374 Hydraulic Excavator

374 Hydraulic Excavator

If you want high production and more durability with less maintenance, the 374 is a terrific choice. With 10 percent more swing torque than the 374F it replaces, you’ll experience faster cycle times. Plus you get two times more structural durability and up to 20 percent less maintenance for longer service life and greater uptime.
