BENEFITS & FEATURES
High Performance with Lower Fuel Consumption


  • Use up to 20% less fuel than the 320F excavators.
  • Match the excavator to the job using power modes including new Smart Mode that automatically matches engine and hydraulic power to digging 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 U.S. EPA Tier 4 Final and EU Stage IV emissions standards using a transparent aftertreatment system that requires no operator input or downtime.
  • Auxiliary hydraulic options give you the versatility to use a wide range of Cat attachments.
  • Don't let the temperature stop you from working. The excavator has a standard high-ambient temperature capability of 125 º F (52º C) and cold start capability of 0º F (-18º C). An optional -25º F (-32º C) cold start package is available .
  • Work up to 9,480 feet (3000 meters) above sea level without de-rating.
  • Track your performance through standard Product Link that provides location, machine hours, fuel usage, productivity, idle time, diagnostic codes and other machine data on demand through VisionLink ® online interface.
