Premium Performance
Hydraulic system
The WB93S-5 offers high productivity and top performance,
with increased breakout force and
lifting capacities. The core of the
Komatsu backhoe loader hydraulics
is certainly the consolidated CLSS
(Closed Load Sensing System).
Thanks to its variable flow, the
system efficiently supplies the
power the machine requires, when
it is needed. With two working
modes, “Power” and “Economy”,
the operator can choose between
maximum power and minimum fuel
consumption.
Absolute control
PPC servo-control is standard
for the front loader. The “Power
Shuttle” transmission provides the
machine with four forward and four
reverse speeds, with synchronised
mechanical shifting. The electrohydraulic differential lock, together
with the “Heavy duty” axles, increases efficiency and the operator’s confidence under any working
conditions.

Exclusive Design
Loader
S-shape backhoe
The front loader design ensures
optimal parallel lifting; in addition, the divergent shape of the
arm greatly improves visibility and
provides excellent loading performance. The design of the backhoe is
completely new: it features a clean
and functional layout, with hydraulic
piping and hoses along the boom.
The rounded shape of the backhoe
enhances the loading ability of the
machine and its capacity to overcome obstacles, while ensuring a
high breakout force. The telescopic
arm significantly increases the machine’s versatility.
5
Unique Comfort
Operator’s environment
The cab has a modern design, a
ROPS and FOPS structure and
is fully equipped. Its increased
internal volume and wide, round
glass surface optimises the ventilation system that includes several
conveniently located vents. Particular attention was given to the
internal lay-out: an easy-to-reach
control panel, ergonomic controls,
and plenty of holders and storage
compartments show Komatsu’s
dedication to provide operators
with optimal working conditions.
New seat range
The air suspended Deluxe seat or
the more traditional mechanical
suspended seat both guarantee the
best interface between the machine
and the operator. The air suspended seat also offers adjustable
armrests, headrests and lumbar
regulation as standard.
6
Total Versatility
Custom made
It’s possible to select 3 steering
modes: 2 wheel steering (standard
operation), 4WS (agile and fast operation) and crab (confined areas).
The many options offer a high level
of customisation: hydraulic sideshift for the backhoe, LSS (Load
Stabilizer System), radial tyres,
offset boom and quick couplers are
just a few.
7
Excellent Visibility
Perfect all round view
The wide round glass surface
presents a highly increased visibility. The bonnet shape and the upper
front window make it easy and safe
to work with the front loader. When
operating the backhoe excavator,
the operator can easily open the
single frame window and comfortably overlook the surrounding area.

Komatsu Satellite Monitoring System
Komtrax is a revolutionary machine tracking system designed
to save you time and money. You
can now monitor your equipment
anytime and anywhere. Use valuable machine data received via the
Komtrax web site to optimise your
maintenance planning and machine
performances.
Machine working time - With the “daily working record” chart, get precise engine running
time data: when your machine was started
and when it was shut down, as well as total
engine running time.
Fleet location - The machine list instantly
locates all your machines, even those in
other countries.
Alarm notifications - You can receive
notification of alarms both via the Komtrax
website and by e-mail.
Added security - The “engine lock” feature
allows to program when a machine’s engine
can be started. And with “geo-fence“,
Komtrax sends notification every time your
machine moves in or out of a predetermined
operating area.
With Komtrax, you can:
• Check when & where your
machines are at work
• Be informed of unauthorized
machine use or movement
• Set and receive e-mail notification
for security alarms
For further details on Komtrax,
please ask your Komatsu dealer for
the latest Komtrax brochure.
