Strong bucket breakout forceStrong breakout force keeps the <strong>U45</strong>-<strong>3S</strong> 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 <strong>U45</strong>-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 <strong>U45</strong>-<strong>3S</strong> thanks to itsinnovative counter balancing technology, long tumblerdistance, low center of gravity and Double Outer FlangedLower Track Rollers. The <strong>U45</strong>-<strong>3S</strong>’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
