Common Rail & DPF
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 KX040-4 Tier IV-compliant.



Auto Regeneration
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 areas that may pose a fire hazard.


For tough digging applications, use Standard Mode and experience a 3% productivity improvement over the prior model and use less fuel, up to 12% less. Activate Eco Mode with the flick of a switch for up to 9% fuel savings over Standard Mode.


Auxiliary Flow Control
The KX040-4 is available with a standard auxiliary circuit. The convenient thumb-operated switch on the control lever allows easy proportional flow control of the auxiliary attachment, while a forefinger- operated on/off switch enables simple operation of attachments that require a constant oil flow. The maximum oil flow setting is conveniently adjustable from the digital panel. Up to five flow rates corresponding to specific attachments can be programmed in the memory on the digital panel for easy retrieval for the next job.


Auto Idle
Save fuel with Kubota's Auto Idle. When the control levers are in neutral for more than 4 seconds, the engine RPM automatically idles. Move any control lever and the engine RPM immediately returns. This innovative feature reduces noise and exhaust emissions while reducing operating costs.


Load Sensing Hydraulics
You no longer need to change lever strokes to adjust the amount of oil required for varying job loads—control valves automatically regulate and distribute the optimum amount of oil to each cylinder based on the weight of the load, resulting in perfectly matched speed, power, and cylinder timing. Even the slightest operator movements produce smooth and simultaneous operation of the boom, arm, bucket and house.


3rd Line Return
When working with one-way hydraulic attachments, such as a breaker or brush cutter, the standard third-line hydraulic return system allows oil to flow directly back to the tank without running through the control valves. This contributes to less oil contamination, reduced back pressure, and greater oil flow efficiency.


The accumulator makes replacing attachments safer and more efficient. Turning the key to the "on" position clears residual pressure in the auxiliary hydraulic hose. If the engine is accidentally shut off while the front attachment is raised, turning the key to the "on" position allows you to safely lower it.


Easy open window
Contrairement à plusieurs fenêtres d'excavatrices, la fenêtre avant de la KX040-4 s'ouvre aisément. Soulevez le taquet sur la paroi de la fenêtre et glissez-la vers le haut. Un mécanisme au gaz permet d'accomplir cette opération sans effort.


New spacious cab
The KX040-4 raises the standard in 4-ton excavator comfort with a spacious cab that rivals larger excavators. The luxurious cab features a wider entrance, greater legroom and a deluxe seat. Operation is greatly enhanced with more easy-to-use features than ever before.


Anti Theft
Your KX040-4 is protected by Kubota's industry-leading anti- theft system. Only programmed keys will enable the engine to start up. Attempting to start with an un-programmed key will activate the alarm. Newly enhanced features include an alert to remind the operator to extract the key after operation, and an LED to alert potential thieves that the system is activated.


Auxiliary diverter valve
With the diverter valve on the auxiliary hydraulic circuit, the hydraulic oil can be switched to a second attachment, without having to disconnect the main attachment.
