Used Komatsu PC20-6 excavator
A mini under 6t Komatsu machine for export from China. Price follows the exact unit, not the model name.

Komatsu PC20-6 is usually checked by buyers who need a small used Komatsu excavator for light jobs, narrow access and lower transport pressure. The decision between a PC20-6 and a PC20-7 should follow the exact machine’s condition, not the version name. Always compare cold start, hydraulic smoothness, travel power and rubber track condition first.
A used Komatsu PC20-6 can make sense for small construction, farm support, landscaping, trenching, house foundation work, rental fleets and resale markets. It is easier to move and operate in limited spaces than larger Komatsu mini excavators, especially when the job does not require strong digging force or long-hour heavy-duty operation.
The key value of PC20-6 is not fresh paint or a low displayed hour meter. For a small used excavator, the real value is decided by cold start condition, hydraulic smoothness, swing response, rubber track wear, travel motor condition, final drive area, bucket pins, leakage and exact-machine working video.
This machine is not the right choice for heavy digging, rock breaking, large loading, mining work or long daily harsh construction. It is also not a 20-ton Komatsu excavator. Buyers looking for a 20-ton class Komatsu machine should compare PC200, PC210 or PC220 instead. If your job needs stronger digging power, deeper trenching or longer rental use, PC30, PC35MR, PC40 or PC50 may be safer to compare.
PC20-7 may be worth checking when buyers want a newer nearby PC20 version, but it should not automatically be treated as a better machine. A clean PC20-6 with strong travel, smooth hydraulics and good rubber tracks can be more practical than a tired PC20-7. Before comparing PC20-6 and PC20-7, ask for nameplate, engine plate, current working video and undercarriage details.
Before quotation, check the exact machine carefully. Ask for cold start, smoke, idle stability, engine sound, boom lifting, arm pulling, bucket movement, swing, both-side travel, straight travel, rubber tracks, sprocket, rollers, idlers, travel motor area, final drive area, bucket pins and oil leakage. For PC20-6, travel condition and hydraulic smoothness are more important than side stickers.
Current Komatsu PC20-6 stock may change by year, hours, bucket, rubber track condition, repainting level and working condition. Similar PC20-7 or other PC20 machines may be available, so ask for the latest working video before quotation. Price differences usually come from version, engine condition, hydraulic response, travel system, rubber track wear, leakage, bucket wear, repainting and transport preparation.
Final Komatsu PC20-6 specs should be confirmed by the current machine, nameplate and engine plate. PC20 weight, engine, bucket size and transport size may vary by version and configuration.
