Kubota Mini Excavators: the U and KX Series Split on Tail Swing, Plus the Hydraulically Retractable Track Gauge on the Smallest Models
Kubota splits its mini excavators into two families: the KX-series with conventional tail swing (the rear overhangs the tracks when the upper structure rotates) and the U-series with tight to zero tail swing (the rear stays within the track width). The "Kubota Mini Excavator" bucket holds 51 models spanning 5 to 46 kW, from the tiny K008-3 up to larger U- and KX-series machines.

The U-series is built for working right against walls, fences or buildings, since the machine doesn't hit anything as it rotates — examples include the U15, U25, U27 and U35. The KX-series (e.g. KX41-3, KX91-3) trades that for the stability of conventional tail swing on open jobsites.
The digit after the hyphen marks the emissions generation: Kubota has revised its engine families several times, from E2 (Tier 2) through E3/E3B (Tier 3) to E4 (Tier 4 Final) and E5 (EU Stage V) — parts aren't necessarily interchangeable across generations.
On the smallest models such as the K008-3, the track gauge can be hydraulically retracted so the machine fits through narrow doorways or garden gates, then widened back out to the sturdier working gauge on site; the larger KX- and U-series models, by contrast, have a fixed track gauge.
When buying used, check the generation alongside cylinder count (3 or 4, depending on class) and the condition of the undercarriage and hydraulic cylinders — a common wear point especially on the compact K- and U-series machines.

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.
- Ask about parts availability for this build year — the running costs hang on it.
