SUPERIOR PERFORMANCE The U27-4 is designed to handle the challenging jobs that are way out of reach for bigger excavators. The zero-tail swing lets you travel through and turn smoothly in tight spaces with ease. And features like a powerful digging force and easy simultaneous operation of four functions and more, offer performance you can truly rely on. Kubota original engine The U27-4 is powered by Kubota's tough and reliable engine. Engineered with the power to maximise digging and lifting performance, it also delivers minimised noise and vibration. Zero-tail swing With zero-tail swing, even the tightest spaces become efficient work places. The tail's minimal protrusion outside the track width lets you turn throughout its 360-degree turning radius with complete confidence and safety and fewer accidents with things around you. It also maintains better balance over conventional zero-tail swing excavators and faster operation, making this mini-excavator ideal for work in congested urban areas and inside buildings. Standard AUX1 & AUX2 and proportional flow control of auxiliary circuit U27-4 is available with a standard AUX1 and AUX2. It enables to further increase machine versatility. The convenient thumb-operated switch on the lever allows easy proportional flow control of the auxiliary circuit. Powerful digging force The U27-4 delivers an impressive bucket digging force. Its powerful and well-balanced arm and bucket allow the operator to dig faster, deeper (2820 mm) and more efficiently even in the toughest conditions. It offers powerful workability and excellent stability without the need of additional weights that are often required by other zero-tail swing excavators. Simultaneous operation of four functions When the simultaneous operation of the boom, arm, bucket, and swivel are required, two variable pumps will distribute an accurate amount of oil flow to each actuator according to the lever stroke. This process enables continuous high performance digging and dozing. Third-line hydraulic return When working with one-way hydraulic attachments, such as breaker or brush cutter, the standard third-line hydraulic return system allows oil to flow directly back to the tank without running through the control valves. This contributes to less oil contamination, reduced back pressure, and greater oil flow efficiency. Auto-shift The auto-shift automatically shifts travel speed from high to low, depending on traction and terrain, allowing smoother operation when dozing and turning. Left control lever Right control lever Adjustable Maximum oil flow control AUX circuit 1 & 2 The AUX oil flow adjust dial is conveniently located on the top of meter panel. Rocker switch for AUX2 and Swing boom The round switch on the left lever permits easy switching between AUX2 and the Swing function. Also it provides more foot space for greater operator comfort. DELUXE INTERIOR The luxurious interior features a wider entrance, greater legroom and a deluxe seat. Operability is greatly enhanced with more easy-to-use features than ever before. E B D A. Flat Foot Space The flat foot space enhances comfort by providing ample leg room to reduce fatigue even during long hours of operation. B. 2-speed Travel Switch By placing the 2-speed travel switch on the dozer lever, dozing operations can be done faster and easier. C. Cup Holder With the convenience of a bigger cup holder, C you can quench your thirst and work longer without leaving your seat. D.
