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.
