Yanmar ViO Series — the line that invented the zero-tail-swing excavator
The ViO Series covers 13 models in the database from 9.2 to 50.0 kW, ranging from a compact mini-excavator to a mid-size jobsite unit. What sets the line apart from other compact excavators isn't primarily a size class but a design principle: zero tail swing, where the rear of the machine never extends beyond track width during a full rotation.

Yanmar brought this principle to market in 1993 with the ViO line, making it the first manufacturer with a true production zero-tail-swing excavator. Because the usual rear counterweight overhang was gone, engineers had to relocate the counterweight elsewhere in the chassis to avoid losing lift capacity — a concept still carried forward today, now in its seventh model generation.
Zero tail swing made the ViO line the standard tool for work along building walls, in trenches next to traffic, or in tight courtyards, where a conventional excavator would clip something while swinging.
For a used ViO excavator, pay particular attention to the slew bearing and the condition of the counterweight balancing system; beyond that, track wear and cylinder seals matter as on any mini-excavator.
In short: reading "ViO" means buying the zero-tail-swing principle Yanmar invented over 30 years ago, not primarily a size class.

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.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
