There’s nothing compact about the KX030-4’s performance. From the rugged Kubota-built engine to the powerful digging force and simultaneous operation of the boom, arm, bucket, and swivel, the KX030-4 provides impressive performance for its size. The High-Spec model also offers AUX oil flow with proportional flow control and Auto shift for even greater versatility and performance.

AUX oil flow with proportional flow control (High-Spec model only) Thumb-operated switches provide quick and easy proportional flow control for AUX1 and AUX2.

Simultaneous operation of four functions When the simultaneous operation of the boom, arm, bucket, and swivel are required, two variable pumps will distribute an accurate amount of oil flow to each actuator according to the lever stroke. This process enables continuous high performance digging and dozing. Auto shift (High-Spec model only) 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. Powerful digging force The KX030-4 delivers an impressive bucket digging force. Its powerful and well-balanced arm and bucket allow the operator to dig fast, deep and more efficiently even in the toughest conditions. It offers power in conjunction with excellent stability.

Compact machine width The 1500 mm track width provides all the stability needed to achieve any task, while being narrow enough to operate in places where space is restricted.

1. Kubota original engine The KX030-4 is powered by Kubota’s tough and reliable engine. Engineered with the power to maximise digging and lifting performance, it also delivers minimised noise and vibration, meeting all current engine emission regulations.

2. Easy transportation Four tie down points on the upper frame help to ensure safe and convenient transportation.

Step into the biggest cab in its class and settle in for hours of comfort, convenience, and efficiency. The KX030-4’s wide and relaxing cab offers all of the functions and amenities you need to keep you working in comfort all day long, including excellent visibility, easy-open front slide window, a relaxing adjustable suspension seat, and a new forward-mounted intuitive panel for better visibility.

Easy-open front slide window

Relaxing suspension seat The KX030-4’s supremely comfortable reclining suspension seat helps you work longer with less strain and fatigue. The seat also offers weight compensation and adjustable wrist rests. Bigger cabin interior With the largest cab in its class, the KX030-4 offers a generous amount of foot space for improved comfort, as well as a tall and wide door to facilitate faster and easier entry and exit from the cab.

Unlike many excavator windows, the front glass window of the KX030-4 opens with ease. Just flip the latches on the window

sides and slide it up. A gas-assist mechanism makes this action almost effortless.

Excellent visibility To help you perform jobs more efficiently and safely, the KX030-4’s cabin offers an expansive field of vision that increases your awareness. The extra front and back visibility from the ground allows you to take on delicate tasks in tight spaces easier, and minimises the risks to people or objects. Moreover, all boom hydraulic hoses have been enclosed within the boom to reduce their damage so they can remain durable over the long term, and to enhance your field of vision so you can better concentrate on the job.

Intuitive panel Following the excellence of Kubota’s Control System, the intuitive panel puts convenience at the operator’s fingertips. The user-friendly intuitive panel is positioned to the front right corner of the operator for better visibility, and features one-touch button operation to view the time, hour meter and tachometer. Programming of the anti-theft keys can also be easily performed with the intuitive panel. With easy access, simple settings, easy-to-read indicators and alerts, you’ll always be aware of the excavator’s functioning status.

Diagnosis function The diagnosis function monitors the KX030-4’s condition and automatically alerts you in case of an emergency with warning lamps and code numbers such as for overheating, hydraulic problems or low battery.

The fully opening access door and hood provide quick and easy access to all inspection and maintenance areas of the engine. The KX030-4 is also equipped with a full range of safety features, from ROPS/OPG, to front window guard mounting points, as well as a variety of conveniences, including tie-downs and tool box.

ROPS/OPG (top guard, level I ) canopy and cabin The ROPS/OPG (Top Guard, Level I ) canopy and cabin provide protection in the event of accidental rollovers and falling objects.

Front window guard mounting points Operators who require additional protection from flying chips and debris when using some attachments or when antivandalism is important. Kubota provides the window guard mounting points around the front window as a standard feature.

Kubota Original Anti-theft System Your KX030-4 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. Its 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.

The red programming key programmes the individual keys. The individual black keys start the engine.
