The Yanmar ViO20-6 steps up from the ViO17 into the roughly 2 tonne mini excavator class, still with Yanmar's true zero tail swing geometry for working in confined spaces. It competes with the Caterpillar 301.7 CR and similarly sized Kubota and Takeuchi machines for UK groundworks and utility hire jobs. Its fixed rather than variable undercarriage keeps the design simpler than some rivals, at the cost of not being able to narrow down for transport.
