Caterpillar 308 CR

The Cat 308 CR is a compact-radius mini excavator in Caterpillar’s current 7- to 10-ton range. Official U.S. product specifications describe a machine built around a Cat C3.3B diesel that meets U.S. EPA Tier 4 Final and EU Stage V standards. The figures below come from Caterpillar’s public 308 CR product page and apply to that published configuration. They are not a quote, and they do not mean a unit is available from any dealer listed here.

What this machine is

A compact-radius mini excavator keeps most of the counterweight rotation within the width of the tracks, which helps on tighter jobs such as residential utilities, site prep, and work next to walls or traffic. Buyers usually look at net power, operating-weight range, dig depth with the chosen stick, and hydraulic pump flow. Caterpillar publishes both a standard stick and a longer stick for this model; dig depth and reach change with that choice. LoanHelp can take a financing inquiry on a machine in this class and is not the lender.
