Kubota Compact Excavator



Powerful and easy to operate, the KX080-4S is also environmentally


friendly, making it the number one choice for all your power utility excavation needs.












Common Rail System and Diesel Particulate Filter (DPF) Muffler

  • Common Rail System and Diesel Particulate Filter (DPF) Muffler

The Common Rail System (CRS) electronically controls the fuel injection timing and amount in stages rather than all at once for optimal combustion. The results are great efficiency, better fuel economy and less engine noise. Its combination with the Exhaust Gas Recirculation (EGR) and Diesel Particulate Filter (DPF) Muffler reduces emissions to make the KX080-4s engine Tier IV certicicated.


Automatic regeneration system

  • Automatic Regeneration System

Kubota's original automatic regeneration system automatically burns accumulated particulate matter (soot) in the DPF muffler to keep the muffler clean for longer operation. For safety reasons, automatic regeneration can be turned off with the inhibit switch when the excavator is operating in areasthat contain flammable materials.

  • Introducing ECO e Plus

Kubota's original ECO e Plus prioritizes fuel economy, and supports the environment. In Standard mode, KX080-4s delivers up to 8% productivity improvement and 14% fuel savings over the previous model. For even greater fuel savings, activate the ECO e Plus Mode with the flick of a switch for up to 16% fuel savings over Standard Mode. Other benefits of the new ECO e Plus mode include a reduction of noise as well as improved front attachment operations.

  • 2-Pump Load-Sensing Hydraulic System

A new 2-pump load-sensing system improves the overall smoothness of operations when using front attachments, lettings you effortlessly perform simultaneous operations. You'll notice the difference when simultaneously operating the front working group while traveling.

  • Tight Tail Swing and Compact Machine

Thanks to its contoured, tight tail design created by the shorter rear overhang, the KX080-4s has excellent stability, can handle a wider range of loads, and can work in more restrictive spaces. The compact 7' 2.6" width of the under-carriage makes it ideal for working in close conditions, and much easier to transport between job sites.

Proportional Flow Control of Auxiliary Circuits (AUX1/2) and Maximum Oil Flow Settings

  • Proportional Flow Control of Auxiliary Circuits (AUX1/2) and Maximum Oil Flow Settings

Two auxiliary circuits (AUX 1 & 2) come standard on the KX080-4S. The convenient thumb-operated switch allows easy proportional flow control of the auxiliary circuit, while a forefinger-operated switch allows easy proportional flow control of the auxiliary circuit, while a forefinger-operated on/off switch enables simple operation of special applications that require a constant oil flow. The maximum oil flow setting is conveniently adjustable from the digital panel. You can even program up to five oil flow rates corresponding to specific attachments so they can be quickly retrieved for the next job.


Adjustable Maximum Oil Flow Control for Auxiliary Port

This unique function lets you control the oil flow and eliminates the hassle of using tools to change settings for the next time you need it. Adjustable oil flow enhances performance and saves fuel.

  • Auto-Idling System

Save fuel with Kubota's Auto Idle. Reduce engine RPM instinctively when high engine speed isn't needed. When the control levers are in neutralfor more than 4 seconds, the engine RPM automatically idels. Move any control lever and the engine RPM immediately returns. This innovative feature reduces noise and exhaust emissions while reducing operating costs.


Hydraulic Angle Blade

  • Hydraulic Angle Blade (option)

Save time and work more efficiently. With a simple movement of the new thumb operated rocker switch on the dozer lever, the hydraulic angle blade can be angled to the right or left to push soil to the side as the machine moves forward, eliminating the need for repetitive repositioning at right angles when backfilling trenches.


A. Float Position

You don't need to adjust the dover height to make a clean ground surface-after backfilling, just travel backward along the covered ditch with the dozer in the float position. Ground finishing work is now fast and easy!

B. Easy Operation

Up, down, left, and right - the angle blade can be moved and positioned with just a single lever.

New Digital Panel

  • Easy-Open Front Window

Unlike many excavator windows, the front glass window of the KX080-4S opens with ease. Just flip the latch on the side of the window and slide it up. A gas-assist mechanism makes this action almost effortless.

  • Cab Guttering

The KX080-4S features a guttering system to the cab's roof. This helps prevent rainwater from entering the cab, even when the window is open on a rainy day.


New Air Conditioner

  • Air Conditioner

Overall air circulation in the cab is better than ever, thanks to a stronger cooling/heating unit and the positioning of six vents. Airflow is also directed towards the operator's face for better all-around comfort.



  • Deluxe Suspension Seat

Cup Holder

  • Cup Holder

With the convenience of a bigger cup holder, you can quench your thirst and work longer without leaving the cab. Or store your cell phone*. The charging port is located conveniently close by.

*Cell phones should not be used during machine operation.

  • Movable Console


  • TPSS

The Two-Pattern Selection System can shift control styles, whether it's the ISO pattern or the SAE backhoe pattern, with the simple turn of a switch.
