Caterpillar 428: excavator-loader, series and inspection
Caterpillar 428 — a popular excavator-loader used for road, communication, and construction work. We look at the D, E, and F series, key features, and what to check when buying a used 428.
428 in brief
Cat 428 — a versatile machine with a front loader bucket and rear excavator arm. It's used for digging, loading, road, and communication work, making it suitable for both construction companies and municipal services.
Operating weight is usually around 7–8 tonnes, with a digging depth of over 5 metres. Due to its popularity, there's a large supply of used machines on the market, and parts are easy to find.
Series — what's the difference
Older versions are simpler, with less electronics. The D and E series improved comfort, while the F series enhanced fuel efficiency and cabin ergonomics. Newer machines offer better visibility and a quieter cabin.
Some machines have a side-shift for the excavator arm, while others have a fixed position. Hydraulics also vary: some have additional lines for a hammer or other attachments.
Engines and transmission
The Cat 428 is powered by a four-cylinder Cat diesel engine. Newer versions feature systems that meet stricter emission standards, and their condition is crucial.
The transmission is either a mechanical reverse or Powershift. The choice depends on the version: Powershift is more convenient for frequent forward and reverse driving, while mechanical is simpler and cheaper.
What to check when buying a used 428
Check the engine hours, cold start, smoke, and leaks. Test the transmission and brakes: the shifts should be smooth, with no juddering or strange noises.
Inspect the jacking points and tow hooks for wear and tear (play is a common issue), cylinder leaks, and the condition of the stabilizer bar.

Comparison of 428 versions
| 428D | 428E | 428F | |
|---|---|---|---|
| Who it's for | For budget work | For everyday work | For intensive and comfortable work |
| Transmission | Often manual | Manual or Powershift | Often Powershift |
| Comfort | Basic | Better | Good |
| Price in the used market (relatively) | Budget-friendly | Mid-range | Premium |
For a budget construction firm, a 428D or E with a good history might suffice. If you're working intensively and comfort is key, look for an F series.
Pros
- Versatility – towing and loading in one vehicle
- Wide range of used options available
- Good supply of Cat parts
- Basic maintenance
Cons
- Play in the controls and steering in older vehicles
- Less power than specialist excavators and loaders

Frequently asked questions
How does the 428 differ from the 432?
The 432 is slightly larger and more powerful than the 428, with a longer arm and deeper digging depth. The 428 is cheaper and easier to manoeuvre.
Is it worth buying a 428 with Powershift?
Yes, if the transmission is working smoothly. Powershift is more comfortable for loader work, but repairs can be more expensive than mechanical reversers.
What are the most common 428 problems?
Most commonly — play in the controls and steering, hydraulic leaks, and transmission wear. You'll mostly spot these during an inspection.
