This excavator has an easy-to-use engine, a hydraulic system that maximizes engine output, and saves fuel by keeping a constant balance between pressure and flow. Also known as trackhoes or diggers, excavators are easy to control in multiple function applications, like precision grading. Just punch in the grading mode and you'll be smoothly propelled across the top of the embankment. This range of excavators is ideal for construction sites with room to maneuver, but it has limited tail swing for maneuverability.
