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.
