  • Engine technology reduces emissions, lowers combustion chamber temperatures and optimizes combustion to generate more work output from every unit of fuel.
  • Hydraulic demand fan automatically adjusts according to engine cooling requirements. When cooling demand is reduced, you benefit from more power to the ground and improved fuel efficiency.
  • Engine Idle Shutdown feature can be software-enabled by your Cat dealer to shut down the engine after a set period of time to save you fuel and help reduce emissions.
  • M Series Motor Graders to give you efficiency and stand up to the most demanding applications:
  • Standard Automatic Differential Lock/Unlock unlocks the differential during a turn and re-locks when straight for easier operation and to help protect the power train.
  • Full Electronic Clutch Pressure Control system optimizes inching modulation for smooth shifts and directional changes, reducing stress on gears.
  • Programmable AutoShift option simplifies operation by allowing the operator to program the transmission to shift at optimal points to match each application.
  • Power Shift Countershaft Transmission is matched to the Cat engine to maximize power to the ground.
  • Wide operating gear range for maximum productivity.
  • Engine Over-Speed Protection prevents downshifting until an acceptable safe travel speed has been established.
  • Sealed spindle keeps front axle bearings lubricated and protected from contaminants. Cat “Live Spindle” design places the larger tapered roller bearing on the outside, where the load is greater, extending life.
  • Bolt-on modular rear axle improves serviceability and contamination control with easy access to differential components.
  • Oil-bath, multi-disc service brakes are hydraulically actuated for smooth, predictable braking and lower operating costs. Brakes are located at each tandem wheel and have a large total brake surface area to provide dependable stopping power and longer life.

HEAVY DUTY CONSTRUCTION

  • One-piece forged steel circle stands up to high stress loads, and a sacrificial wear system helps keep your service time and costs down.
  • Articulation hitch features a large tapered roller bearing to carry loads evenly. The bearing is sealed preventing contamination and a locking pin prevents articulation during service or transport.
  • The M Series drawbar, circle and moldboard are designed to make it easy for you to keep the components tight.
  • Shims and patented top-adjust wear strips are easy to add or replace, dramatically reducing downtime.
  • Nylon composite wear inserts maximize circle torque and component life.
  • Sacrificial brass wear strips between the blade mounting group and moldboard can be easily adjusted and replaced.
  • Shim less Moldboard Retention System uses vertical and horizontal adjusting screws to keep moldboard wear strips aligned for reduced blade chatter and precise control.
  • With an aggressive blade angle, optimized moldboard curvature and large throat clearance, you work more efficiently by allowing material to roll more freely along the blade.
  • Heat-treated rails, hardened cutting edges and end bits, and heavy duty bolts provide greater moldboard reliability and long service life.
  • Link bar allows extreme moldboard positioning for easier bank sloping and ditch cutting/cleaning.
  • Proven load-sensing and advanced electro-hydraulics give you superior implement control and responsive hydraulic performance that makes operators' jobs easier.
  • Continuously matching hydraulic flow/pressure to power demands reduces heat and optimizes power.
  • Proportional Priority Pressure-Compensating (PPP-C) valves have different flow rates for the head and rod ends of the cylinder, so you can count on consistent, predictable implement response.
  • Hydraulic flow is proportioned to give you confidence that all implements operate simultaneously without slowing engine or implement speed.
  • Blade Float allows the blade to move freely under its own weight.
  • Float both cylinders, to allow blade can follow the contours of the ground.
  • Float one cylinder to permit the toe of the blade to follow a hard surface while the operator controls slope with the other cylinder.
  • Large, independent hydraulic oil supplies prevent cross-contamination and provide proper cooling, reducing heat build-up and extending component life.
  • Cat XT™ hose allows high pressures for maximum power and reduced downtime.

TECHNOLOGY THAT GETS WORK DONE

  • Grade technologies combine digital design data, in-cab guidance, and automatic blade controls to enhance grading accuracy, reduce rework, and lower costs related to production earthmoving and rough, fine and finish grade applications.
  • Cat GRADE with Cross Slope is an optional, fully integrated, factory installed system that helps operators maintain desired cross slope by automatically controlling one side of the blade. System is job-ready from day one, and scalable for the future with AccuGrade™ upgrade kits that provide additional 2D and/or 3D control.
  • AccuGrade Attachment Ready Option can be ordered as a factory- or dealer-installed option. Includes built-in mounting points and internal wiring, to facilitate installation of AccuGrade grade control system.
  • AccuGrade uses positioning and guidance technologies, machine sensors, and automatic blade control to help operators get to grade faster, easier and more efficiently.
  • In-cab guidance gives operators detailed information to work confidently and achieve greater accuracy, in fewer passes, using less material.
  • Operators can stay on grade and improve productivity and accuracy by nearly 50 percent over conventional methods.
  • Grade stakes and checkers are minimized, helping to make the work site safer and more cost effective.
  • AccuGrade technologies include Cross Slope, Sonic, Laser, GPS, and/or Universal Total Station (UTS).
  • Optional Stable Blade system detects bounce through an accelerometer and reduces engine rpm as required at 15 percent intervals to stabilize machine bounce. Once the motor grader has stabilized, Stable Blade will increase engine speed back to the initial set level. The throttle will not be reduced below 1,200 rpm.
  • Cat Product Link™ Elite takes guesswork out of equipment management with remote monitoring capabilities for one machine or an entire fleet.
  • Tracks asset location, hours, fuel usage, diagnostic codes, idle time and more through the secure VisionLink™ user interface.
  • Knowing where your equipment is, what it's doing and how it's performing enables you or your Cat dealer to manage your fleet in real-time so you can maximize efficiency, improve productivity and lower operating costs.*
