Overview

Incredible Power, Durability and Versatility.

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.

Benefits

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.
