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.

Work in Comfort in the All-New Cab

  • Sit in new, wide seats that adjust for operators of all sizes.
  • Enjoy wide spacing between consoles for a more comfortable environment.
  • Control the excavator comfortably with easy-to-reach controls all located in front of you.

  • The standard radio has USB ports and Bluetooth® technology enabled to connect your device and make hands-free calls.

Built for Long Life

  • Protect hydraulic components in cold weather. The auto warm-up feature speeds hydraulic oil warming in cold temperatures.
  • The fuel system is protected from dirty fuel by three levels of filtration.
  • Bottom guarding protects engine and hydraulic components from damage while swinging and traveling.
  • The hydraulic tank uses a new oval shape to improve stress resistance.
  • The strong X-structure lower frame carries the loads from the machine upper structure to the track.
  • Travel motor hydraulic lines are routed inside of the frame to protect from damage.
  • The sloped track frame design prevents mud and debris from accumulating and damaging tracks.
  • The grease lubricated tracks have grease sealed between the pin and bushing to prevent debris from entering and reducing life.
  • The track rollers are rebuildable and sealed to prevent dirt and debris causing wear of internal components.
  • A bolt-on track guiding guard helps maintain track alignment while traveling or working on slopes.

Simple to Operate

  • Start the engine with a push button.
  • Program each joystick button, including response and pattern, using Operator ID; it will also will remember climate control fan and radio settings.
  • You can navigate quickly on the standard high-resolution 8 in (203 mm) touchscreen monitor or with the aid of the jog dial control.
  • Not sure how a function works or how to maintain the excavator? Always have the operator’s manual at your fingertips in the touchscreen monitor.


  • Extended maintenance intervals reduce maintenance costs by 15% over the Cat 320F excavator. (15% savings calculated over 12000 machine hours.)
  • Reversing electric cooling fans make it easy to clean radiator, oil coolers, and condensers.
  • An all-new engine air cleaner with integrated pre-cleaner has twice the life of radial seal air cleaners.
  • The new hydraulic oil filter provides improved filtration performance, anti-drain valves to keep oil clean when the filter is replaced, and longer life with a 3000 hour replacement interval – 50% longer than previous filter designs.
  • Track your excavator’s filter life and maintenance intervals can via the in-cab monitor.
  • Check engine oil level quickly and safely with the new engine oil dip stick located on ground level.
  • S·O·S ports with extended sampling intervals are on ground level, simplifying maintenance and allows for quick easy extraction of samples for fluid analysis.


  • Access 100% of daily maintenance points from ground level – no need for you to climb on top of excavator.
  • Keep your excavator secure. Use your PIN code on the monitor, the Bluetooth key fob, or your smartphone to enable the pushbutton starting feature.
  • The standard ROPS cab meets ISO 12117-2 2008 requirements.
  • Enjoy great visibility into the trench, in each swing direction and behind you with the help of smaller cab posts and larger windows.
  • A rearview camera is standard for improved visibility behind the cab.
  • New right-hand service platform access provides easy, safe, and quick access to upper service platform and the service platform steps use recessed bolts and anti-skid punch plate to prevent slipping. The handrails comply with ISO2867 requirements.
