Articulated Motor Grader

For Release in North America and Europe: November 2015
Release Number: 344PR15

Caterpillar introduces a suite of integrated technologies for M Series, M Series 2 and M Series 3 Motor Graders: Cat® GRADE with Cross Slope, Stable Grade, Auto Articulation and Advanced Control Joysticks. The four technologies improve operator performance and productivity while reducing operating costs.

Cat GRADE with Cross Slope: Fast, accurate grading

Cat GRADE with Cross Slope is an optional factory-integrated system that requires no infrastructure, base station, design files or data radios. Simple and cost effective, this 2D system automatically adjusts the slope of the blade based on the operator’s input, instantly delivering a uniform elevation change across the cutting edge. As a result, operators can get to grade quickly and accurately with less fuel, materials and effort. When 3D control is required, the system can be easily upgraded to AccuGrade™.

Stable Grade: Less bounce, more precision

Stable Grade is an optional patented technology that detects and reduces machine bounce to improve grading precision. The system automatically decreases engine speed at 15 percent intervals whenever machine bounce is detected. As the grader stabilizes, engine rpm increases systematically until a pre-set level is reached. Settings can be adjusted to match site conditions or operator preferences.

Auto Articulation: Improved maneuverability and productivity

Auto Articulation, another patented technology, allows the motor grader operator to articulate automatically while steering, greatly reducing fatigue. The result is improved productivity and maneuverability, particularly when working in tight spaces or around curves, obstacles and turnarounds. All M Series and M Series 3 motor graders come from the factory with Auto Articulation hardware installed and a 500-hour software trial.

Advanced Control Joysticks: Safe, efficient control

Advanced Control Joysticks allow operators to steer, shift, articulate, adjust the blade, use Cat GRADE with Cross Slope, operate a snow wing and control auxiliary hydraulics—without taking their hands off the joysticks. Easy to learn and use, these optional controls enhance safety, reduce fatigue and improve operator productivity.
