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.
A third-line hydraulic-return system allows oil flow directly to the tank when working with one-way hydraulic attachments, such as a breaker or brush cutter, allowing greater flow efficiency, reduced back pressure, and reduced heat, says Kubota.
The U27-4 can dig to 9 feet 5 inches and has a bucket-digging force of 7,014 pounds. The new machine uses two variable-displacement pumps, which are designed to allow simultaneous operation of boom, arm, bucket, and swivel. An optional enclosed cab is available.
