Product Overview

The Caterpillar 306 is a classic 6-ton class compact hydraulic crawler excavator manufactured by Caterpillar Inc., widely recognized in the global compact equipment market for its rugged reliability, stable power delivery and industry-leading durability. It is a benchmark model in the 6-ton segment, perfectly suited for small-scale earthmoving, municipal maintenance, landscaping and rural infrastructure projects. This pre-owned 306 retains all original factory core components including the genuine Cat C2.2 turbo diesel engine and main hydraulic system. Each unit passes a strict 120-point pre-delivery inspection, with verified no major accident history, no structural damage, and complete scheduled maintenance files.

As a high cost-performance alternative to brand-new compact excavators, this used Caterpillar 306 delivers over 90% of new-machine performance at only 35%–50% of the acquisition cost. Its compact footprint and flexible maneuverability allow efficient operation in confined spaces. It is the preferred workhorse for small construction contractors, equipment rental fleets, landscaping service providers and municipal engineering teams, featuring short delivery lead time and globally accessible genuine spare parts supply.
