For contractors working in restricted yards or alongside live structures who still need the dig performance of a 20-tonne-plus machine. The reduced tail swing keeps the counterweight closer to the tracks than a standard crawler excavator of this size.

Buy or hire the ViO17 if...
The Yanmar ViO17 is a true zero tail swing mini excavator built for working tight to walls, fences and parked vehicles without the counterweight overhanging, a common requirement on UK residential and urban groundworks jobs. It sits in the same roughly 1.7-1.9 tonne hire class as the Takeuchi TB216 and Kubota KX019-4. Yanmar's compact equipment range is less widely stocked across UK hire fleets than Kubota or JCB, but it has a following among contractors who rate its digging force for its size.
