The U27-4 tight-tail-swing excavator features adjustable auxiliary-flow hydraulics, an auxiliary diverter valve, and two-speed automatic downshift travel. An enclosed-cab option with heat is available. The U27-4 is powered by a Kubota Tier 4-F engine, designed to minimize noise and vibration, and an auto-shift feature automatically shifts travel speed from high to low, depending on traction and terrain.
