Cat® 374 Hydraulic Excavator

Overview

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.

Key Features

More Comfort. More Performance. More Versatility.

Smooth Operating Performance

The dedicated hydrostatic swing circuit regenerates swing break energy and independently manages cylinder oil flow for proven operating performance.

Track Production from a Single Shift up to 30 Days

Onboard Cat Payload weighs loads on the go to help meet cycle targets and helps prevent overloading or underloading trucks.

Ultimate Operator Comfort

Both cab options - Deluxe and Premium - are equipped with adjustable and optimally shaped seats for healthy support, automatic climate control, USB charging ports, Bluetooth® technology, and plenty of in-cab storage.*

* Not all features are available in all regions. Please check with your local Cat® dealer for availability.

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) and are compatible* with ULSD blended with the following lower-carbon intensity fuels up to: 20% biodiesel FAME (fatty acid methyl ester)* 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. While Caterpillar engines are compatible with these alternative fuels, some regions may not allow their use. * Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels. *** Engines with no aftertreatment devices are compatible with higher blends, up to 100% biodiesel (for use of blends higher than 20% biodiesel, consult your Cat dealer).

Air Conditioning	The air conditioning system on this machine contains the fluorinated greenhouse gas refrigerant R134a or R1234yf. See the label or instruction manual for identification of the gas. If equipped with R134a (Global Warming Potential = 1573), the system contains 1.1 kg (2.4 lb) of refrigerant, which has a CO2 equivalent of 1.573 metric tonnes (1.734 tons). If equipped with R1234yf (Global Warming Potential = 0.501), the system contains 0.93 kg (2.05 lb) of refrigerant which has a CO2 equivalent of 0.001 metric tonnes (0.001 tons).
