Choose the 301.7 CR if...
The Cat 301.7 CR is Caterpillar's roughly 2 tonne mini excavator, built around the Cat C1.1 engine and backed by Caterpillar's dealer network for parts and service. It is specified on UK sites for the same drainage, groundworks and utility jobs as the Kubota U27-4 and Takeuchi TB216, with buyers often citing Cat's residual values and dealer support over price. It is one of the smaller models in Caterpillar's wider mini excavator line-up, which extends up to around 10 tonnes.

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.
