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 harmful emissions to make the KX080-4 Tier IV compliant.
Kubota’s original automatic regeneration system automatically burns accumulated particulate matter (soot) in the DPF muffler when the engine exceeds 1800 rpm 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 areas that are prone to fires.
Proportional Flow Control of Auxiliary Circuits (AUX1/2) and Maximum Oil Flow An auxiliary circuit (AUX2) comes standard on the KX080-4. The convenient thumb-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.
Save time and work more efficiently. With a simple movement of 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.
Thanks to its contoured, tight tail design created by the shorter rear overhang, the KX080-4 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.
Informative, interactive and functional, Kubota’s Intelligent Control System LCD panel accurately displays timely diagnostic readings and routine maintenance alerts. You’ll be kept informed of your current working conditions, engine RPM, temperature and oil levels. These new features help reduce downtime and costly repair fees.
Overall air circulation in the cab has been improved, 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-round comfort.
All three of the excavator’s access panels can open at once. This allows you to easily inspect and view the centrally located components of the KX080-4. You can easily access the hydraulic components under the center hood, or the battery, oil filter and tool box under the right hood. Maintaining your excavator has never been this easy.
The variable fan drive provides the right amount of cooling efficiency by regulating the engine fan speed according to the ambient temperature after the air passes through the radiator. The benefits are reduced fan noise and fuel savings through effective use of engine output.
Kubota’s high-back suspension seat has been designed for maximum operator comfort and to minimize fatigue during extended machine operation. The deluxe reclining seat offers weight compensation, firm adjustable wrist support and rectractable seat belts.
The OSHA-certified ROPS/OPG (Top Guard) cabin provides protection in the event of accidental rollovers and falling objects.
