Is the Case CX80 a Good Excavator

[MikePhua]

The CX80 and Its Place in Case’s Lineup
The Case CX80 is a mid-sized compact excavator designed for urban construction, utility work, and tight-access jobsites. Introduced in the early 2000s, it filled a critical gap between mini excavators and full-size machines, offering the reach and power of a larger unit with the maneuverability of a compact frame. With an operating weight around 8.5 tons and a dig depth of approximately 14 feet, the CX80 was engineered to handle trenching, grading, and light demolition with ease.
Case Construction Equipment, a division of CNH Industrial, has been producing earthmoving machinery since 1842. Known for pioneering the integrated backhoe loader in the 1950s, Case has built a reputation for durable, operator-friendly machines. The CX series excavators, including the CX75 and CX80, were part of Case’s push to modernize its hydraulic systems and cab ergonomics while maintaining mechanical simplicity.

Performance and Reliability in the Field
Operators who’ve spent years with the CX75 and CX80 consistently praise their reliability. One unit with over 9,600 hours reportedly never missed a day due to breakdown—a testament to the machine’s build quality and component longevity. The hydraulic system is smooth and responsive, with proportional joystick controls that allow for precise grading and trenching.
Key performance features include:
• Engine: Isuzu 4JJ1X or similar, producing around 55–60 HP
• Hydraulic flow: ~30 GPM with load-sensing valves
• Bucket breakout force: ~11,000 lbf
• Travel speed: up to 2.8 mph
• Swing speed: ~10 rpm
The machine’s balance and stability are particularly noticeable during offset digging or when lifting heavy loads at full reach. Its compact tail swing allows operation in confined spaces without sacrificing lifting capacity.

Rubber Tracks vs Steel Tracks
The CX80 often comes equipped with rubber tracks, ideal for pavement and landscaped surfaces. However, many operators choose to retrofit steel tracks once the rubber wears out. Steel tracks offer better traction in muddy or rocky terrain and are more durable under abrasive conditions.
Considerations when switching to steel:
• Increased ground pressure—may damage finished surfaces
• Slight reduction in travel speed due to added weight
• Higher vibration transmitted to the cab
• Improved durability and lifespan in forestry or demolition work
In regions like Northern England and British Columbia, contractors routinely swap rubber for steel to handle clay soils and steep grades. The conversion is straightforward, provided the undercarriage is in good condition and the sprocket pitch matches the new track type.

Used Market and Availability
Finding a used CX80 can be challenging. In markets like the UK and New Zealand, secondhand units are snapped up quickly due to their reputation for reliability and low operating costs. Machines with under 6,000 hours and clean service records often sell within days of listing.
Tips for buying used:
• Inspect swing bearing for play or noise
• Check hydraulic pump pressure and cycle times
• Look for wear on boom and stick bushings
• Review service history—especially filter and fluid intervals
• Test travel motors for smooth acceleration and deceleration
In 2022, a contractor in Ontario purchased a CX80 with 7,200 hours for CAD $48,000. After minor repairs to the blade cylinder and a new set of steel tracks, the machine was back in full service within a week.

Operator Comfort and Cab Layout
The cab of the CX80 is designed with long shifts in mind. While not as plush as newer models, it offers:
• Adjustable suspension seat
• Clear sightlines to the blade and bucket
• Intuitive control layout with pilot joysticks
• ROPS and FOPS protection
• Optional air conditioning and radio
Operators appreciate the minimal noise and vibration, especially when compared to older models like the Case 9007B. The cab’s insulation and hydraulic damping contribute to reduced fatigue and better focus during precision work.

Maintenance and Long-Term Ownership
The CX80 is known for its low maintenance demands. With proper care, these machines routinely exceed 10,000 hours without major component failure. Key maintenance practices include:
• Hydraulic filter replacement every 500 hours
• Engine oil and coolant checks weekly
• Track tension inspection monthly
• Greasing pivot points daily during active use
• Monitoring fuel injector performance annually
In colder climates, pre-heaters and synthetic hydraulic fluids help maintain performance during winter starts. A contractor in Finland reported improved cycle times after switching to low-viscosity fluid and installing a block heater.

Conclusion
The Case CX80 remains a sought-after excavator for contractors who value reliability, versatility, and ease of maintenance. Whether trenching in tight urban lots or anchoring steel tracks into hillside clay, the CX80 delivers consistent performance with minimal fuss. Its reputation is built not on flashy features but on years of dependable service—making it a quiet workhorse in a noisy industry. For those lucky enough to find one in good condition, it’s a machine that earns its keep day after day.
