Choose the DX17Z-7 if...
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 Hyundai R35Z-9A is a 3.5 tonne class zero tail swing compact excavator that gives UK contractors and hirers a lower-cost alternative to the equivalent Kubota, Takeuchi and JCB machines in the same size band. It uses a Yanmar diesel engine rather than an in-house Hyundai power unit at this size, reflecting how compact excavators across brands often share third-party engines and hydraulics. Hyundai's UK dealer coverage for this class is thinner than the market leaders, spread across several regional appointed dealers.
