One of the unique features of the Cat grader 14h engine is the variable horsepower arrangement, which matches the torque curves to the gear, to maximize response, power, and efficiency. The variable horsepower option uses specific torque curves for each gear range for optimum performance. The base power is 238 HP (178 kW) for gears 1-3, and the maximum power is 264 HP (197 kW) for gears 4-8.


The engine also features a low fuel consumption rate, which reduces operating costs and environmental impact. The Eco Mode option saves fuel while maintaining productivity by automatically adjusting the engine speed based on the load. The engine also meets the current and anticipated regulations for emissions, exhaust, and noise levels, thanks to its advanced design and technology.


Power train




The power train is the system that transfers the power from the engine to the wheels and the blade. The Cat grader 14h has a power shift transmission that takes full advantage of the powerful engine. The transmission has eight forward and six reverse gears, with a maximum forward speed of 45.5 km/h (28.3 mph) and a maximum reverse speed of 36.6 km/h (22.7 mph).


The transmission also features an electronic clutch pressure control system, which modulates clutch engagement for smooth shifts and long clutch life. The transmission control lever allows the operator to select the direction, speed, and gear range with ease. The transmission hold feature enables the operator to maintain a selected gear for consistent grading.


The Cat grader 14h also has a dual air system and multi-disc oil brakes that assure reliable braking control. The dual air system consists of two independent air compressors and reservoirs that provide redundancy and safety. The multi-disc oil brakes are hydraulically actuated and fully enclosed to protect them from contamination and wear. The brakes are located at each tandem wheel to provide balanced braking.


Another feature of the Cat grader 14h power train is the differential lock and all-wheel drive options that enhance traction and maneuverability in difficult terrain or conditions. The differential lock is a hydraulically actuated clutch that locks both rear wheels together for increased traction. The all-wheel drive option provides additional power to the front wheels for improved steering and grading performance.


Hydraulics




The hydraulics is the system that controls the movement and position of the blade and other attachments. The Cat grader 14h has a load-sensing hydraulic system that lowers power consumption and system heat by delivering only the required amount of hydraulic flow and pressure to each function.


The hydraulic system also features advanced proportional priority pressure-compensating (PPPC) control valves that provide low lever effort, balanced flow, and consistent cylinder speeds for outstanding blade control. The PPPC valves have nine functions: blade lift, blade angle, blade side shift, circle drive, circle side shift, articulation, wheel lean, ripper lift, and ripper tip.


One of the benefits of the PPPC valves is the blade float feature, which allows the blade to move freely under its own weight. This feature improves grading quality by following the contours of the ground and reducing the number of passes required. The blade float is incorporated into the blade lift valves and can be activated by moving the blade lift lever to the full raise position.


Structures




The structures are the components that support and connect the engine, power train, hydraulics, operator's station, and other parts of the motor grader. The Cat grader 14h has a robust and durable frame, drawbar, circle, and moldboard that are designed and built to withstand the tough loads and stresses of grading operations.


The frame consists of two main sections: the front frame and the rear frame. The front frame supports the engine, operator's station, front axle, steering cylinders, and other components. The rear frame supports the transmission, rear axles, tandems, fuel tank, ripper or scarifier, and other components. The front and rear frames are connected by a heavy-duty articulation hitch that allows 20 of articulation for steering.


The drawbar is a forged steel component that connects the circle to the front frame. It transfers blade forces from the circle to the main frame as a torsional load. It also supports auxiliary equipment such as rippers or scarifiers.


The circle is a fabricated steel component that attaches to the drawbar with six shoes that allow it to rotate 360. It supports Operator's station




The operator's station is the place where the operator controls and monitors the motor grader. The Cat grader 14h has an ergonomic design and layout of the controls, gauges, and monitors that provide world-class operator control and comfort. The operator's station also offers improved visibility and comfort of the operator's seat and cab.


The controls are arranged in a logical and intuitive manner, allowing the operator to operate the motor grader with ease and precision. The low effort blade controls are located on the right side of the seat, and consist of two joysticks that control all blade functions. The electronic throttle control is located on the left joystick, and allows the operator to adjust the engine speed with a touch of a button. The transmission control lever is located on the left side of the steering wheel, and allows the operator to select the direction, speed, and gear range.


The gauges and monitors are located on the front console, and provide the operator with vital information about the motor grader's performance and condition. The electronic monitoring system III (EMS III) monitors all critical machine functions and alerts the operator of any problems or faults. The EMS III also displays fuel level, engine speed, gear selection, brake pressure, hydraulic oil temperature, articulation angle, and other parameters.


The visibility and comfort of the operator's seat and cab are enhanced by several features. The large windows and tapered engine hood ensure a clear view in all directions. The contour series suspension seat is adjustable to suit the operator's preference and posture. The seat also has a retractable seat belt for safety. The cab is spacious and well-ventilated, with an air conditioning and heating system that maintains a comfortable temperature. The cab also has a radio-ready entertainment system that includes speakers, antenna, and wiring for a radio or CD player.


The integrated technologies are another feature of the Cat grader 14h operator's station that improve grading accuracy and efficiency. Some of these technologies are:
