A midi excavator for groundworks, utilities and landscaping contractors. At 5.3 tonnes it arrives on a lorry rather than behind a car. It digs to 3434mm. Zero tail swing means the back of the machine stays inside the tracks when it slews, so it can work tight against a wall or in one lane of a road.

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.
