KUBOTA MINI-EXCAVATOR
Reaching a higher level of performance is easy
when you’ve got the most digging power in
your class. The Kubota KX71-3 mini-excavator.
Operate the KX71-3 mini-excavator’s control levers. And you’ve got the most efficient,
on-the-job performance within your hands. That’s because the KX71-3 delivers the
largest digging depth and reach of all mini-excavators with a long arm in its weight
category. Even with the long arm, it amazingly generates the largest power in its class
for both arm and bucket digging. Furthermore, the KX71-3’s lifting power is so strong.
Together with a host of robust features that complete the package, making the KX71-3
the stand-alone leader in performance.
Protected bucket cylinder hoses
Digging arm and bucket
With the ability to deliver the most digging
power, plus the efficiency of a long arm, the
KX71-3 produces the largest digging depth of all
long-arm mini-excavators*. Even with its long
arm specification, the KX71-3 amazingly
generates the biggest force for both arm and
bucket digging*. Moreover, it has the ability to
perform a wide range of tasks. (* In its class.)
To extend service life and improve
visibility, the bucket cylinder hoses are
well protected having been routed
through the arm.
Boom cylinder protector
Well protected front attachment hoses
Thanks to a V-shaped thick plate,
the boom cylinder is protected from
unexpected damage caused by the
breaker or other attachments, rocks,
being loaded onto a truck, etc.
To prevent accidental damage of the
front hoses, they are routed through the
swing bracket. Also, a metal cover plate
located at the back of the boom protects
the operator subject to a hose burst.
Variable displacement pump
For efficient operation, both the oil flow
and pressure are adjusted according
to the workload by the variable
displacement pumps. By utilizing
variable pumps a more efficient engine
is selected. This gives fuel efficiency,
low vibration and noise level.
Dozer cylinder hoses
Swing bracket bushes
To enhance durability, we’ve
adopted bushes at all fixing /
pivot points.
Utilising a more efficient twopiece design, the KX71-3’s
dozer cylinder hoses can be
quickly replaced on the spot.
Upgraded features to keep your performance up
while keeping downtime down.
Deluxe cabin
Increased rear visibility
Low noise level
To keep you operating longer, our
larger cabin delivers maximum
comfort. It provides more legroom,
an adjustable suspension seat, a
radio installation kit, plus excellent
visibility. Both cabin and canopy
offer the security of ROPS/FOPS.
The KX71-3 has a 28 % reduiced
overhang while maintaining the
same level of stability as our
conventional model. Now, KX71-3
offers increased rear visibility and
easier operation in confined areas.
When designing the KX71-3,
we kept a focus on being
environmentally and operator
friendly. Thus, the KX71-3’s
noise level in the cabin is an
amazingly low 79 dB.
Double-opening bonnet
Both daily maintenance and repairs
will become fast and easy with the
double-opening bonnet. When both
panels are opened, virtually all
components are within quick reach.
Kubota V1505-EBH engine
Safety lock system
The powerful and reliable Kubota
V1505-EBH engine provides
economical and environmentally
clean power. The engine is so
fuel efficient, a full tank gives 10
hours of continuous work.
To prevent unexpected machine
movement, the safety lever must
be raised to lock out the travel
levers and pilot controls before
the engine will start.
Kubota Intelligent Control System
An innovative upgrade that always keeps
you in tune with the KX71-3’s vital signs.
The Kubota Intelligent Control System is
equipped with warning indicators for
engine, fuel, temperature, and oil; a service
mode that enables accurate
troubleshooting; and standard indicators
which display current working conditions
such as engine rpm, hour meter, and more.

Low fuel display
2-speed travel switch
With the 2-speed travel switch re-located
from the floor to the dozer lever, you’ll
enjoy enhanced dozer operation whenever
changing travel speeds.
Wrist rest
With this new feature, to assist with smooth
operation and create less operator fatigue,
wrist rests are fitted as standard. Slight
adjustments are easy to make, plus
operation is smooth and less fatiguing.
Boom swing / Auxiliary operation
For easier operation, the boom swing
pedal and auxiliary hydraulic operations
are controled by independent pedals—with
one pedal located on the right side of the
floor and the other on the left side.
