U45-3S Zero Tail Swing Excavator - LiveUpdater

U45-3SMore power, more versatility, andmore operator comfort in a compact,high performance excavator.Start with zero tail swing. Add an advanced digital information panel,a load sensing hydraulic system, and an auto idling system. Nowhook on an advanced angle blade with floating position, and youhave the kind of operational performance that makes short work ofeven the toughest digging and dozing jobs.

Clean-runningKubota EnginePowerful and dependable, the U45-3S’sComplieswith InterimTier IV!diesel engine delivers superiorhorsepower and performance. It offers lownoise and vibration levels, exceptional fuelefficiency, and complies with the EPA’s2008 interim Tier IV emissions regulations.Zero-Tail SwingWith zero-tail swing, even the tightest spacesbecome efficient work places. Because the tailalways stays within the width of the tracks, you canturn the house throughout its 360-degree turningradius without damage to the machine orsurroundings. Zero-tail swing also ensures excellentbalance and stability and faster operation, makingthe U45-3S ideal for work in congested urban areas.User-friendly operationNew operating levers require less effort and shorter movements,ensuring improved control and operator comfort. Auxiliaryhydraulics controls are mounted on the right operating lever forsimple operation of attachments. A 2-speed travel switch on thedozer lever permits quicker, more convenient travel speedchanges. Adjustable wrist rests help reduce operator fatigue forincreased job efficiency.

Strong bucket breakout forceStrong breakout force keeps the U45-3S working efficientlyeven under the heaviest of loads. With the dedicated bucketand quick coupler, the bucket breakout force tops 4,393 kg,more than enough for even the toughest excavating jobs.Load sensing hydraulic sysytemWith Kubota’s advanced Load Sensing Hydraulic System,even the slightest lever movements produce smooth andsimultaneous operation of the boom, arm, bucket, and house.Control valves automatically regulate and distribute theoptimum amount of oil to each cylinder based on the weightof the load, resulting in perfectly matched speed, power, andcylinder timing.Boom cylinder protectionThe reinforced v-shape guard protectsthe boom cylinder rod from damagecaused by accidental contact withattachments, rocks, or loads.

W O R K I N G P E R F O R M A N C EAuto idle systemDigital panelKubota’s Auto Idle System improves safety, decreases noise,and reduces fuel consumption by approximately 10%. Theengine automatically decelerates to idling speed fourseconds after the control levers are returned to their neutralpositions. When a control lever is subsequentlymoved, the engine speed automatically returnsto its prior setting. A simple twist of theDial Accelerator smoothly coordinatesspeed and tachometer settings.Informative, interactive, and functional, Kubota’s IntelligentControl System provides timely diagnostic readings androutine maintenance alerts to help reduce downtime andrepair fees. The large digital panel displays current workingconditions, warning indicators, engine rpm and hour meter,fuel, temperature and oil levels. The panel not only lets youknow when fuel is running low, but alerts you during refuelingwhen the tank is nearly full.Adjustable maximum oil flow controlfor auxiliary portThis unique function lets you control the oil flow according toyour needs or the attachment in use. It eliminates the hassleof using tools to change settings manually, so you don’t haveto leave the cabin. When using a tilt bucket, you can slow theflow to get just the right control to gently shape a swale.Alternatively, for a brushcutter, direct the oil flow toone side of the excavatorarm. The system will evenstore your settings for thenext time you need it, savingtime and quickly regulatingthe flow requirements.Adjustable oil flow enhancesperformance and saves fuel.Routine maintenance alert displayLow fuel displayFuel overflow preventionThe U45-3’s fuel system warns you when the tank is nearly full.To begin refueling, turn the ignition key to the OFF position andpress any of the buttons on the digital panel. The system willbegin beeping. When the tank is nearly full, the interval betweenthe beeps will become shorter.Excellent lifting capacity and working rangeA powerful and responsive front working group providesexcellent lifting capacity for all your digging, lifting, andloading jobs. Even when working to the side, using hydraulicattachments, or lifting heavy objects, the U45-3S thanks to itsinnovative counter balancing technology, long tumblerdistance, low center of gravity and Double Outer FlangedLower Track Rollers. The U45-3S’s large bucket capacity,excellent reach and digging depth, ensure that everydigging job is done with maximum efficiency and speed.Third-line hydraulic returnWhen working with one-way hydraulicattachments, such as a breaker or brushcutter, the standard third-line hydraulicreturn system allows oil to flow directlyback to the tank without running throughthe control valves. This contributes toless oil contamination, reduced backpressure, and greater oil flow efficiency.one waytwo way

COMFORT/DURABILITY/MAINTENANCE/SAFETYControlled climate cabNo matter what the weather outside, the U45-3S’s climatecontrolledcab will keep you feeling fresh and comfortable,letting you work faster, better, and longer. If desired, filteredoutside air can be introduced via the external air vent.Front pin bushingsPin bushings are installedat all of the pivot pointsalong the swing bracket,boom, arm, and bucket.Pin type bushings not onlylast longer, they are easierto replace when necessary.Well protected front attachmenthosesTo protect the front hoses from accidentaldamage, they are routed through theswing bracket.NOISE LEVELat operator's ear79dB(A)MaintenanceA wide-opening rear engine cover provides fast and easy accessto daily maintenance items. The side cover provides access to thebattery, radiator and oil cooler, hydraulic oil tank and the controlvalve. Two-piece hose connections for the dozer and boomcylinders simplify hose replacement and reduce downtime.Suspension seatThe deluxe, high back seat is fully adjustable, ensuringoptimum comfort for operators of all sizes. Even the customwrist rests are adjustable to help reduce arm movement andincrease operator comfort.Two-pattern Selection System (TPSS)No need for tools or to leave your seat—a quick flick of theswitch is all it takes to change between ISO and SAE operatingpatterns.Wider foot areaMore spacious than most excavators, the U45-3S’s comfortableoperating area helps reduce operator fatigue.Auxiliary hydraulic systemThe U45-3S’s auxiliary hydraulic system canaccommodate a variety of attachments such as breakersand augers. Standard features include port pipes on thearm, bi-directional auxiliary hydraulic controls, and acontrol value. The auxiliary hydraulic connections arelocated within easy reach and incorporate short hosesthat are less likely to become tangled or damaged.
