Product Description

No matter how hard the work, the Cat® 374 Excavator is built to do it. Three modes of operation, Power, Smart, and Eco, help operators reduce fuel consumption and optimize performance. Built for durability, the 374 is structurally sound with reinforced track rollers, booms, sticks, upper and lower frames. Simple, easy-to-use onboard technology such as Cat Payload, Cat Grade with 2D, Lift Assist, 2D E-Fence, and Work Tool Recognition helps boost efficiency and jobsite safety. The deluxe and standard cab options feature operator-pleasing ergonomic amenities such as the front-facing control panel, keyless pushbutton start, and large touchscreen monitor with jog dial keys.

Note (1)
Net power advertised is the power available at the flywheel when the engine is equipped with fan, air intake system, exhaust system, and alternator with engine speed at 1,700 rpm. Advertised power is tested per the specified standard in effect at 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.
