D6T, D7E and D8T dozers are not only powered by Cat ACERT engines designed to meet Tier 4-I emissions standards, but also have new features. Net horsepower ratings range from 205 to 310; and engines use Cat NOx-Reduction System, Cat Clean Emissions Module and Cat Regeneration System. All three models are grade-control ready with integrated harnesses from the factory. Cab interiors feature streamlined dash displays and instrumentation. The D6T and D7E offer Eco Reverse Mode, which reduces fuel consumption when the tractor reverses; the D8T’s Enhanced Auto-Shift is said to reduce fuel consumption by up to 6 percent in certain applications.
The Cat 336F H Hybrid hydraulic excavator will soon be powered by a Tier 4-Final Cat C9.3 ACERT engine rated at 303 horsepower.
The new Cat 966M, 966M XE, 972M, and 972M XE wheel loaders meet Tier 4-Final emissions regulations with a combination of combustion strategies and after-treatment components.
