306E2

Mini Excavators

The new Cat 306E2 Mini Hydraulic Excavator has been designed and built by Caterpillar to deliver exceptional superior performance, productivity, controllability and reliability at lower operating cost. The extremely fast, smooth and responsive hydraulic movement offers greater job accuracy and efficiency. The standard tail swing design incorporates a counterweight that extends further back on the machine to maximize the machine stability for lifting and digging. The 306E2 sets the standard for conventional tail swing excavators in the six-ton size class.
