Used Caterpillar 309CR Excavators For Auction

The Caterpillar 309CR is a compact mini excavator designed for digging, trenching, grading, and utility work in confined jobsite conditions. It is part of Caterpillar's reduced tail swing excavator lineup, offering improved maneuverability near walls, structures, and obstacles. The 309CR typically features a hydraulic system suited for attachment use, a comfortable operator station, and undercarriage stability for small-to-medium earthmoving tasks. Common applications include landscaping, residential construction, site preparation, and municipal maintenance. As a mini excavator, the Caterpillar 309CR is valued for transportability, versatility, and access to areas where larger excavators cannot operate efficiently.
