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.

Features
 

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.

Optional hydraulic angle or 6-in-1 blade

Optional Angle Blade will 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 (optional) 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. Kubota's hydraulic 6-in-1 Blade can be angled right and left, and now, tilted as well. This blade enables six different positions: neutral, float-up, left-end-up, right-end-up, left-end-forward and right-end-forward. This feature makes leveling and backfilling work incredibly easy, even on inclines and uneven terrain, making you more productive and more efficient.

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.

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.

2-speed with auto-shift

All Kubota excavators have a two speed drive that allows for efficient machine maneuverability and backfill operations. The auto-shift system enables automatic travel shift from high to low depending on traction effort and terrain. This gives smoother operations when dozing and turning.

Auto idling system

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.

Two Pattern Selector System (TPSS)

The Two-Pattern Selection System positioned under the seat allows the operator to shift control styles conveniently while seated. A simple turn of a switch is all it takes to select between the ISO pattern and the SAE backhoe pattern.
