Komatsu Mini Excavator Price: What to Expect Across 5 Models

Japan Machinery Trader sources used Komatsu mini excavators directly from Japanese rental fleets and auction channels — machines that typically carry lower hours and more consistent maintenance than what turns up in most open markets. Below are five models worth knowing, what typically drives their price up or down, and what to check before you buy any of them.

What actually moves the price

Three factors do most of the work on any Komatsu mini excavator's price: the model and its operating hours, condition as verified by an actual inspection (not just a listing photo), and the state of the Japanese auction market at the time it's sourced. Rental fleet machines tend to carry lower hours because they rotate on fixed schedules rather than running until something breaks, which keeps wear more predictable than on privately owned units.

Indicative 2026 price ranges

The figures below are for used, export-ready machines in good working condition, sourced from Japan. Operating hours, attachments, and configuration all move the final number, so use these as planning benchmarks rather than fixed prices:

• PC10UU-5 (~1,000 kg) — roughly ¥500,000–¥900,000
• PC20MR-5 (~2,000 kg) — roughly ¥900,000–¥1,500,000
• PC30MR-5 (~3,000 kg) — roughly ¥1,200,000–¥2,000,000
• PC55MR-5 (~5,500 kg) — roughly ¥2,000,000–¥3,500,000

PC10UU-5 — the compact end

Built for tight, access-restricted spaces, the PC10UU-5 is the smallest machine in this lineup at around 1,000 kg. Hours are the single biggest driver of price here: units under 1,000 hours sit toward the top of the range, while machines approaching 2,500 hours pull toward the bottom. Attachment packages like a hydraulic breaker or extra buckets add to the price. It's best suited to indoor demolition, urban landscaping, and narrow trench work, thanks to a short tail-swing radius that keeps it safe on boundary-tight sites. Before buying, check the boom and arm cylinder seals for leaks and the rubber tracks and undercarriage rollers for excessive wear.

PC20MR-5 — a step up in reach

At around 2,000 kg, the PC20MR-5 offers more digging reach and hydraulic output than the PC10UU-5 while staying compact enough for access-restricted sites. Operating hours and undercarriage condition create the largest price gaps between units, and a hydraulic attachment can add a meaningful premium above the base price. It handles utility trenching, light foundation excavation, and grading in tight urban environments, plus load-and-dump work on small residential projects. Check the swing bearing and slew ring for play or grinding during full rotation, along with the boom and arm cylinder seals and pin/bushing clearances.

PC30MR-5 — deeper digging, still compact

The PC30MR-5 (around 3,000 kg) delivers more digging force and reach than the PC20MR-5 for deeper utility work and foundation excavation, while still fitting through standard site gates. Hours and undercarriage wear drive most of the price spread, and a quick coupler or hydraulic attachment adds a real premium. Its zero tail-swing configuration keeps it productive in narrow corridors where full-size machines can't operate. Before buying, inspect the final drives and travel motors for leaks, check the boom cylinder rod surfaces for scoring, and request an inspection report covering the swing bearing and linkage clearances.

PC55MR-5 — the top of the compact class

At roughly 5,500 kg, the PC55MR-5 sits at the top of Komatsu's compact range with digging performance that rivals some full-size machines, while still fitting on access-restricted urban sites. Hours and undercarriage condition again drive most of the price difference, and hydraulic attachment packages or auxiliary lines add a further premium. It suits deep trench work, large utility excavation, and heavy site prep, plus bulk material handling where cycle speed matters. Check the final drives and travel motors for leaks or unusual noise, examine the boom cylinder rod surfaces closely, and get a full inspection report covering the swing bearing and boom/arm linkage.

What an export-ready quote should include

A real quote covers more than the machine price. It should include a full inspection report, export documentation, customs paperwork, and shipping coordination to your destination port — so you're not separately hunting down a freight forwarder or navigating Japanese export rules on your own. Ask for that breakdown before you commit, and treat any number quoted without an inspection report behind it with caution.
