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.
