EASY MAINTENANCE FOR MORE UPTIME
A series of patented top-adjust metallic or non metallic wear strips and wear inserts are easy to add or replace. This keeps drawbar-circlemoldboard components factory-tight for higher quality work, and saves you service time and costs. An adjustable circle drive reduces service time and reduces wear by keeping components tight.
The Cat C13 ACERT engine gives you the performance to maintain consistent grading speeds for maximum productivity. Superior torque and lugging capability pulls through sudden, short-term load increases.
Standard optimized variable horse power (VHP) is designed to provide the ideal amount of power in all gears to efficiently perform diverse motor grader applications while protecting structure and drive train components.
ENGINE ECONOMY (ECO) MODE
ECO Mode improves fuel economy by reducing high idle engine speed while maintaining machine power. ECO Mode controls the high engine idle speed (capped at 1,750 rpm in working gears) to ensure the engine is performing as efficiently as possible with respect to fuel consumption.
ECO Mode can provide significant fuel consumption savings especially in operations that are typically run at light to moderate loads, high idle and gear usage between 3R to 5F.
CONSISTENT POWER TO THE GROUND
This standard, automatically enabled, feature changes the engine power levels in real-time to offset cooling fan losses, resulting in consistent power to the ground independent of ambient temperatures and machine workloads. As a result, you will get the best performance from the machine all the time.
Emissions reduction technology on the 14M3 motor grader is designed to be transparent, with no action required from you. It delivers the same power and torque needed for optimal performance. The C13 ACERT engine variation with Tier 4 Final/Stage IV emission standards includes:
DIESEL PARTICULATE FILTER (DPF)
The Diesel Particulate Filter can provide a particulate reduction of greater than 90%. It filters soot from the exhaust then the soot is removed through the regeneration process automatically or manually.
SELECTIVE CATALYTIC REDUCTION (SCR)
The Selective Catalytic Reduction system can provide a NOx reduction of greater than 90%. SCR operation is transparent to the operator during operation. The urea solution, Diesel Exhaust Fluid (DEF), is pumped from the DEF tank and is sprayed into the exhaust stream. The DEF reacts with the SCR catalyst to reduce NOx.
DIESEL EXHAUST FLUID (DEF)
Diesel Exhaust Fluid is a liquid injected into the exhaust system of engines equipped with Selective Catalytic Reduction (SCR) systems. DEF that meets ISO 22241 specifications is required.
GROUND LEVEL DIESEL EXHAUST FLUID (DEF) FILL
The 14M3 DEF fill allows the DEF tank to be conveniently filled from ground level. Simply refill the DEF tank when you refuel.
Maximum power to the ground
The front axle steering cylinder and sensing guards have been designed to enhance durability and hydraulic hoses have been routed to improve reliability.
Optional heavy and light duty front guards are available to help protect the front axle from rocks or other debris that could damage the axle or its components.

Eight forward and six reverse gears are specifically designed to give you a wide operating range for maximum productivity.
Engine Over-Speed Protection prevents downshifting until an acceptable safe travel speed has been established.
FRONT AND REAR AXLES
The sealed spindle keeps front axle bearings lubricated and protected from contaminants. The Cat “Live Spindle” design places the larger tapered roller bearing on the outside, where the load is greater, extending bearing life.
A bolt-on modular rear axle improves serviceability and contamination control with easy access to differential components.
Oil-bathed, multi-disc service brakes are hydraulically actuated for smooth, predictable braking and lower operating costs. Brakes are located at each tandem wheel for a large total brake surface area to give you dependable stopping power and longer life.
EASE OF OPERATION
Two electro-hydraulic joysticks reduce hand and wrist movement up to 78%, compared to conventional lever controls, resulting in greatly enhanced operator comfort and efficiency. The intuitive control pattern allows both new and experienced operators to quickly become productive. Electronically adjustable control pods help position joysticks for optimal comfort, visibility and proper operation.
With the touch of a button, the articulation return-to-center feature automatically returns the machine to a straight frame position from any angle.
You can choose the blade lift modulation mode that best fits your application or operating style: Fine, Normal or Coarse.
Electronic throttle control provides easy, precise and consistent throttle operation.
Good visibility is key to your safety and efficiency. The 14M3’s large windows provide exceptional visibility while an optional rear vision camera can further enhance your lines of sight to the rear of the machine.
COMFORT AND CONTROL
Experience the most spacious, comfortable cab in the industry. Revolutionary joystick controls replace conventional levers and steering wheel, helping to reduce operator fatigue. Moreover, Advanced Control Joysticks, a patented interface, improve operational efficiency, boost productivity levels and enhance operator comfort are available as an option.
Now conveniently located in the center console, a message display shows machine and diagnostic information in addition to Cat GRADE with Cross Slope readings. The keypad allows activation and deactivation of different functions in the machine with one touch and indicates whether a function is active or not through light emitting diode (LED) lights.
The standard mechanical suspension seat has side bolsters that restrain side‐toside movement especially when working on side slopes. Multiple isolation mounts significantly reduce sound and vibration for a more relaxed work environment. An optional heated and ventilated seat provides enhanced comfort for operators in extreme weather conditions.
The high capacity Heating, Ventilation and Air Conditioning (HVAC) system dehumidifies and pressurizes the cab, circulates fresh air, seals out dust and keeps windows clear.
Additional storage space for commonly used cabin items is included inside the cab.
Optional Bluetooth™ and satellite radio are available.
Advanced machine controls with precise and predictable movements.
LOAD SENSING HYDRAULICS (PPPC)
A proven load-sensing system and advanced Proportional Priority Pressure-Compensating (PPPC) electro-hydraulic valves give you superior implement control and enhanced machine performance. Continuously matching hydraulic flow/pressure to power demands creates less heat and reduces power consumption.
Consistent, Predictable Movement – PPPC valves have different flow rates for the head and rod ends of each cylinder, so you can count on consistent, predictable implement response.
Balanced Flow – hydraulic flow is proportioned to give you confidence that all implements will operate simultaneously without slowing the engine or speed of some implements.
Allows the blade to move freely under its own weight. By floating both cylinders, the blade can follow the contours of the road. Floating only one cylinder permits the toe of the blade to follow a hard surface while the operator controls the slope with the other lift cylinder.
INDEPENDENT OIL SUPPLY
Large, separate hydraulic oil supplies prevent cross-contamination and provide proper oil cooling which reduces heat build-up and extends component life.
