WithoutAngle BladeWithout the angleblade feature,time-consuming,repetitiverepositioning atright angles to thetrench is required.
With Angle BladeMoving only in aforward directionone time, which isequivalent to atrencher backfillingits one side, theKX121-3S AngleBlade excavatorbackfills smoothlyand efficiently.
What makes our KX121-3S Angle Bladeexcavator so productive? Check it out.
Float positionYou don’t need to adjust the dozerheight to make a clean groundsurface—after backfilling, just travelbackward along the covered ditch withthe dozer in the float position. Groundfinishing work is now fast and easy!
Easy operation Up, down, left and right—the angle blade can bemoved and positioned withjust a single lever.
Save time and work more efficiently. With a simplemovement of the dozer lever, the hydraulic angle bladecan be angled to the right or left to push soil to the sideas the machine moves forward, eliminating the need forrepetitive repositioning at right angles when backfillingtrenches.
Tight spotsThe angle blade lets you work efficiently in confined spaces,alongside walls, and near busy roads. No wider than thetracks, it’s also easy to transport between jobs.

The power and versatility to takeon a variety of tough jobs.
Load-sensing hydraulic systemYou no longer need to change lever strokes to adjust the amount of oilrequired for varying job loads—control valves automatically regulateand distribute the optimum amount of oil to each cylinder based on theweight of the load, resulting in perfectly matched speed, power, andcylinder timing. Even the slightest operator movements produce smoothand simultaneous operation of the boom, arm, bucket and house.
Auxiliary hydraulicsAuxiliary hydraulic hoses are routed to the arm to accommodate avariety of attachments such as breakers and augers. The auxiliaryhydraulic connections are located on the arm within easy reach andincorporate short hoses that are less likely to become tangled ordamaged. The system includes bidirectional auxiliary hydrauliccontrols, as well as a control valve.
Wide working rangeThe KX121-3S’s powerful and responsive front working group can handle allyour digging, lifting, and loading jobs. With its large bucket capacity, long reachand formidable digging depth, the KX121-3S meets or exceeds most jobrequirements on the construction site.
Strong bucket breakoutEven when heavily loaded, the KX121-3S won’t slow down, thanks to its powerfulbreakout force. With the dedicated or quick coupler bucket, the bucket breakoutforce is more than enough for even the toughest excavating jobs.

Thumbbracket
The factory-installed thumb bracketand relief valve significantly reducethe time needed to mount theoptional hydraulic thumb.
Auto idling system
Save fuel with Kubota’s Auto Idle. When the control leversare in neutral for more than 4 seconds, the engineRPM automatically idles. Move any control leverand the engine RPM immediately returns. Thisinnovative feature reduces noise and exhaustemissions while reducing operating costs.
Adjustable maximum oil flow control forauxiliary port
The digital instrument panel lets you control the oil flowaccording to your needs or the attachment in use. It eliminatesthe hassle of using tools to change settings manually, so youdon’t have to leave the cabin. When using a tilt bucket, you canslow the flow to get just the rightcontrol to gently shape a swale.Alternatively, for a brush cutter,direct the oil flow to one side ofthe excavator arm. The systemwill even store your settings forthe next time you need it, savingtime and quickly regulating theflow requirements. Adjustableoil flow enhances performanceand saves fuel.
Routine maintenance alert display Low fuel display
Extraordinary stability and lifting capacityInnovative counter-balancing technology provides superiorexcavator stability. Long tumbler distance, a lower center ofgravity, and double flanged lower track rollers combine todeliver safe and effective performance when working to theside or with hydraulic attachments, or lifting heavy objects.
Rear corner protectorsTwo heavy-duty protectors—one on each rear corner—protect the engine hood and side covers from damagewhen working in tight spaces.

Digital panel
A digital panel and the Kubota Intelligent Control System(KICS) help reduce excavator downtime and repair fees byproviding accurate and timely diagnostic readings and routinemaintenance alerts. The panel not only lets you know when fuelis running low, but warns you during refueling when the tank isnearly full.
Simple maintenance keeps the KX121-3S working longer.
ROPS/OPG (TOP Guard, LevelⅠ) canopy and cabThe ROPS/OPG (TOP Guard, LevelⅠ) canopy and cab providecomplete protection from accidental rollovers and falling objects.Both the ROPS and the OPG (TOP Guard, LevelⅠ) meet theapplicable ISO, SAE, and OSHA standards to ensure an extralevel of safety and security on the job.
Two-piece hose designThe two-piece hose connections for the dozer and boomcylinder hoses simplify hose replacement and reduce downtime.
Protected cylinder hosesThe bucket cylinder hoses are located inside the arm. And theboom cylinder hoses are routed under the boom bottom.
Centralized swivel bearing lubricationGrease ports for the swivel bearing, gear teeth, and swingcylinder pin are conveniently grouped on the front of the house.
Front pin bushings To maximize durability, we’ve introduced bushings on all ofthe pivot points on the front attachment and connectingpoints on the swing bracket.
Third-line hydraulic returnWhen working with one-way hydraulicattachments, such as abreaker or brush cutter,the standard third-linehydraulic return systemallows oil to flow directlyback to the tank withoutrunning through thecontrol valves. Thiscontributes to less oilcontamination, reducedback pressure, and
Easy maintenanceThe KX121-3S is a breeze to maintain. The side and rear coversopen wide and the main components are centrally located, givingyou quick and easy access to all vital areas, including the engine,fuel tank, water separator, radiator, coolant reservoir, air filter,control valve and hydraulic tank.
Boom cylinder coverReinforced to provide maximum protection, the boom cylinder coverfeatures a thick, V-shape design that deflects accidental contactsfrom the hydraulic breaker tool and prevents damage to the boomcylinder rod.

SafetySafety is designed into every detail of the KX121-3S. An EngineStart Lockout System prevents the engine from starting whenthe safety levers are lowered. A Safety Lever Lockout Systemhelps prevent unexpected excavator and attachment movementwhen entering or exiting the machine. An Auto House ParkingBrake automatically locks the house in the position it was inwhen the engine was shut off, eliminating the need for a swinglock pin. It also makes the excavator more compact duringtransport and more secure when parked on an incline.
AccumulatorThe accumulator makes replacing attachments safer and moreefficient. Turning the key to the “on” position clears residualpressure in the auxiliaryhydraulic hose. If theengine is accidentallyshut off while the frontattachment is raised,turning the key to the“on” position allows youto safely lower it.
