More Comfort – More Performance – More Versatility

  • IMPROVED PERFORMANCE

    A Cat® C7.1 engine and powerful hydraulics give you the power to move your material with speed and precision.

  • UP TO 5% LOWER MAINTENANCE COSTS

    With extended and more synchronized maintenance intervals, you get more done at a lower cost compared to the previous model.

  • UP TO 45% INCREASED OPERATOR EFFICIENCY

    Work faster with improved rotational movement and lower DEF and fuel consumption. Optional Grade, Payload, and E-Fence technologies provide additional versatility, precision, and efficiency.

Engine

Biodiesel Capability Up to B20¹
Bore 4.1 in
Displacement 427.8 in²
Emissions Meets U.S. EPA Tier 4 Final, EU Stage V, Japan 2014 emission standards.
Engine Model C 7.1
Engine Power - ISO 14396 174 hp
Engine Power - ISO 14396 (DIN) 176 hp (metric)
Net Power - ISO 9249 171 hp
Net Power - ISO 9249 (DIN) 174 hp (metric)
Note (1) Net power advertised is the power available at the flywheel when the engine is equipped with fan, air cleaner, CEM exhaust gas aftertreatment, alternator, and cooling fan with engine speed at 2,200 rpm. Advertised power is tested per the specified standard in effect at the time of manufacture.
Note (2) ¹Cat diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) or ULSD blended with the following lower-carbon intensity fuels** up to: 20% biodiesel FAME (fatty acid methyl ester)* or 100% renewable diesel, HVO (hydrotreated vegetable oil) and GTL (gas-to-liquid) fuels.Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations“ (SEBU6250) for details. * Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel (for use of blends higher than 20% biodiesel, consult your Cat dealer).** Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels.
