More Comfort – More Performance – More Versatility


    Work faster with more swing torque. A smaller front and reduced tail swing radius lets you work in space-restricted areas.


    Longer, synchronized service intervals, 100% daily ground-level maintenance and centralized grease points with an autolube option lower your overall costs.


    Operate with ease. Easy to reach controls, a comfortable seat, and improved visibility let you work comfortably all shift long.


Biodiesel Capability Up to B20¹
Bore 4.1 in
Displacement 268.5 in³
Emissions Meets U.S. EPA Tier 4 Final, EU Stage V, Japan 2014 emission standards.
Engine Model C4.4
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.
