Benefits and Features
- Use up to 25% less fuel than the 320F excavator.
- Increase operator efficiency by up to 45% with a suite of Cat technologies that lower operator fatigue and your operating costs, including fuel consumption and daily maintenance.
- Match the excavator to the job using power modes including new Smart mode that automatically matches engine and hydraulic power to your digging conditions.
- The advanced hydraulic system provides the optimum balance of power and efficiency while giving you the control you need for your precise digging requirements.
- The electronically controlled, twin-turbocharged engine meets U.S. EPA Tier 4 Final and EU Stage IV emission standards using a transparent after treatment system that requires no operator input or downtime.
- Auxiliary hydraulic options give you the versatility to use a wide range of Cat attachments.
- Advansys™ bucket tips increase penetration and improve cycle times. Tip changes can be done quickly with a simple lug wrench instead of a hammer or special tool, improving safety and uptime.
- Don't let the temperature stop you from working. The excavator has a standard high ambient temperature capability of 52º C (125º F) and cold start capability of -18º C (0º F). An optional -32º C (-25º F) cold start package is available.
- Automatically stop excavator swing at operator-defined set points in truck loading and trenching applications with Swing Assist, which will help you use less effort and consume less fuel.
- Keep your tracks on the ground in lifting and hard digging with Boom Assist.
- Set your desired bucket angle and let Bucket Assist automatically maintain the angle in sloping, leveling, fine grading, and trenching applications for easy, accurate, and fast jobs.

- Improved viscous mounts reduce cab vibration by up to 50% over our previous excavator models.
- Stow your gear with plenty of in-cab storage behind the seat, overhead, and in the consoles.
- The standard radio has USB ports and Bluetooth® technology enabled to connect your device and make hands-free calls.
- Protect hydraulic components in cold weather. The auto warm-up feature speeds hydraulic oil warming in cooler temperatures.
- The fuel system is protected from contamination of fuel by three levels of filtration.
- Bottom guarding protects engine and hydraulic components from damage while swinging and traveling.
- The hydraulic tank with a new oval shape designed to improve stress resistance.
- The strong X-structure lower frame carries loads from the excavator's upper structure to the track.
- Travel motor hydraulic lines are routed inside of the frame to protect them 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 rebuild-able 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.
- Start the engine with a push button; use a Bluetooth key fob, or the Operator ID passcode.
- Program each joystick button, including response and pattern, using Operator ID; the machine will remember what you set each time you go to work.
- Program up to four depth and slope offsets so you can easily get to grade without a grade checker – a real time saver and safety enhancer on the jobsite.
- Save more time and energy with available work tool recognition. A simple shake of the attached tool confirms its identity; it also ensures all the attachment settings are correct so you can get to work quickly and efficiently.
- Navigate quickly on the standard high-resolution 203 mm (8 in) touchscreen monitor, or with the optional 254 mm (10 in) touchscreen monitor, or with the aid of the jog dial control.
- Protect your hammer from overworking. Auto hammer stop warns you after 15 seconds of continuous firing and then automatically shuts it off after 30 seconds -- all to prevent wear and tear on the attachment and excavator.
- A second 254 mm (10 in) monitor is available for the advanced grade 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.
- The Cat PL161 attachment locator is a Bluetooth device that makes finding your attachments and other gear quick and easy. The excavator's onboard Bluetooth reader or Cat App on your phone will locate the device automatically.
- Save more time and energy with the available work tool recognition feature. A simple shake of the attached tool confirms its identity; it also ensures all the attachment settings are correct so you can get to work quickly and efficiently.
- Auto Dig Boost increases power by up to 8% for better bucket penetration, shorter cycle times, and greater payloads.
- Make moving the excavator much easier with Cat Stick Steer. Simply push a button and use one hand to travel and turn instead of both hands or feet on levers or pedals.
- Need more lift during your shift? Turn on Auto Heavy Lift and get 8% more power exactly when you need it for as long as you need it.
- Extended maintenance intervals reduce maintenance costs by 20percent over the Cat 320F excavator (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.
- Reversing electric cooling fans make it easy to clean radiator, oil coolers, and condensers.
- The new air intake filter with precleaner has double the dust holding capacity of the previous air intake filter.
- Using Cat genuine oil and filters and doing your typical S∙O∙S monitoring will double the current service interval to 1,000 hours, giving you greater uptime to do more work.
- 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.
- S·O·S ports are on ground level, simplifying maintenance and allowing for quick, easy extraction of samples for fluid analysis.
- Work safely under structures or near traffic with standard 2D E-fence integrated right out of the factory. It prevents any part of the excavator from moving outside operator-defined set points, avoiding hazards and jobsite accidents.
- Lift Assist helps you avoid tipping. With visual and auditory alerts, you’ll know if your load is within the excavator’s safe working range limits.
- Access 100 percent of daily maintenance points from ground level – no need for you to climb on top of excavator.
- 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.
- The standard hydraulic lockout lever isolates all hydraulic and travel functions in the lowered position.
- Ground-level shutoff switch stops all fuel to the engine when activated and shuts down the machine.
- Rear and right-hand-sideview cameras are standard.Upgrade to 360° visibility and see under the excavator, allowing the operator to easily visualize objects and personnel around the excavator in a single view.
- Right-hand 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 handrails comply with ISO 2867 requirements.
- Enhance operator safety by adding Cat Command to your fleet. The remote control system keeps you away from potential hazards. The new non-line-of-site kit comes with Wi-Fi radio, cameras, and microphone to allow you to work anywhere you want.
- 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.
- Cat Detect - People Detection helps protect the most valuable asset on any jobsite – people. The system uses smart cameras with depth sensors to provide the operator with visual and auditory alerts so he or she can take immediate action when a person is too close to the excavator.
