A 70-horsepower Kubota diesel

engine provides the energy behind

the powerful KX080-3 working

performance. The 3769 cc direct-

injection engine contributes to easy

starting on those cold mornings, low

sound levels, and energy-saving fuel

economy. And because Kubota is

environmentally conscious, the

engine complies with the EPA’s

interim Tier IV emissions

regulations—without losing

horsepower or ease of operation.

Auto Idling System

Save fuel with Kubota's Auto Idle. Reduce engine RPMinstinctively when high engine speed isn’t needed. Whenthe control levers are in neutral for more than 4 seconds,the engine RPM automatically idles. Move anycontrol lever and the engine RPMimmediately returns. This innovativefeature reduces noise and exhaustemissions while reducingoperating costs.

Electric Fuel Refilling PumpThe KX080-3’s new, standard refuelling pumpincludes a hose long enough to refuel from a

fuel tank. With this pump,the tank can be completelyfilled in approximately threeminutes with just a simplepush of a button. Uponcompletion, an auto-stopfeature ends fuelling toeliminate spillage.

3-pump Load-Sensing Hydraulic SystemKubota’s load-sensing hydraulic system guaranteessmoother handling, regardless of load size. It allowshydraulic oil to flow according to your precise needs.The KX080-3’s new 3-pump load-sensing system alsoallows you to perform simultaneous operations, suchas dozing and utilising front attachments, withoutlosing speed.

Auto-ShiftNow your excavator moves how you want it to—evenat high speeds. When working with heavy loads,making turns or backfilling trenches, the systemautomatically downshifts for more torque. This shift isso smooth and seamless you’ll feel as though you’venever left high speed.

Stability and WorkingRange

The KX080-3 design combines smooth,harmonised, hydraulic systemperformance with optimum balance in atight tail swing excavator for versatilestability. Together with extendeddumping height, a swingboom, large bucketcapacity and deepdigging depth, theKX080-3 can match orexceed the latest high-capacity dumper, tipper,and construction siterequirements.

Industrial Digging Force

You need exceptional power when trenching throughcompacted soil. With the KX080-3, elevated productivitylevels are certain with the combination of 6,650 kgbucket force and 3,880 kg arm forces. The KX080-3powers through those demanding applications so thatyou can quickly move on to the next job.

The power and technology totackle almost anything.

Dozer BladeWith the high-capacity dozerblade, you don’t need separatemachines for site prep, digging,and finish work. Save money,time, and personnel!

360 mmThe tight tail swing of the KX080-3maximises machine balance andincreases versatility.

Tight Tail SwingThe KX080-3 is designed with a shorter rearoverhang. Thanks to this contoured, tight tail design,the KX080-3 is more stable, can handle a widerrange of loads, and can work in more restrictivespaces than traditional tail swing excavators.

Compact MachineWidthThe KX080-3 is narrower than competitor models.Its compact 2,200 mm width makes it ideal forworking in close conditions, and much easier totransport between job sites.

Adjustable Maximum Oil FlowControl for Auxiliary Port

This unique function lets you control the oil flowaccording to your needs or the attachment in use. Iteliminates the hassle of using tools to change settingsmanually, so you don’t have to leave the cabin. Whenusing a tilt bucket, you can slow the flow to get just theright control to gently shape a swale. Alternatively, for abrush cutter, direct the oil flow to one side of theexcavator arm. The system will even store your settings

for the next time youneed it, saving time andquickly regulating theflow requirements.Adjustable oil flowenhances performanceand saves fuel.

Third-line Hydraulic ReturnWhen working with one-way hydraulicattachments, such as a breaker orbrush cutter, the standard third-linehydraulic return system allows oil toflow directly back to the tank withoutrunning through the control valves.This contributes to less oilcontamination, reduced backpressure, and greater oil flow efficiency.

Two-Piece Hose DesignKubota’s innovative two-piece hose design for the dozerblade reduces hose replacement time by nearly 60%compared to non-joint types. This design virtuallyeliminates the need to enter the machine for maintenance.

Designed for dependability, built to last.

Triple Opening Bonnet

All three of the excavator’s access panels can open atonce. This allows you to easily inspect and view thecentrally located components of the KX080-3. Youcan easily access the hydraulic components underthe centre hood, or the battery, oil filter and tool boxunder the right hood. Maintaining your excavator hasnever been this easy.

ROPS/FOPS Cabin

The ROPS/FOPS certified cabin provides protection inthe event of accidental rollovers and falling objects.

Movable Console

Raise the safety control lever and the console moveswith it, providing more room for entry and exit. Toprevent unexpected machine movement during entryor exit, all control levers are then disabled until theconsole is back in place.

Boom Anti-Drop Valve

Standard equipment onthe KX080-3, the anti-drop valve prevents anelevated load fromdroppingunexpectedly.

Overload Alarm

To better ensure workersafety and equipmentcondition, the KX080-3comes equipped withan overload alarm. Thisalarm alerts theoperator when loadcapacity has beenexceeded, helping toprevent possible injuryto workers and costlydamage to theexcavator and worksite.

Swivel Negative Brake

The swivel negative brake automatically locks theswivel function in its current position. This preventsunexpected machine movement. It’s particularlyuseful during work or when transporting theexcavator between worksites.
