The CAT 303 CR is Caterpillar’s 3.5-ton zero-tail-swing compact mini excavator. CR stands for Compact Radius, the zero tail swing design. Positioned between the 2-ton 302 CR and the 4-ton 304 CR, it balances outstanding maneuverability in confined job sites and enhanced heavy-duty digging capacity. It features ample power, low operating costs, multi-functional performance and fast return on investment. It is widely suitable for yard renovation, municipal pipeline trenching, landscaping, light indoor demolition, orchard clearing, small foundation excavation, rural ditch dredging, farmland improvement and construction in tight basement spaces. It serves as a core profitable workhorse for overseas landscape service providers, municipal maintenance crews, private contractors and small-to-medium rental yards.
