The Caterpillar 306 is a mini-excavator with an operating weight of 6411 kg and an engine output of 56 hp. It is equipped with a bucket capacity of 0.16 m3, placing it in the compact excavator segment suited to confined and medium-duty earthmoving work. As a Caterpillar product, it carries the brand's established reputation for build quality and parts availability across European markets.
Mini-excavators in the 306 class are well suited to utility trenching, landscaping, foundation work on restricted sites, and urban infrastructure projects where machine footprint is a practical constraint. The combination of digging reach and compact dimensions makes this class a common choice for contractors working in residential, municipal, and light civil construction environments. Attachment versatility, including breaker and auger compatibility typical of this class, extends the machine's utility across multiple trade disciplines.
Prospective buyers should conduct a thorough visual and operational inspection covering undercarriage wear on tracks and rollers, condition of the boom and arm pins and bushings, and integrity of hydraulic lines and cylinder seals. Service history documentation is an important indicator of maintenance discipline, particularly for the engine, hydraulic system, and filtration intervals. Buyers should verify that the bucket and any auxiliary attachments are included and functional, and should operate the machine through its full range of motion to identify any drift, hesitation, or abnormal noise in the hydraulic circuits before completing a purchase.
The Caterpillar 306 sits within a European market average price of EUR 14617, with units in the typical traded range of EUR 5000 to EUR 6500 representing the lower end of the available inventory spectrum. Buyers evaluating this machine should also consider comparable models in the segment, notably the JCB 86C-1 and Komatsu PC60, both of which compete directly in terms of size class and application suitability. Price positioning relative to these competitors will depend on machine age, condition, and configuration at point of sale.
