Choose the ZX33U-6 if...
A general-purpose mini digger for landscaping, utilities and small groundworks contractors who need to work in gardens, driveways and other access-restricted sites. Its zero tail swing lets it turn on the spot without swinging into fences or walls.
Full specifications →Choose the ViO20-6 if...
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.
