Cat leads used financed compact excavator sales at roughly 24.3% — the largest share in the category.
That means plenty of supply, and it means Cat machines carry a price premium used as well as new. Both are worth understanding before you buy.
What a Used Cat Brings
The largest used supply in the category. More machines available means more choice and more competition among sellers — you can afford to walk away from a bad one.
Global dealer network. Cat's dealer infrastructure is extensive, and parts availability is excellent essentially everywhere.
Strong resale. Cat holds value well, which is part of why the used premium exists.
Build reputation. Cat's compact line is well regarded.
Attachments frequently included — thumbs, buckets, couplers. Real value that gets undervalued in negotiation.
The Premium Cuts Both Ways
Worth stating plainly.
Cat machines cost more used, not just new. The brand premium follows the machine into the secondary market.
That means a used Cat and a used machine from a smaller brand at the same price aren't the same age or hours — you're typically getting an older or higher-hour Cat for the money.
Whether that's a good trade depends on what you value. The dealer network and resale strength are real. Whether they're worth more than fewer hours on a comparable machine is a judgment call.
What a New Machine Brings
Warranty. Coverage for what you can't inspect.
Known history.
Zero hours on the undercarriage — the most expensive wear system.
Configuration choice, including auxiliary hydraulics, which cost substantially more to add later.
Better financing terms.
The Undercarriage Rule
Price a full undercarriage replacement and add it to the used machine's purchase price before comparing.
On a higher-hour machine — which is what a Cat premium frequently gets you at a given price — this matters more, not less.
That single adjustment decides this comparison more often than the brand does.
What Else to Check
Slew bearing — play or noise means a major repair.
Pins and bushings — slop indicates front-end wear.
Hydraulic cylinders — scored rods, leaks, drift under load.
Did it run a hammer? The hardest hours a machine takes. Ask directly; look for cracks and repairs at boom and arm.
Attachment fitment. Cat uses its own pin dimensions and coupler standards. Verify against anything you already own — there's no universal excavator standard.
Service records — more predictive than hours.
Auxiliary hydraulics — present, and which circuits?
How to Decide
Buy the used Cat if:
- The undercarriage checks out or the price reflects it
- You value the dealer network
- Resale strength matters to your plans
- You can inspect competently
- The hours are reasonable for the price
Buy new if:
- You need a specific configuration
- Warranty matters to your cash flow
- You'd rather have zero hours than a badge
- You run machines to end of life
- You can't evaluate used equipment confidently
The Honest Summary
A used Cat is a good machine with real support behind it. The dealer network and parts availability are genuine advantages, and the used supply means you have options.
The premium is also real. At any given price you're typically getting more hours on a Cat than on a comparable machine from a smaller brand.
Run the undercarriage math, count the hours honestly, and decide whether the network and resale are worth what they cost you in machine condition.
FAQ
Why do used Cats cost more?
Brand strength, dealer network, and resale demand. It's a real premium and it reflects real things.
Is the premium worth it?
If you value dealer support and resale, yes. If you run machines to end of life and can service them yourself, less so.
