Cat 14M3 motor grader bigger and better than predecessor
July 28, 2016 by On-Site Magazine
The 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 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.
