  • Use up to 12% less fuel than the 330D2 Excavator in similar applications.

  • The C7.1 Brazil MAR-1 emission standards, equivalent to U.S. EPA Tier 3 and EU Stage IIIA.

  • 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% 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,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.

  • Protect your hammer tool from overheating and rapid wear. Auto hammer stop warns you after 15 seconds of continuous firing and then automatically shuts it off after 30 seconds - all to extend the tool’s service life.

  • 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.

  • The Cat PL161 Attachment Locator is a Bluetooth device that makes finding your attachments and other gear quick and easy. 

  • 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 25% 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 latest 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.

  • Expect the latest air intake filter with pre-cleaner to last up to 1,000 hours – a 100% increase over the previous filter.

  • The latest 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% 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.

  • Boost productivity with proactive service reminders. Our integrated vehicle health management system alerts the operator with step-by-step service guidance, along with parts needed, so you don't experience any unnecessary downtime.

  • S·O·SSM ports simplify maintenance and allow for quick, easy extraction of fluid samples for analysis.



  • Access 100% 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.

  • The latest 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.

  • Enhance jobsite safety. Add a swing alarm to alert people when you're rotating from trench to stockpile and back again.

  • Make service work easier and safer with optional inspection lighting. With the flip of a switch, lights will illuminate the engine, pump, battery, and radiator compartments to enhance visibility.
