Complies
with Interim
Tier IV!
1. Simple forefinger operationUsed for some special applications thatrequire continuous oil flow, such as a brushcutter. The on/off button controlled by theforefinger reduces operator fatigue.
2. Short stroke operating leversThe operating levers require less effort andshorter movements, ensuring improved control,responsiveness and comfort, and reducedoperator fatigue. Only a flick of the wrist isneeded for smooth excavator operation.
3. Proportional flow auxiliary switchA convenient bi-directional switch enables easy operation of hydraulic thumbsand other hydraulic attachments such asaugers and breakers.
4. 2-speed travel switchThe 2-speed travel switch is mounted on the dozer lever for easy operation andcontrol, and advanced, user-friendly travelspeed changes.
5. Wrist restsAdjust the custom wrist rests to your favoriteposition, or just move them aside. Either way,they help reduce arm movement and operatorfatigue for increased job efficiency.
Spacious operating area with deluxe suspension seatMore spacious than standard tail-swing excavators, the KX71-3S’scomfortable operating area helps reduce operator fatigue. The high-back deluxe suspension seat is equipped with wrist rests.Moreover, the height and spring firmness are adjustable, ensuringoptimum comfort for every operator.
Convenient Two-patternSelection System (TPSS)Change between ISO and SAEoperating patterns with a quickflip of the TPSS switch, withouttools or leaving your seat.
User-friendly operation
Comfort that keeps youworking at peak efficiency.
Powerful and dependable, the KX71-3S’s diesel
engine delivers superior horsepower and
performance. It offers low noise and vibration levels,
exceptional fuel efficiency, and complies with the
EPA's 2008 interim Tier IV emissions regulations.

Thumbbracket
The factory-installed thumb bracketand relief valve significantly reducethe time needed to mount theoptional hydraulic thumb.
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.

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.
Superior weight and stabilityThe KX71-3S’s operating weight of 6,305 lbs. (2,866 kg)will make you think you are in an excavator one classlarger. By widening the tumbler distance and track shoesto 5'1'' and 12'' respectively, stability is improved andground pressure reduced. The overall width still allows theexcavator to access narrow openings.
Variable displacement pumpsWith variable displacement pumps, both the oil flow andpressure are adjusted according to the workload. Thepumps even reduce the required engine horsepower forgreater fuel economy, and minimized vibration and noise.
Strong traction forceTo drive you through those softer ground conditions andkeep you working, traction force has been increased byalmost 30% over previous models.
Auxiliary hydraulic oil flowA hydraulic oil flow rate of 13.4 gpm enables the KX71-3S to easily operate a variety of hydraulicattachments, like hydraulic hammers and augers.And a wider selection of attachments means a widervariety of jobs you can accomplish.

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.

ROPS/FOPS canopy and cabThe ROPS/FOPS canopy and cab provide completeprotection from accidental rollovers and falling objects.Both the ROPS and the FOPS meet the applicable, ISO,SAE, and OSHA standards to ensure an extra level ofsafety and security on the job.
Two-piece hose designThe two-piece hose connections for the dozer andboom cylinder hoses simplify hose replacement andreduce downtime.
Protected cylinder hosesThe bucket cylinder hoses are located inside the arm.And the boom cylinder hoses are routed under theboom bottom.
Centralized swivel bearing lubricationGrease ports for the swivel bearing, gear teeth,and swing cylinder pin are convenientlygrouped on the front of the house.
Front pin bushingsTo maximize durability, we’ve introducedbushings on all of the pivot points on the frontattachment and connecting points on theswing bracket.
Fits in tighter placesThe KX71-3S tail swing overhang is only 18",making it easier to avoid obstacles that couldresult in damage to the machine.
Easy maintenanceThe KX71-3S 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.

SafetySafety is designed into every detail of the KX71-3S. 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 the engineis accidentally shut off whilethe front attachment israised, turning the key to the“on” position allows you tosafely lower it.
