High Performance with Lower Fuel Consumption

  • Use up to 20% less fuel than the 320D2 GC excavator.
  • Match the excavator to the job using power modes; let Smart mode automatically match engine and hydraulic power to working conditions.
  • The advanced hydraulic system provides the optimum balance of power and efficiency while giving you the control you need for precise digging requirements.
  • Your joystick commands adjust pump flow based on valve priority putting hydraulic pressure and flow where it needs to go, giving you improved fast light- to medium-load cycle times.
  • The electronically controlled, turbocharged engine meets Tier 3/Stage IIIA equivalent emission standards.
  • Auxiliary hydraulic options give you the versatility to use a range of Cat attachments.
  • Don't let the temperature stop you from working. The excavator has a standard high-ambient temperature capability of (52º C) 125º F and -32º C (-25º F) cold start package.
  • Work up to 9,480 feet (3000 m) above sea level without de-rating.
