Product Overview

Kubota's U17-3α ensures versatility and performance. Furthermore the High-Spec model delivers easier and precise operation by utilising AUX proportional flow control via a thumb switch on the joystick.

Kubota Engine

Kubota’s unique E-TVCS (Three Vortex Combustion System) enables high-energy output, low vibration and low fuel consumption, while minimising exhaust emissions.

Outstanding Travel Performance

Kubota’s U17-3α delivers powerful performance and the use of shortpitched rubber crawlers helps minimise vibration during travel for improved operator comfort.

Working Range

Kubota has designed the U17-3α to provide excellent digging depth and reach. The extended dozer length optimises the distance between the dozer and the bucket, making it fast and efficient to collect soil close to the machine. With its wide working range, the zero-tail swing U17-3α can complete a variety of jobs productively.  

Zero-tail Swing

Kubota’s zero-tail swing makes the U17-3α an advanced mini excavator. The 360° swivel, excellent stability and smooth control, combined with unmatched power and efficiency, mean there are no limits to what you can accomplish — even in heavy traffic areas and inside buildings.

Protected Front & Auxiliary Hoses

Front cylinder hoses are routed through the boom for increased protection, extended service life and greater operator visibility. Also, the auxiliary hoses extend only to the top of the arm to protect them from potential damage during narrow-width bucket use.

2-Piece Hose Design

The two-piece hose configuration on both dozer and boom cylinders reduce hose replacement time. 

Adjustable Track Gauge

For an increase in stability, the U17-3α’s tracks can be expanded to a maximum 1,240 mm. When retracted to 990 mm, you can pass through narrow doorways and tight work areas. And on both ends of the dozer, dozer blade extensions are standard.


The ultimate in security that’s as easy as turning a key. It’s the industry’s first standard-equipped anti-theft system, and another original only from Kubota.


Introducing Kubota’s simple and secure anti-theft system. Our one-key-system has an IC chip, which only starts the engine when the system recognises the appropriate key. Standard equipment includes one Red programming key, plus two Black operational keys. And up to four Black keys can be programmed. What’s more, you get peace of mind knowing your construction equipment couldn’t be in safer hands.


Only “programmed keys” will enable the engine to start. Even identically shaped keys can’t start the engine unless they are programmed. In fact, attempting to start the engine with an un-programmed key will activate the system’s alarm. This alarm will continue even after the un-programmed key is removed. It will only stop once a programmed key is inserted into the ignition and switched on to start the engine.


No special procedures needed. No PIN numbers needed. Just turn the key. Plus, our simple “one-key-security system” allows access to the cabin door and engine bonnet as well as the fuel tank.


One Red programming key and two pre-programmed Black operational keys come standard. If a Black key is misplaced, or if additional Black keys are needed (a maximum of two can be added), key programming is easy. Simply insert the Red key, followed by the Black keys.
