Caterpillar for Sale: Prices, Specs & Used Market Guide 2026

Caterpillar is the benchmark brand in used construction equipment — the machines hold their value, parts and service are available almost everywhere, and a well-kept CAT will work for years. If you are shopping for a used Caterpillar, this guide covers what is realistically on the market right now, how the pricing works, and what to check before you commit.

What Caterpillar machinery is available

The Caterpillar equipment listed on AGGZ today is led by the company's tracked excavator line, with some road-building machines alongside it:

• Mid-size tracked excavators — the popular CAT 320 and 320GC, plus the 323GC, covering general earthmoving, trenching and site work.
• Large tracked excavators — the 390FL for heavy digging and bulk excavation.
• Road recycling & compaction — a CAT RM350B road recycler for in-place pavement reclamation and a CB-434C tandem roller for asphalt finishing.

The excavators dominate because the 320-class is one of the most in-demand used machines in the world — a sensible first CAT for most contractors, and easy to resell later.

Used prices: what to expect

Across the current Caterpillar listings on AGGZ, priced machines run from roughly US$24,500 for an older tandem roller up to about US$80,000 for a road recycler, with the 320-series excavators sitting in the US$45,000–US$58,000 range. A couple of the newest machines are listed as price on request rather than a fixed figure, which is normal for low-hour, late-model units. Build years span from the early 2000s to 2023, and engine hours run from as little as ~360 on the newest excavator to well over 10,000 on the hardest-worked machines.

What moves the price:

• Model and size class — a 20-tonne 320GC and a large 390FL are different machines for different jobs; match the class to the work before comparing prices.
• Year and engine hours — a 2023 excavator with a few hundred hours sits well above a 2019 machine with 10,000+ hours, even in the same model family.
• Configuration and attachments — undercarriage condition, quick-coupler and buckets all affect the figure.

What to check before you buy a used Caterpillar

CAT machines are built to last, but a used unit still deserves a careful inspection:

• Hours and service history — confirm the displayed hours and ask for records; CAT dealers log service against the serial number, so a genuine history is usually traceable.
• Undercarriage (excavators) — tracks, rollers, idlers and sprockets are among the most expensive wear items; budget for them if they are near the end of life.
• Hydraulics and structure — check for leaks, test the boom, arm and swing through full range, and inspect the boom/stick and pins for cracks or heavy repair.
• Engine and emissions — a clean cold start and no warning codes; confirm the machine meets the emissions rules of your destination country before importing.
• Documentation and export readiness — confirm the seller can supply the paperwork you need to register or import.

Where you cannot inspect in person, ask for detailed photos, a cold-start and running video, and where possible an independent inspection before sending payment.
