The Cat® 320 excavator brings premium performance with simple-to-use technologies like Cat GRADE with 2D, Grade Assist, and Payload - all standard equipment from the factory to boost your operator efficiencies up to 45%. Combine these features with a new cab, longer maintenance intervals that lower your maintenance costs up to 15%, and a power system that reduces fuel consumption by up to 25% and you have a low-cost-per-unit-of-production excavator that's perfect for medium- to heavy-duty applications.
Increase operator efficiency by up to 45% with a suite of Cat Connect technologies that lower operator fatigue and your operating costs, including fuel consumption and daily maintenance.
The C4.4 ACERT™ engine can run on biodiesel up to B20 and meets U.S. EPA Tier 4 Final and EU Stage IV emission standards with an aftertreatment system that requires no maintenance or downtime.
The advanced hydraulic system provides the optimum balance of power and efficiency while giving you the control you need for your precise digging requirements.
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.
Available SmartBoom™ lets the boom freely travel up and down without using any pump flow so operators can focus on stick and bucket work. The benefits are reduced operator stress and reduced fuel consumption.
Don’t let the temperature stop you from working. The excavator has a standard ambient temperature capability of 46° C (115° F) and optional high-ambient capability of 52° C (125° F). Standard cold start capability is –32° C (–25° F).
Boost Efficiency and Boost Productivity with Integrated Cat Connect
Boost productivity up to 45% versus traditional grading with the standard Cat GRADE with 2D system — includes indicate-only and laser capability.
Dig with real-time guidance on depth, slope, and horizontal distance to grade.
The 2D system is upgradable to Cat GRADE with Advanced 2D or Cat GRADE with 3D.
Standard Grade Assist:
Stay on grade – simply and effortlessly – with single-lever digging.
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.
Keep the tracks on ground in lifting and hard digging with Boom Assist.
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.
Standard Cat PAYLOAD on-board weighing system:
Achieve precise load targets and increase loading efficiency with on-the-go weighing and real-time estimates of your payload without swinging.
Track your daily productivity such as truck target weights and load/cycle counts.
Calibration can be performed in a matter of minutes.
Combine Payload with VisionLink® and remotely manage your production targets.
Upgrade to optional Cat GRADE with Advanced 2D:
Create and edit grade designs with ease on a second high-resolution 10 in (254 mm) touchscreen monitor.
Upgrade to optional Cat GRADE with 3D:
Create and edit designs with ease and see the front linkage's full range of motion on a second high-resolution 10 in (254 mm) touchscreen monitor.
Know the excavator's exact position relative to GPS and GLONASS systems.
The machine automatically compensates for excavator pitch and roll caused by sloping ground conditions.
Standard Product Link™ provides location, machine hours, fuel usage, productivity, idle time, diagnostic codes, and other machine data on demand through VisionLink® online interface, helping you improve jobsite efficiency with lower operating costs.
Work in Comfort in the All-New Cab
Choose between Comfort and Deluxe cabs – both with automatic climate control.
Sit in wide seats that adjust for all size operators; stay warm with the Deluxe heated seat.
Enjoy wide spacing between consoles for a more comfortable environment.
Get in and out of the cab easier using the tip-up left console (Deluxe cab only).
Advanced viscous mounts reduce cab vibration up to 50 percent over previous excavator models.
Control the excavator comfortably with easy-to-reach controls all located in front of you.
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 personal devices and make hands-free calls.
Simple to Operate
Start the engine with a push button; use a Bluetooth key fob, smartphone app, or the unique Operator ID function.
Program each joystick button, including response and pattern, using Operator ID; it will also remember climate control fan and radio settings.
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.
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.
Expect up to 15 percent less maintenance cost than the 320F. (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.
Do no required maintenance on the Cat Clean Emissions Module.
Change all fuel filters at a synchronized 500 hours.
Expect the new air intake filter with precleaner to last up to 1,000hours – 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 – 50percent longer than previous filter designs.
The new high-efficiency electric cooling fans only run when needed and reverse to keep cores free from debris.
S·O·Sports simplify maintenance and allow for quick, easy extraction of fluid samples for analysis.
Work safely under structures or near traffic with the standard 2D E-fence feature integrated right out of the factory, which prevents any part of the excavator from moving outside operator-defined set points, avoiding hazards and jobsite accidents.
Access 100% 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.

Ground level shut-off switch stops all fuel to the engine when activated and shuts down the machine.
A rearview camera is standard and upgradable to an optional 360° visibility camera for visibility all around the excavator, allowing the operator to easily visualize objects and personnel around the excavator in a single view.
New 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.
Available boom and stick lowering check valves prevent reverse flow, keeping your front linkage securely in place should the hydraulic system unexpectedly lose power.
The handrails comply with ISO 2867:2011 requirements.
The lower frame meets ISO 15818:2017 lifting and tie-down requirements.
