Cat M Series Motor Graders 14M3
Product Feature
Technology
Optional Stable Blade improves grading precision by decreasing engine speed at 15 percent intervals when machine bounce is detected then increases engine rpm systematically when grader stabilizes.
Optional Cat GRADE with Cross Slope helps maintain desired cross slope by automatically controlling one side of the blade.
Optional Cat AccuGrade™ uses positioning and guidance technologies, machine sensors, and automatic blade control to help get to grade faster, easier, and more efficiently.
Optional Auto Articulation allows you to articulate automatically while steering in tight spaces or around curves, obstacles, and turnarounds.
Performance
Cat C13 ACERT™ engine meets U.S. EPA Tier 4 Final/EU Stage IV, Tier 3/Stage IIIA equivalent or Tier 2/Stage II equivalent emission standards, depending on emission standards of specific country.
Standard Economy Mode can be turned on to limit maximum engine speed which helps reduce fuel consumption.
Standard VHP Plus provides ideal amount of power in all gears.
Standard Automatic Differential Lock unlocks differential during a turn and re-locks when straight for easier operation and improved power train protection.
Efficiency
Load-sensing system and advanced electrohydraulics give operator superior implement control and hydraulic performance.
Proportional Priority Pressure-Compensating valves have different flow rates for head and rod ends of cylinder so machine responds consistently and predictably.
Balanced hydraulic flow is proportioned to ensure all implements will operate simultaneously without slowing engine or speed of some implements.
Ease of Operation
Simple, intuitive joystick controls replace levers, so hand and arm movement is reduced by 78%, helping reduce operator fatigue.
Optional Advanced Control Joysticks allow operator to control automated grading solutions efficiently and safely without removing hands from the joysticks.
Selectable blade lift modes – Fine, Normal, or Coarse – allow operator to match application requirements.
Articulation Return-to-Center automatically returns machine to a straight frame position from any angle with the touch of a button.
Safety
Optional rear vision camera enhances sight to rear of machine.
Electrical disconnect and engine shutoff switches are ground level.
Operator Presence System keeps parking brake engaged and hydraulic implements disabled until operator is seated and machine is ready for operation.
Hydraulic Lockout disables all implement functions while still providing machine steering control – especially useful while roading.
Optional seat belt indicator promotes safe operating habits.
Serviceability
Convenient access from the top of the circle to the patented top-adjust wear strips and inserts make them easy to add or replace.
Shimless Moldboard Retention System uses vertical and horizontal adjusting screws to keep moldboard wear strips aligned for reduced blade chatter and precise blade control.
Product Parameter
Overview
Cat® Motor Graders continue the Caterpillar tradition of being the industry standard in heavy construction, road building, and governmental applications. The 14M3 features a host of integrated technology solutions that increase operator efficiency, boost productivity levels and lower owning and operating costs. The 14M3 takes advantage of a larger engine, increased fuel efficiency, improved machine balance, enhanced transmission performance, more powerful telematics and added operator safety/convenience features.
