The CAT 303.5C CR is Caterpillar’s classic 3.5-ton compact radius mini excavator, a benchmark machine for landscaping renovation, municipal pipeline construction, indoor demolition, yard excavation, orchard and greenhouse projects, as well as small-scale rock-breaking works across Europe and America. Its compact CR tail-swing design ensures the upper rotating structure never extends beyond the track width, preventing scratches on walls and buildings when working in basements, narrow lanes and residential construction sites. Fitted with a genuine Cat C1.7 turbocharged engine paired with a proven load-sensing hydraulic system, it delivers ample power with low fuel consumption, offering reliable durability across light-duty digging, rock breaking and backfilling applications.
