Compact loaders are the most-used machines on many job sites, and Caterpillar's lineup is one of the broadest on the market. If you're shopping used, the model numbers are your fastest way to narrow the field — once you know how to read them.
How CAT compact loader numbering works
Two things to decode:
- The number scales with capacity and size. Within the family, a higher number generally means a bigger machine with more rated operating capacity and more hydraulic flow. A 226 is a small-frame machine; a 262 is mid-frame; a 272 is at the large end of the wheeled range.
- Numbers ending in 9 or 5 are usually compact track loaders (CTLs). Models like the 239, 249, 259, 279, 289 and 299 ride on rubber tracks, while the 226 / 232 / 236 / 242 / 246 / 262 / 272 line are wheeled skid steers. This is the single most useful shortcut when scanning listings.
- Suffixes like D3 mark the generation. A 262D3 is a later revision than a 262D. Newer generations generally bring cab, hydraulic and electronics updates.
- XE denotes a high-efficiency drive on select models.
Wheels or tracks? Decide this first
This choice matters more than the model number, and it comes down to your ground conditions.
Wheeled skid steers
Lower purchase price, lower running cost, and far cheaper to re-shoe — tires versus rubber tracks is not a close comparison on cost. They're faster on hard surfaces and ideal for paved yards, demolition on slab, snow work and general utility duty. The downside is ground pressure: on soft, wet or sandy ground they'll rut and get stuck where a CTL keeps working.
Compact track loaders
Dramatically better flotation, traction and grading stability. If you work on dirt, mud, sand or turf — landscaping, site prep, grading — a CTL will simply do more days of work per year. You pay for it: higher purchase price, higher resale price, and rubber tracks and undercarriage components that are a real recurring cost. Track wear is the number one thing to inspect on a used CTL.
Choosing a size class
Small frame (roughly the 226 / 232 / 239 range)
Light, nimble, easy to trailer behind a pickup, and able to fit through standard gates. Best for landscaping, light utility, interior work and tight residential sites. Limited lift capacity and hydraulic flow, so demanding attachments are off the table.
Mid frame (roughly the 236 / 242 / 246 / 249 / 259 range)
The volume sellers, and for good reason. Enough capacity and hydraulic flow for the majority of attachments, still transportable without a heavy trailer, and the deepest used market of the three tiers. If you're buying one machine to do most things, start here.
Large frame (roughly the 262 / 272 / 279 / 289 / 299 range)
Serious lift capacity and high-flow hydraulics for demanding attachments — mulchers, cold planers, large mixers, big brush cutters. These are production machines. They cost more to buy and transport, but if you're running high-flow attachments regularly, an undersized machine will cost you far more in lost time.
Match the machine to the attachment, not the other way round
The most common and most expensive sizing mistake is buying the loader first and discovering later that it can't drive the attachment you need. Check two numbers before you commit:
- Rated operating capacity (ROC) — determines what you can safely lift and carry.
- Auxiliary hydraulic flow (standard vs. high flow) — determines which attachments will actually run at full performance. High-flow attachments on a standard-flow machine will underperform or overheat.
Inspecting a used CAT compact loader
Beyond the general 10-point inspection, focus on these:
- Tracks and undercarriage on a CTL. Measure remaining track life and inspect rollers, idlers and sprockets. This is the biggest hidden cost on a used CTL by a wide margin.
- Loader arm pins and bushings. Work the arms and watch for slop — these machines cycle constantly and joints wear.
- The auxiliary hydraulic couplers. Leaks and damaged quick-connects here are common and point to hard attachment use.
- Cab, controls and safety interlocks. Test the seat bar interlock and every control function; overridden safety systems are a serious red flag.
- Hours versus wear. Compact loaders accumulate hours quickly. Check that pedal, seat and grip wear match the meter — see our operating hours guide.
