The 2021 Caterpillar 306CR is a compact excavator with a 57.9‑hp turbo diesel engine and hydrostatic 2-speed travel system. Its zero-tail swing and rubber-track chassis provide stability and maneuverability in tight workspaces, while the long-arm configuration allows for extended reach and digging depth.
Equipped with a hydraulic thumb, auxiliary hydraulics, and quick coupler, the 306CR handles attachments efficiently, including the included Cat tooth bucket. The backfill blade and boom swing increase operational flexibility, while the cold-weather package ensures reliable operation in all conditions.
Inside the enclosed ROPS cab, the operator enjoys A/C, heat, and ergonomic controls for comfort and efficiency. With well-maintained tracks, low hours, and robust performance, this 306CR is ready for immediate deployment on construction, landscaping, or utility projects.
