Not a major player in the UK market, thanks to Caterpillar’s sheer size, you will always find a decent number of Caterpillar mini-excavators for sale in the UK at PlantPages. The CAT mini digger range starts at under a tonne operating weight with the 300.9 range and extends to 10 tonnes, but the models over 8 tonnes you will find in the CAT tracked excavator category here at PlantPages. The model numbering for the CAT mini-digger range is similar to the larger machines. They all start with a ‘3’ for the 300 series. The ending of the model number represents the weight of the machine in metric tonnes. So a 301.4C is a Caterpillar mini-excavator with an operating weight of around 1,400kgs (and the ‘C’ denotes that the machine is from around 2016).
