In 1993, YANMAR introduced the world’s first zero tail swing excavator. Today, the ViO50-6A turns completely within its own tracks, with the stability of a conventional excavator. So you can trench and dig in the extremely tight spaces that other excavators simply can’t get to. Add to that a new 39-hp Final Tier 4 Yanmar diesel engine that sacrifices none of the legendary power and unmatched fuel efficiency.
