2021 Kubota KX040 Series 4G

The Kubota KX040-4 combines superior strength, versatility and performance to deliver one of the most balanced mini-excavators on the market. Incorporating industry leading technology, the Kubota KX040-4 produces less noise, reduced emissions and is equipped with eco mode, which can generate fuel savings by up to 20%. Now with an angle blade model in the lineup the Kubota KX040-4 sets the benchmark for all other mini-excavators to follow.

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.

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.

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.

Features may include:

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.

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.

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.
