  • Use up to 10 percent less fuel than the 330D2 Excavator in similar applications.
  • Increase operating efficiency up to 45 percent with standard Cat technologies that lower operator fatigue and your operating costs, including fuel consumption and daily maintenance.
  • The C7.1 engine can run on biodiesel up to B20 and meets U.S. EPA Tier 3/EU Stage IIIA/China Nonroad Stage III/Brazil Mar-1 equivalent emission standards.
  • Match the excavator to the job with power modes; let Smart mode automatically match engine and hydraulic power to digging conditions.
  • 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 52° C (125° F) and cold start capability of –18° C (0° F). An optional –32° C (–25° F) cold start package is available.


  • Work up to 3000 m (9,840 ft) above sea level without de-rating.
  • Don’t let the temperature stop you from working. The excavator has a standard high-ambient temperature capability of 52° C (125° F) and cold start capability of –18° C (0° F). An optional
     - 32° C (–25° F) cold start package is available.
  • Auto warm up speeds up hydraulic oil warming in cold temperatures and helps prolong the life of components.
  • Two levels of fuel filtration protect the engine from dirty diesel fuel.
  • Grease sealed between track pins and bushings reduces travel noise and prevents debris from entering to increase undercarriage life.
  • The track guiding guard helps keep the excavator track aligned when traveling and working on slopes.
  • The sloped track frame prevents mud and debris accumulation, helping reduce risk of track damage.


  • The cab has a wide seat that adjusts for operators of all sizes.
  • Control the excavator comfortably with easy-to-reach controls all located in front of you.
  • Standard automatic climate control keeps you at the right temperature all shift long.
  • Advanced viscous mounts reduce cab vibration by up to 50 percent over previous excavator models.
  • Stow your gear with plenty of in-cab storage beneath and behind the seat, overhead, and in the consoles. A cup holder, document holder, bottle holder, and coat hook are also provided.
  • Use the standard radio’s USB ports and Bluetooth® technology to connect to personal devices.


  • Start the engine with a push button; use a Bluetooth key fob, smartphone app, or the unique Operator ID function.
  • Program your power mode and joystick preferences using Operator ID; the excavator will remember what you set each time you go to work.
  • Navigate quickly on the standard high-resolution 203 mm (8 in) 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.
  • Find the tool you need
     - even if it’s hidden beneath overgrowth or debris. The available Bluetooth reader can search for any work tool equipped with Cat asset tracking devices up to a range of 60 m (200 ft).


  • Expect up to 20 percent less maintenance cost than the 330D2 (savings calculated over 12,000 machine hours).
  • Do all daily maintenance at ground level.
  • Check engine oil level quickly and safely with the new ground-level engine oil dipstick; fill and check engine oil on top of the machine with a conveniently located second dipstick.
  • Track your excavator’s filter life and maintenance intervals via the in-cab monitor.
  • Change all fuel filters at a synchronized 1,000 hours
     - a 100 percent increase over the 330D2 fuel filters.
  • Expect the new air intake filter with pre-cleaner to last up to 1,000 hours
     - a 100 percent increase over the previous filter.
  • 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 3,000-hour replacement interval
     - 50 percent longer than previous filter designs.
  • High-efficiency cooling fans run only when needed; you can program intervals so they automatically reverse to keep cores clean without interrupting your work.
  • S·O·S ports are on ground level, simplifying maintenance and allowing for quick, easy extraction of fluid samples for analysis.


  • Access 100 percent of daily maintenance points from ground level
     - no need for you to climb on top of the excavator.
  • Keep your excavator secure with Operator ID. Use your PIN code on the monitor 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 pillars, larger windows, and a flat engine hood design. A rearview camera is standard, and a right-side-view camera is available.
  • New right service platform design provides easy, safe, and quick access to upper service platform; the service platform steps use anti-skid punch plate to prevent slipping.
  • The standard hydraulic lockout lever isolates all hydraulic and travel functions in the lowered position.
  • Ground-level shut-off switch stops all fuel to the engine when activated and shuts down the machine.
