Kubota KX080-5 vs CAT 308 CR

In this episode of the compact excavator showdown, we’re comparing the Kubota KX080-5 vs CAT 308 CR! These two industry leaders offer impressive digging power, operator comfort, and advanced features to worksites, but which one best fits your workload? At Glenn B. Dorning, Inc., we’re breaking down each machine's specs, performance, and usability so you can make the most informed decision possible!

Engine Power & Hydraulic Performance

The CAT 308 CR has a CAT C3.3B engine producing up to 74.3 gross horsepower and 70.3 net horsepower, giving it strong muscle for larger-scale excavation or heavy lifting tasks. The 308 CR features a load-sensing hydraulic system with impressive digging forces and a flow rate of up to 167 liters per minute, giving excellent responsive power for applications.

In comparison, the Kubota KX080-5 has a V3307 engine that produces 66.6 gross horsepower and 62.3 net horsepower. It’s slightly less than the 308 CR, but still plenty for utility work, trenching, grading, and site preparation. Its two-pump load-sensing hydraulic system sets Kubota apart, and it is designed for smooth, simultaneous operation of attachments and travel functions. For precision work, the KX080-5 offers exceptional control.

Digging Depth, Reach, & Size

Both machines provide solid reach and digging depth, but the CAT 308 CR is slightly ahead. With a maximum digging depth of over 15 feet and a reach at ground level of just over 24 feet, this excavator is great for deeper utility installs or large trenching jobs. It also offers a long stick option for added reach!

The Kubota KX080-5 offers nearly identical performance with a digging depth of over 15 feet and a max reach of over 23 feet. This compact model is a tight-tail swing excavator with a width of over seven feet, making it easier to maneuver in restricted spaces. If your job takes you into residential areas, city developments, or around structures, Kubota’s smaller footprint may be the better fit.

Operator Comfort & Cab Experience

Comfort matters when you spend long hours in the cab, and both manufacturers have made operator experience a top priority. Kubota’s KX080-5 has a spacious, quiet cab with just 72 dB of noise. The layout is clean and ergonomic, with a double-adjustable air suspension seat and wide foot space. A seven-inch LCD screen gives operators quick access to auxiliary hydraulic settings, maintenance alerts, and performance data. Features like keyless start, LED work lights with delay shut-off, and a rearview camera enhance convenience and safety! Kubota emphasizes ease of use and visibility.

The CAT 308 CR has similar features. Its sealed and pressurized cab features a suspension seat, intuitive wrist rests, and the Stick Steer travel mode, which allows you to control the machine via joystick rather than pedals. The Next Generation monitor provides real-time diagnostics and machine settings, and cruise control makes longer tasks more manageable. CAT delivers more automation and customization for experienced operators.

Technology & Maintenance Features

Kubota has put thought into daily usability and maintenance. The KX080-5 features one-sided engine maintenance, a triple-opening hood, and a two-piece dozer hose design that simplifies replacement on-site! The KX080-5 features an automatic engine shutdown and idle system to reduce wear and save fuel. Telematics via KubotaNOW allows operators and fleet managers to monitor machine data remotely, from hours to fuel usage and error codes.

CAT’s 308 CR also delivers easy servicing, with grouped service points accessible at ground level and large service panels for routine checks. The machine also comes ready with Product Link Elite Lite for telematics, ecology drains, and durable components for long-term reliability. CAT focuses here on uptime and dealer-connected support, an advantage for operations needing quick answers and on-site parts access.

Final Verdict: Which Is the Better Choice?

Choosing between the Kubota KX080-5 and the CAT 308 CR ultimately comes down to your job requirements. If you need maximum horsepower, longer reach, and automation tools like Stick Steer and cruise control, the CAT 308 CR is a wise choice. It's well-suited for larger jobs and experienced operators who prefer in-depth customization.

If you value cab comfort, intuitive controls, compact maneuverability, and easy transporting (not to mention smoother multi-function hydraulic operation), the Kubota KX080-5 is a strong contender. Its design caters to utility contractors, municipalities, and builders working in tight areas who want reliability, reduced maintenance, and a top-tier operator experience.
