kubota zero-tail swing mini excavator

KUBOTA ZERO-TAIL SWING MINI EXCAVATOR
With Kubota’s advanced and upgraded U17-3α,
you’ll have the versatility and performance to
take on almost any task.
Kubota Engine
Outstanding Travel Performance
Kubota’s unique E-TVCS (Three
Vortex Combustion System) enables
high-energy output, low vibration
and low fuel consumption, while
minimising exhaust emissions.
Kubota’s U17-3αdelivers powerful
performance and the use of new
short-pitched rubber crawlers helps
minimise vibration during travel for
improved operator comfort.
Working Range
Kubota has designed the U17-3αto 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 U17-3αcan
complete a variety of jobs productively.
Buckets may vary by location.
KUBOTA ZERO-TAIL SWING MINI-EXCAVATOR
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.
990 mm
1240 mm
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.
D I G I TA L PA N E L
Informative, interactive and functional. Kubota’s Intelligent
Control System keeps you in tune of the U17-3α’s vital signs.
It accurately displays easy-to-understand diagnostics of
current working conditions and warning indicators for engine
rpm and hour meter, as well as for fuel, temperature and oil
levels. When filling up with fuel, our panel also informs the
operator that the tank is nearly full, and alerts the operator to
when routine maintenance is due. Overall, the panel reduces
excavator repair time for a decrease in total operating costs.

ROPS/FOPS Canopy
Safety first. The canopy
conforms to ROPS (RollOver Protective Structure)
and FOPS (Falling Objects
Protective Structure) Level
1 specifications, so that you
can concentrate on what’s
important — your work.
2-Speed Travel Switch on
Dozer Lever
Straight Travel
The dozer lever features a
2-speed travel switch, which
allows the operator to easily
select between power or travel
speed during levelling work,
depending on the load.
Loading and unloading
is safer due to a unique
Kubota hydraulic system
that provides straight
travel, even during
simultaneous operations.
Long arm version
Reach further. Dig deeper. Extend your working range,
increase your productivity and expand the kinds of jobs
you can undertake with the U17-3α’s long arm version.
At an impressive 1100 mm, a full 150 mm longer than
the standard arm version, the long arm version offers a
surprising reach for an excavator this size. Kubota has
also optimized the excavator's weight to ensure reliably
stable operation.
Boom Cylinder
The boom cylinder is situated
above the boom for maximum
protection, especially during
breaker or dumping operation.
Movement speeds of front
attachments and lifting power have
been well adjusted, thanks to the
boom cylinder’s large-diameter rod
and optimal hydraulic pressure.
Protected Motor Hoses
Kubota has enclosed the travel
motor hoses within the track
frame for added protection—
a unique feature for mini
excavators of this class.
Easy Maintenance
When maintenance is simple, downtime is greatly reduced
and you’re more productive. With the U17-3α, routine
maintenance is easy—the rear bonnet, side covers and
the under-seat cover open up without the need for tools.
This allows for quick access to the engine oil gauge,
radiator, battery, air and fuel filters, and much more.
Accessing the under-deck hydraulics is also fast and
easy, because there aren’t any bolts to unscrew—just lift
the rubber mat and open the floor plate. Plus, for extra
strength and easier repairs, the U17-3α’s bonnet and side
covers are made of steel.
Front Bush Pins
For increased durability, Kubota
has included bushings throughout
the U17-3α’s pivot points on the
swing bracket, as well as critical
jointed points. And if necessary, the
bushings can be easily replaced.
A N T I -T H E F T S Y S T E M
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.
THE SYSTEM
SAFETY/SECURITY
Introducing Kubota’s new 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.
EASY OPERATION
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.
EASY PROGRAMMING
N special procedures needed. No PIN numbers needed.
No
JJust turn the key. Plus, our simple “one-key-security
system” allows access to the cabin door and engine
sy
bonnet as well as the fuel tank.
b
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.
