Kubota’s Mid-Size Excavator Legacy
The Kubota KX080-3 is a mid-size compact excavator introduced in the late 2000s as part of Kubota’s push into heavier construction equipment. With an operating weight of approximately 8.4 metric tons and a dig depth of 4.6 meters, it bridges the gap between compact and full-size excavators. Kubota, originally known for agricultural machinery, expanded its construction line with the KX series, which became popular for utility work, site prep, and light demolition. The KX080-3 features a direct-injection diesel engine, load-sensing hydraulics, and a two-pump system for simultaneous operation of boom and travel functions.
What to Expect Around 3,000 Hours
At 3,000 hours, the KX080-3 enters a phase where wear-related issues begin to surface. While many machines reach 6,000 to 8,000 hours with proper maintenance, the 3,000–3,500 hour window often reveals the first signs of component fatigue.
Common service items and wear points include:
To extend the life of a KX080-3 beyond 3,000 hours:
Resale Value and Market Position
A KX080-3 with 3,000 hours typically sells for $40,000 to $45,000 USD, depending on condition and attachments. Machines with documented service history and tight pins command higher prices. The resale market favors Kubota due to its parts availability and dealer network, especially in North America and Southeast Asia.
Conclusion
The Kubota KX080-3 remains a solid investment at 3,000 hours if the machine has been well maintained. Expect to address wear in bushings, hoses, and undercarriage components, but major systems like the engine and hydraulics often remain strong. With proactive service and attention to detail, this excavator can deliver thousands more hours of reliable performance.

Common service items and wear points include:
- Boom and arm bushings: These may develop play, especially if greasing intervals were skipped. Replacing bushings and pins restores precision and prevents further wear.
- Hydraulic hoses: External hoses may show cracking or seepage. Internal hoses, especially those routed through the boom, should be inspected for abrasion.
- Track tensioners and rollers: Undercarriage components begin to wear unevenly. Check for flat spots on rollers and slack in the track chain.
- Swing motor seals: Minor leaks may appear, especially if the machine has been used for frequent rotation tasks.
- Cooling system: Radiator fins and coolant hoses should be cleaned and pressure-tested. Overheating at this stage often stems from clogged fins or degraded coolant.
- Load-Sensing Hydraulics: A system that adjusts flow and pressure based on operator demand, improving fuel efficiency and control.
- Swing Motor: The hydraulic motor that rotates the upper structure of the excavator.
- Track Tensioner: A grease-filled cylinder that maintains proper track tightness.
- Boom Bushing: A wear component between the boom and arm or cylinder, absorbing movement and reducing metal-on-metal contact.
To extend the life of a KX080-3 beyond 3,000 hours:
- Grease all pivot points daily, especially during high-use periods.
- Change hydraulic filters every 500 hours, and fluid every 1,000 hours.
- Inspect air filters monthly, and replace if operating in dusty conditions.
- Flush coolant and replace thermostat every 2 years.
- Monitor engine oil pressure and temperature with a calibrated gauge, not just the dashboard.
