCR utilizes Diesel Exhaust Fluid (DEF), which can be conveniently filled from ground level when the machine is fueled. Because of improved fuel economy over Tier 4 Interim and efficient use of DEF, M Series 3 motor graders deliver excellent overall fluid efficiency.
