Mini Excavators

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.
