The Develon DX17Z-7 is the smallest excavator in the Develon range, formerly sold as a Doosan model before the 2023 rebrand, and competes for the same confined-space and landscaping hire jobs as the JCB 8008 CTS and Kubota KX019-4. UK dealers that previously stocked it as a Doosan now sell and service it under the Develon name with the same parts and support lines. It gives hire companies a mini excavator option outside the usual Kubota, JCB and Takeuchi trio at a similar size point.

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.
