John Deere wheel loaders — what the number and end letter say about class
At John Deere, the number in the model name places the wheel loader in a size class: 200-series models like the 244 count as compact loaders, while 400- and 500-series models like the 444 or 544 are mid-size loaders with correspondingly more engine power and bucket capacity.

The letter at the end long indicated the generation (such as J or H); John Deere has since added a performance-tier marker for its midsize loaders as well: G denotes the base or economy version, while P and X mark higher equipment and performance tiers.
The “John Deere Wheel Loader” collective entry therefore mixes different generations and performance tiers side by side, from small compact loaders like the 204L up to large jobsite loaders. Engine power ranges from around 38 kW at the lower end up into three-digit kW figures for the largest models.
When buying used, check the quick coupler, lift linkage and axles, and run the tilt-bucket hydraulics through their motions, since loaders see very different wear depending on quarry or yard duty.
In short: the number signals the size class, the end letter the generation or performance tier — models like the 204L, 244J or 444 show how wide a range sits under one register entry.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
