The Cat 14M3 motor grader has a load-sensing system and advanced electrohydraulics that gives operators superior implement control and hydraulic performance.

The new Cat 14M3 motor grader builds on the solid design of predecessor models with a larger engine, increased fuel efficiency, improved machine balance, enhanced transmission performance, advanced electro-hydraulic steering, more powerful telematics, and added operator-safety/convenience features. An easily maintained drawbar-circle-moldboard assembly is designed for productive performance in a range of applications, and long-term durability of major structures combines with low operating costs and serviceability to provide optimum value.

The 14M3’s front frame is a single, heavy-duty steel casting designed to dissipate working forces, and the rear frame features two bumper castings and thick hitch plates. A series of patented, easily installed “top-adjust” metallic or nonmetallic wear strips and wear inserts ensure that drawbar-circle-moldboard components maintain a “factory-tight” condition that promotes high-quality work and significantly reduces operating costs. An adjustable circle drive also assists in maintaining assembly tightness and further reduces service time and costs.

The Cat C13 ACERT engine replaces the C11 engine in predecessor models and features an ECO mode that boosts fuel economy by limiting the engine’s high-idle speed to 1,750 rpm in working gears, while maintaining machine power. ECO-mode savings are especially significant when working at high idle in light to moderate applications in gears 3R to 5F.

The standard Optimized Variable Horsepower system is designed to closely match power requirements in all gears, and the Consistent-Power-To-Ground feature automatically changes engine power levels to compensate for cooling-fan losses, resulting in consistent power delivery in all ambient temperatures and working conditions. The C13 ACERT engine is available in three versions to suit emissions standards in the area of use. All emissions solutions are transparent to the operator and do not interrupt working cycles.

The 14M3’s 8F/6R power-shift transmission has a wide operating range for application flexibility and maximum productivity. The Cat Advanced Productivity Electronic Control System (APECS) enhances range-to-range shifting by maintaining consistent torque flow and smoothing shift points. The Shuttle-Shift feature enables directional shifts without slowing engine speed or using the inching pedal, and an available Autoshift system allows programming shift points to best match requirements of specific applications.

An engine-over-speed-protection system prevents downshifting at excessive ground speeds, and the standard automatic differential lock disengages during turns and re-engages during straight travel, simplifying operation and protecting the power train.

The 14M3’s load-sensing hydraulic system incorporates advanced electro-hydraulic operation for precise, responsive implement control. Proportional Priority Pressure-Compensating valves provide different flow rates for the head and rod ends of the cylinders, further ensuring consistent, predictable control. Balanced, proportional hydraulic flow enables all implements to operate simultaneously with consistent speed at consistent engine speeds.

A fully scalable, factory integrated Cat GRADE with Cross Slope system allows operators to easily maintain desired cross slope by automatically controlling one side of the blade. In addition, newly patented Stable Grade and Auto Articulation technologies improve operator performance and productivity. Stable Grade detects and reduces machine bounce during operation while Auto Articulation improves maneuverability and performance in tight working spaces and enhances operator comfort. Cat Advanced Control Joysticks are optional with Cat GRADE with Cross Slope, and they also allow precise operation with AccuGrade and when using snow wings. The Advanced Control Joysticks allow the operator to configure auxiliary hydraulic functions safely and effectively without removing either hand from the controls, which results in decreased operator fatigue and increased productivity.

More effective fleet management is placed in the machine owner’s hands with the Cat Product Link telematics system. The system allows remote monitoring of machine location, fuel usage, machine performance and fault codes via the secure VisionLink user interface.
