A Compact Machine for Big Learning Curves
The Komatsu PC10-6 is a compact hydraulic excavator designed for small-scale earthmoving, trenching, and landscaping. With an operating weight of approximately 2,200–2,500 kg and a dig depth of around 2.5 meters, it’s ideal for residential and light commercial work. Introduced in the late 1980s and early 1990s, the PC10-6 was part of Komatsu’s push into the mini-excavator market, competing with models from Kubota, Yanmar, and Hitachi.
Komatsu, founded in Japan in 1921, has long been a global leader in construction equipment. The PC10 series helped establish its reputation in the compact segment, especially in Asia and North America. Though no longer in production, the PC10-6 remains popular among hobbyists, small contractors, and rural landowners due to its simplicity and affordability.
Starting and Operating Basics
For new owners unfamiliar with excavators, the PC10-6 offers a relatively gentle learning curve. However, basic operational knowledge is essential:
Transporting the Machine
Moving a PC10-6 requires a trailer rated for at least 3 tons and a tow vehicle with sufficient braking capacity. Secure the machine using:
Maintenance and Troubleshooting Tips
Older PC10-6 units may suffer from:
Learning by Doing
For those new to excavation, the PC10-6 is a forgiving platform. Its mechanical simplicity allows for hands-on learning without the complexity of modern electronics. Many rural users have taught themselves to operate and maintain the machine through trial, error, and community advice.
A farmer in Arizona shared that he bought a PC10-6 without knowing how to start it, but within weeks was trenching irrigation lines and clearing brush. His advice: “Don’t be afraid to get dirty. These machines were built to teach you.”
Conclusion
The Komatsu PC10-6 is more than just a mini excavator—it’s a gateway into the world of earthmoving. With basic mechanical knowledge, patience, and a willingness to learn, even complete beginners can master its operation and keep it running for years. Whether you're digging fence posts or reshaping a garden, the PC10-6 offers a compact, capable, and character-building experience.

Starting and Operating Basics
For new owners unfamiliar with excavators, the PC10-6 offers a relatively gentle learning curve. However, basic operational knowledge is essential:
- Starting procedure: Ensure the safety lever is engaged, throttle is set to low, and the fuel shutoff is open. Turn the key and wait for glow plug activation if equipped. Crank the engine and allow it to idle for 2–3 minutes before engaging hydraulics.
- Control layout: The machine uses standard two-stick controls for boom, arm, and bucket. Foot pedals may control track movement or swing depending on configuration.
- Travel and steering: Use track levers or pedals to move forward and backward. Steering is achieved by differential track speed.
Transporting the Machine
Moving a PC10-6 requires a trailer rated for at least 3 tons and a tow vehicle with sufficient braking capacity. Secure the machine using:
- Four-point chain tie-downs on the track frame
- Boom and bucket restraint to prevent movement
- Swing lock pin engaged to prevent upper structure rotation
Maintenance and Troubleshooting Tips
Older PC10-6 units may suffer from:
- Hydraulic leaks at cylinder seals and hose fittings
- Fuel system issues due to sediment or algae in diesel tanks
- Electrical faults in starter circuits or glow plug relays
- Track tension problems from worn idlers or leaking grease cylinders
- Changing engine oil every 100 hours
- Replacing hydraulic filters every 250 hours
- Inspecting track tension monthly
- Greasing pivot points weekly
