CONTENTS
Towards new goals
Last year was a really good year. Market demand was strong, especially in
the first half of the year and sales went
well and we increased our market share. When we summarize 2011, I can
say that we exceeded all goals while
at the same time we carried out both
quality and production improvements.
Right now, however, the market
is in a recession again since the latter half of 2011. The macro-economic
uncertainty in Europe is settling in and
starting to affect the global market.
Weak demand is predicted to continue during the first half of 2012, however in the second half, we expect
the economy to recover and market
demand will increase.
Despite the current recession giving a feeling of a downturn, especially in Europe, we are determined to set
new strategies with challenging goals.
Where we will concentrate even more
focus and resources on product development and quality improvement.
Right now we are launching
two new medium-sized forwarders
Komatsu 855 and Komatsu 865 following the introduction of the harvesters
with a new E3-power engine. The new
forwarder models will have a completely newly designed cab, new transmission system, MaxiXplorer and E3power engines. E3-power has been
proven to be a success, offering far
less fuel consumption and lower noise
levels on harvesters.
Another focus area has been to
strengthen the aftermarket with the
help of ICT systems (Information and
Communication Technology). The first
step was the introduction of the MaxiFleet system that enables our customers to improve work efficiency and
for us to improve our own service and
support to our customers. Those who
will initially benefit from the great advantages are customers with a large
fleet of machinery, such as companies
working in plantations. I also believe
that individual machine owners will
quickly realize the usefulness of the
new opportunities to monitor machine
operation.
Scandinavia and rest of Europe
have always been important markets,
but we have also been successful in
markets such as Brazil, Russia and
Indonesia. All in all, all the Komatsu
Group is working to support the forest
sector in many countries around the
world and we are the Komatsu specialists in forestry and our successes
in 2011 show, that Komatsu is now regarded as a reliable partner with solutions for the global forest sector.

THE KOMATSU 855 AND THE KOMATSU 865 are ideal forwarders for everything
teristics, but unmatched combustion efficiency, which results in low fuel consumption. A new transmission system that adapts
to loads, inclines, and obstacles also helps
make the Komatsu 855 and the Komatsu
865 productive forwarders. The hydrostatic transmission system and diesel engine’s
characteristics are optimized with each other to provide maximum traction. With really
good traction it is now possible to increase
the driving speed, even when the terrain is
challenging.
THE NEW FORWARDERS also boast a
brand new cab that is larger in all directions.
What’s more, upward and side visibility have
been improved. The seat is ergonomically
designed and specially developed for forest
machines. Add to this many new details that
make life in the cab more comfortable and
the result is a world-class cab environment.
The MaxiXplorer 3.0 control system ensures that the Komatsu 855 and the Komatsu 865 have the market’s best status and
production reports.
from thinning assignments to final logging,
and with two effective medium class forwarders you can now choose the one most
suited to the conditions of the job.
The load capacity of the new forwarders
is 13 metric tons (14.3 tons) and 15 metric
tons (16.5 tons) respectively, and with the
new green E3-Power engine these new forwarders are both powerful and nimble. The
new engines in the forwarders not only offer
high performance and good engine charac-

Naturally, a forwarder shall
ensure that the timber

the shortest time possible
and with the best possible
comfort for the operator.
Driving shall be fast,
responsive, and easily
handle any difficult terrain.
The Komatsu 855 and the Komatsu 865
have a completely new transmission system
with characteristics such as automatically
adapting to loads, slopes, and any obstacles in the forest. Everything to make them
as productive as possible.
The Komatsu 855 and the Komatsu 865
move quickly and nimbly through the forest,
regardless of the terrain. The forwarders’
new hydrostatic transmission system and
the characteristics of the new diesel engine
are optimized to jointly provide maximum
traction. This means that the system automatically adapts the traction and provides
high torque at low engine speeds.
In the Komatsu 855 and the Komatsu 865,
the operator controls the infinitely variable
transmission speed range for both high and
low gear. The system automatically adapts
when the load changes depending on the
terrain, obstacles, slopes, and crane loads.
The handling can also be changed using
different driving modes depending on the
operator’s preferences. There is, for example, a driving mode for optimum fuel efficiency.
To make even better use of the diesel
engine’s performance and to improve the
new forwarders’ handling in steep terrain,
the transmission can further increase traction when the going gets tough and speed
is low. This enables the forwarders to pass
over obstacles considerably easier compared to machines with the previous generation of hydrostatic transmission systems
(see chart and illustration at top of page).

HIGHER PERFORMANCE
Fuel economy and environmental requirements drive
development in forest machine engines. With their
new engines, the Komatsu 855 and the Komatsu 865
guarantee more effective combustion, more favorable
fuel economy, and compliance with strict environmental
requirements. What’s more, the new engine offers higher
performance than previous engines.
8 +645'03&45/0t
The engine concept used in the new forwarders is called E3-Power, standing for
Environmental, Economical, and Efficient.
Three prerequisites for an engine that is
good for the environment and its owner.
THE KOMATSU 865 has a powerful
7.4-liter engine that is strong enough to
cope with anything. The Komatsu 855 has
a powerful 6.6-liter engine with an engine
curve that copes very well with heavy loads and reduced engine speeds. The forwarders’ new engine uses well-proven
common rail technology with even higher

injection pressure and more exact injection.
With a new injection controller, injection is
both faster and more exact, which provides
greater engine power, higher torque, lower
emissions, and lower fuel consumption.
Add to this the fact that the new engine has
optimized combustion chambers and the
result is an engine with the most effective
combustion when power is most needed. A
wastegate valve makes the engine responsive even at low engine speeds. The engine
even has a new fan belt for improved reliability and less maintenance.
WITH THE MORE EFFECTIVE combustion offered by the new engine, particulates
have been reduced to a minimum. However,
in order to fulfill environmental requirements
in Europe and North America, nitrogen oxide
emissions must also be reduced. In areas
where environmental requirements have
been introduced, the new engine is equipped with an emission control system known
as SCR, or Selective Catalytic Reduction.
SCR technology is well proven in the truck
industry, with most major manufacturers
already employing the technique. An emis-
sions control system with SCR technology
works by injecting a urea solution into the
exhaust gases before they pass through the
catalytic converter. Once inside the catalytic converter, the urea solution reacts with
the nitrogen oxides in the exhaust gases,
forming mostly water and nitrogen gas. The
additive, called DEF (Diesel Exhaust Fluid), is
comprised of a mixture of urea and distilled
water. It is safe to handle and does not harm
the environment. The DEF is stored in a separate tank near the diesel tank and is easily
topped up when the machine is refueled.

OPERATOR ENVIRONMENT
MOST IMPORTANT
10 +645'03&45/0t
Everyone knows that the operator environment is of the
utmost importance if an operator is to cope with the
demands of working in the forest. Ergonomics, space,
air quality, and vibrations are important factors that affect
the operator environment. All of these aspects have been
improved in the new Komatsu 855 and 865 forwarders.
When viewing the new Komatsu 855 and
Komatsu 865 forwarders from the outside,
it’s clear that the cab has a completely
new design with a stronger structure. This
means a larger interior for the operator in
all directions. Compared to the previous
forwarder cab, the interior volume has increased by 21 percent and the cab is both
taller and wider. Legroom is also improved.

out during breaks.
THE NEW FORWARDERS also have
greatly improved visibility. With larger windows throughout, the cab offers better allround visibility. Since the cab is taller, and
the design refined, upward visibility is substantially improved. Side visibility is also im12 +645'03&45/0t

designed seat developed specially for forest machines. Using user-friendly electric
controls, the operator can quickly adjust the
seat to achieve the best possible work posi-
tion – and the seat can also be locked at any
angle between 0-220 degrees.
The operator environment in the new
forwarders has been refined with more and
improved storages spaces, placed in wellconsidered locations and offering useful
functionality. The cabs feature generous
storage spaces and well utilized surfaces.

A NEW SMART RADIO is a comfort requested by operators. The new smart radio
has Bluetooth and handsfree support, for
example. This makes it easy to wirelessly
connect a smartphone to the radio, such as
to stream music or audio books. If the phone rings, the radio automatically fades so
the operator can answer using the handsfree function.
THE WORK ENVIRONMENT IN THE
KOMATSU 855 and the Komatsu 865 provi-
des a quieter experience than previous for-
warders. This is due to, for example, openings into the cab, such as for cables, being
fitted with seals to prevent open channels
for noise. A noise shield is now also fitted
between the engine and the cab to prevent
engine noise propagating into the cab. Added to this is the more pleasant sound of the
new engine and a fan controller that automatically regulates the speed of the cooling
fan according to oil cooling needs. With a
new integrated air filter the quality of the air
purification has also improved.
When working in the dark, good work
lighting is essential to work effectively. The
new forwarders have up to ten well-integrated and protected work lights and completely new articulated joint lighting. The work
lighting can be controlled via Maxi using
preset modes, such as full work lights, roadside, transport, and service settings. The
interior lighting has also been improved with
integrated spotlights, floor lighting, and a
map reading light.

THE MOST MODERN
CONTROL SYSTEM
ON THE MARKET
The brains of the new
Komatsu 855 and Komatsu
865 forwarders are found in
MaxiXplorer 3.0, which is one
of the most modern control
systems on the market and
is already found in Komatsu
harvesters.
14 +645'03&45/0t
MaxiXplorer 3.0 is a fully integrated machine
control and reporting system that communicates with the operator in a user-friendly
manner. This involves, for example, providing the operator with functions for controlling the engine, transmission, and crane,
thereby maximizing the new forwarders’
productivity.
The forwarders’ machine control and reporting system includes new hardware and
new software. The new control levers in the
Komatsu 865 and the Komatsu 855 are called Komatsu Comfort Controls. The Komatsu Comfort Controls have a new ergonomic
design and are now integral with the seat
armrest. The keypad has several new buttons that are easily accessed. The functions
of the buttons can be set individually. Backlighting makes it easier to see the buttons in
the dark and the backlight is automatically
adjusted to the brightness of the cab.

CUSTOMERS DETERMINE
DEVELOPMENT
A good machine must
fulfill customer needs.
Consequently, users
have been an important
source of information in the
development of the new
forwarders.
In the development of the Komatsu 855 and
the Komatsu 865, user opinions have provided decisive information. In addition to all
the important information gathered, for example, from sales and service organizations
around the world, customer surveys comprise a valuable tool.
Prior to the development of the new for-
warders, operators from several parts of the
world were surveyed. And not just Komatsu
operators, but even operators of other competing brands. Their opinions were gathered
with the aid of comprehensive interviews
and the results of the operators’ opinions
are clearly seen in the new Komatsu 855
and Komatsu 865 forwarders.
Lower fuel consumption was at the top of
the wish lists received from many machine
owners, and the new engine is guaranteed
to deliver better fuel economy. Naturally, for
the operators the cab environment is important, and several improvements reflect
the operators’ input. More space, better
visibility, lower noise level, more storage
compartments, ergonomic seat, better lighting, and extra features to make daily life
more comfortable.

COOPERATION IS
IMPORTANT FOR
DAVE AND IAN
Dave and Ian Nuttall, of
Monaro Logging on
Australia’s south-east coast,
are firm believers that good
machines and good people
to deal with are key points
in the forestry business.
16 +645'03&45/0t
Dave, now the self-professed ‘overseer’ and
son Ian (director) have had a long and highly
successful tie with Komatsu and they say
it’s not just the machines but it’s the relationships that are crucial.
Dave has been in the game more than
three decades after having had his start in
New Zealand.
He can’t quite remember the model of
the first Komatsu he bought but he readily
talks about his latest purchases … five new
forwarders (all eight-wheel 890.3s) and
two new harvesters (PC400 & XT450L).
“That means we’ve now got 10 Komatsu
forwarders and six Komatsu harvesters.
Obviously the work rate of the machines
speaks for itself,” he says. Incidentally, just
after changing the company name to Monaro Logging back in 2001 one of the first
Komatsus ordered was an 890.1.
“As I said, it’s not just the machines. It’s
a combination of good units plus the close relationships built up with everyone at
Komatsu Forest.
“We have had a very professional relationship with Komatsu Forest and always
had good backup and always had a good relationship with everybody concerned, really.”
“We have had a good a good run with the
machines,” says Ian, “but it’s not all about
MONARO LOGGING harvests about
Dave and Ian Nuttall from Monaro Logging
the machines though, it’s the relationships
that go with the backup.”
Dave says his operators are well pleased
with the Komatsu 450 with the 23 inch
Waratah head. “It’s a good, well-balanced
machine,” he says, “and they seem quite
comfortable getting the best out of it.”
HE WAS ALSO HIGH IN PRAISE of the
new forwarders and said they were well and
truly living up to expectations.
And he’s looking forward to the commissioning of a new 40-tonne harvester with a
25 inch head (probably the first in Australia).
“That’s happening soon and it should really
be something,” said Dave.
MONARO LOGGING currently employs
65 (including mechanics and office and administration staff) and carries out most of its
work in pine in the Tumut area and also in
the Bombala region working under contract
for Forests NSW.

ENGINE TECHNOLOGY
DEVELOPMENT
AN ENGINE
FOR THE
FOREST
The engine is the heart that
provides forest machines
with their power.
Development is constantly
moving toward stronger
engines with lower fuel
consumption, specially
adapted to the conditions of
the forest. Now the engines
even fulfill all strict
environmental requirements.
THE LATEST GENERATION OF ENGINES
for wheeled machines combines three good
things. High performance, high torque, and
low fuel consumption. What’s more, it also
fulfills the European and American emission
requirements of Tier 4i/Stage IIIB.
The fuel injection system is central to
all diesel engines and throughout the entire history of the diesel engine efforts have
been made to achieve increasingly higher
injection pressure. The engines have long
had the common rail injection system,
which means only a single common fuel line
is used for all cylinders.
The latest generation of common rail systems has a higher injection pressure than
18 +645'03&45/0t
ever, more accurate timing, and more effective air charge cooling. Three important factors that provide a strong engine, rapid engine response, high torque, low emissions,
and – not least – low fuel consumption.
A NEW GENERATION of computerized
and electronically-controlled fuel injection
systems with even higher injection pressure
enables the engine to respond immediately
without delay to changes in load and the
electronic injection system optimizes the
pressure regardless of operating conditions. The result is engines with faster response than ever and since new electronic
fuel injectors make it possible to inject the
fuel seven times per injection phase, combustion is also more even.
THE ENGINES HAVE FOUR valves
per cylinder, two inlet valves and two outlet valves. This design enables the fuel injector to be placed in the middle, between
the exhaust and injection valves. With two
inlet valves and two outlet valves, the fuel
flow can be increased and pump losses reduced. This improves the air/fuel mixture,
which results in lower emissions and – more
importantly – lower fuel consumption.
The fuel injection system also has electronic pre-injection, which means a considerable reduction in engine noise and
vibrations. Moreover, the slow increase
in combustion pressure results in lower
engine noise, with the typical diesel engine
sound almost no longer heard. The sound of
the combustion is even and the frequency
pleasantly low.
Naturally, good torque at low engine
speeds is important for both harvesters and
forwarders. The engines are specially developed to cope with the conditions of the
forest and as such produce high torque at
low engine speeds. What’s more, the torque
rises quickly. The result is a machine that always works effectively, while fuel consumption is low.
The engines are even highly reliable and
easy to maintain. An important detail for
reliability is wet cylinder liners and the air
charge cooling, which extend the engine’s
service life and reduce operating costs. Wet
cylinder liners provide better cooling and
more even temperature distribution.
THE ENTIRE FUEL SYSTEM is found
on the cold side of the engine and the fuel
filters are easily accessed and quickly replaced without any tools. All service points
on the engines are easily accessed for quick
and effective service.
EMISSION CONTROL WITH SCR
WHEN IT COMES to emission control tech-
nology the trend is clear, even if there are
two different emission control techniques
to choose between, SCR and CEGR. Most
truck manufacturers have already chosen
the SCR technology (Selective Catalytic
Reduction), which is considered ‘future
technology today’, and now the majority of
forest machine manufacturers have made
the same choice.
In the EU and the USA emissions of NOx
and particulates from forest machines are to
be gradually reduced leading up to 2014. The
serious nature of the legislation is seen in the
rapid rate of reduction – from a 29 percent
NOx reduction and a 10 percent PM reduction in 1996 to a full 97 percent reduction of
both NOx and PM by 2014 (see illustration).
THE MAIN ADVANTAGE of SCR technology is that one can simultaneously fulfill
the strict emission requirements and reduce
fuel consumption. SCR is an emission control technology with which particulates are
reduced during combustion while NOx is
reduced afterward outside of the combustion process. SCR technology enables the
combustion process to be optimized, which
guarantees both maximum engine performance and lower fuel consumption. What’s
more, the engine is less sensitive to lower
quality diesel compared to engines equipped with CEGR.
NOX REDUCTION takes place after
combustion through the use of a urea solution (DEF, Diesel Exhaust Fluid) and a
catalytic converter. In an electronically
controlled process the DEF is injected into
the exhaust system just before the catalytic
converter. When the mixture of exhaust gases and DEF passes through the catalytic
converter, the nitrogen oxides are converted into harmless nitrogen and water vapor.

Emission legislation in the EU and the USA regulates a systematic increase in
emission control to cut emissions of NOx and particulate matter (PM) leading
up to 2014. The rate of reduction is rapid – from a 29% NOx reduction and a 10%
PM reduction in 1996 to a full 97% reduction of both NOx and PM by 2014 (see
illustration). However, the rate at which emission legislation is being tightened varies
in different parts of the world. Stage 4/Tier 4 Final encompasses Europe and North
America, although in the longer term the same requirements will most likely apply in
most of the world.

DEF is essential for SCR technology to
work. Without it, engine power is reduced to ensure that emission requirements are met. The easiest way to ensure that you always have DEF is to top up
the DEF whenever you refuel. The DEF
should comply with ISO standards and
be of good quality.
DEF can be bought in containers or in
various bulk systems. DEF consumption
typically ranges between 3-5% of diesel
used.

PRESENTATION: MaxiFleet
Imagine how you as a machine owner could
follow your machines on a screen in the same
way you can follow stock prices. With a broad
overview you can easily see how production is
progressing and where your machines are. And
all without the operator needing to lift a finger for
the information to flow.
MAXIFLEET:
EFFICIENCY IN
THREE DIMENSIONS
MaxiFleet is a completely new system for
the forest industry that makes it easy to
keep track of your machines in almost real
time. MaxiFleet enables you to quickly see
where all your machines are, to follow production and operation, and to provide remote support. MaxiFleet makes work more
effective regardless of whether you have
just a handful or many machines, whether
you’re an operator or a machine owner.
MAXIFLEET AUTOMATICALLY manages the information flow from the forest
machines. With secure direct access to every single forest machine, you can remotely
20 +645'03&45/0t
collect the information you need instantly.
Communication to and from the machines
travels via the regular cell phone network or
high-speed satellite. You can retrieve the information using a regular web browser or an
app in your smartphone.
A MAJOR ADVANTAGE of MaxiFleet
is that operators need not consider administration and can instead fully concentrate
on production. The system ensures, for
example, that files are automatically received and that production, GIS, and machine
status data are sent without involving the
operator. MaxiFleet also provides almost
unlimited opportunities under the StanForD
standard to tailor custom reports using the
data automatically sent from the machine.
With the system’s report tool you can create
reports of your own design and save the
settings as a template. This makes it easy
to select a template, specify a time interval,
and create the report you want. The tool
also makes it easy to create summaries
of defined time periods – weekly, monthly,
quarterly, annually – for the entire machine
fleet. The reports are always available in a
list and can also be presented graphically
in pie or bar (horizontal and vertical) charts.

Reports can also be used to compare, for

THE MAP FUNCTION provides economic and satellite maps from all over the
world.
Work with the machines’ service and
maintenance is also considerably simplified with MaxiFleet as all information can be
used to prevent problems and plan service
and maintenance or to analyze the need to
change machine settings. This reduces the
risk of unplanned disruptions to production. Thanks to the opportunity for two-way
communication with the machines, it’s also
possible to remotely change machine settings, which contributes to more effective
production.
MaxiFleet normally sends data via the
cell phone network available in most areas
where forest machines are used. In markets
where the cell phone network offers insufficient coverage outside of urban areas, such
as in Brazil, the data is sent via high-speed
satellite instead.
TECHNICAL FACTS:
MAXIFLEET
Communication to and from the
machines goes via either the cell phone network, such as 3G, CDMA, and
UMTS900, or satellite, depending on
the country. Several forest machines
can form an internal network by creating what is called a mesh network.
All information from the machines is
available via the Internet or a smartphone.

AFTER
THE STORM
Three years after the storm
designated Klaus ravaged
the French region of
Aquitaine, Jean-Louis
Dupouy has resumed
logging the forest that
escaped devastation.
22 +645'03&45/0t
The company Dupouy Freres, based in
Soustons in the southwestern part of the
Department of Landes, has two harvesters,
a 921C and a 941.1, and two forwarders,
one of which is a Komatsu 860.4 delivered
in June 2011.
TRADITIONALLY, THE company, in
which Jean-Louis is part of management,
has worked for a local sawmill conducting
final logging.
The storm Klaus entailed extensive work
taking care of windthrown timber and JeanLouis was kept more than busy operating
the 941.1, which was delivered in May 2009.
THANKS TO THE 370E harvesting
head, the broadest timber – already felled
by Klaus – was processed and delivered to
sawmills or watered log piles. The powerful unit formed by the harvesting head and
crane has proved invaluable in dealing with
the windthrown timber, as well as for trees
infested with bark beetles. In the summer of
2010, an entire forest stand in Landes na-
mely suffered a major invasion of bark beetles, and the infected timber needed to be
dealt with quickly.
In 2011 the company bought a new forwarder – a Komatsu 860.4 – to replace an
old 860 and could easily take care of the
timber logged by Jean-Louis. In this way,
they’ve been able to secure a much higher
timber supply for the sawmill.
TODAY THE URGENCY has passed and
Dupouy Freres has resumed logging the
forest acquired before the storm hit. With
a somewhat calmer tempo at work, JeanLouis can spend more time on his hobbies:
hunting woodcock and pigeon, and sea
fishing. Otherwise, Jean-Louis also regularly plays a typical local sport: Basque pelota.
It’s reminiscent of squash, but played by
two teams with two players on each team.
This is how an entrepreneur from Landes
brightens his day.
Operator Michel Messa has once again been given the opportunity to drive
a red machine.
THE RETURN OF THE ”REDS”
Sebso is a company
based in Saint Gaudens
in the Pyrenees.
The company works
throughout a large part
of southern France, and
as early as 1992 – when
mechanization first took
seed in France – bought
six 901 harvesters.
At that time, Sebso’s primary role was to
supply the paper pulp industry in Tarascon
and Saint Gaudens with timber, now operations have broadened and currently encompass all types of forestry.
TODAY THE COMPANY owns six harvesters, four of which are red. The latest
acquisition is a Komatsu 911.4 with the new
365 harvesting head, for work in the alpine
pine forests.
Operator Michel Messa has extensive
experience of operating harvesters; he started out in 1995 with a 901 harvester. Since then, he’s operated two other types of
machine, most recently a tracked machine
for harvesting on steep slopes.
RETURNING TO a Komatsu has been
a positive experience for Michel as the harvester, equipped with chains and tracks, has
coped with work on the same slopes just as
well, thanks to the new Komatsu Comfort
Bogie. Michel appreciates the speed and
power of the 365 harvesting head, which
takes care of the pine with the best possible
productivity. The low noise level, like the
machine’s general ergonomics, enable Michel to concentrate on processing, so that
the logging work fulfills the environmental
standards that Sebso aims for.
Jean-Louis Marsande, who is responsible for harvesting and supervises the work
conducted by all machines, emphasizes the
low operating costs for Komatsu harvesters and is pleased to see the return of the
“reds” to his fleet.

BETTER
AND BETTER
In a continually changing world, user needs are continually
changing. As such, it’s important to continually improve our
products so as to always be able to offer the most
effective machines.
Ground-breaking changes often coincide
with new models and new products, but
between such launches, work is always underway to continually improve things. This
work is based on the ideas of the Kaizen
concept, which is Japanese, with Kai meaning change and Zen meaning continual improvement.
MOST OF THE improvements are made
in consultation with customers and the fo24 +645'03&45/0t
cus is always on the customer. The idea is
to give the customer what they really want
and need.
Often this entails many small improvements, which together make the products
better. Some improvements provide a certain model with specific characteristics;
others are more general and improve the
quality of all machines.
HUNDREDS OF SUCH small improve-
ments are made between the launches of
one new product or model and the next.
Here are a few of the many improvements
we’ve made to our forwarders, harvesters,
and harvesting heads this past year.

THE PERFECT TOOL
FOR A MASTER
OPERATOR
The people who know the
machines best are often the
operators. They know with
which machine they are
most productive. As a
machine owner, having the
right machine can be as
important as having good
operators. When Timo
Tiainen bought a Komatsu
901TX.1, master operator
Kyösti Paavilainen was back
to his old self.
26 +645'03&45/0t
Timo Tiainen’s 901TX.1, which has clocked
up just over 100 hours, thins young spruce.
Right now he’s pretty happy, having just employed Kyösti Paavilainen, one of Finland’s
most qualified forest machine operators.
However, generally he’s worried about the
availability of forest machine operators. How
are you to attract skilled youths to train to be
forest machine operators and how are you
to get good operators to remain in the industry when work conditions are sometimes
problematic and other industries seem more
attractive? Finding good operators is a problem throughout Scandinavia. What’s more,
the machine owners’ margins are often so
small that they can’t afford to train new operators, so for a while they produce less.
”When youths train to be machine opera-
tors, internships at contractors often seem
promising, but then they choose not to follow the forest machine operator career path
despite a promise of guaranteed work. Instead they drive trucks or excavators,” says
Timo, who has five employees.
Forest machine contractor Timo Tiainen
lives in a region that is said to be the most
beautiful in Finland. In the winter, Saimen’s
beautiful archipelago is covered in snow
and ice, and some of the traffic moves from
the regular roads to ice roads, which shorten journeys by tens of miles in this landscape of splintered waterways.
A few miles east of the city of Nyslott runs
an ice road that offers the shortest possible
route to the workplace where Timo’s new
Komatsu 901TX.1 is placed.
These are the kind of conditions for which the new
thinning expert, the Komatsu 901TX.1, is made.
Two satis
fie
First we follow Timo a few miles on land,
then the road turns unexpectedly out onto
the ice, where a staked-out route opens to
the southeast. Sometimes the road runs
along the shore.
Timo’s path to becoming a contractor
is the most common. As soon as he left
school he started forwarding timber with
his father. The first site he worked on would
have scared many people back to school,
but Timo didn’t find it scary each morning
when he brought the frozen machine back
to life and drove the mile from the forest to
the clearing.
”My father and I logged alder trees. To
our aid we had an agricultural tractor and a
sled with a crane winch, which we used to
more easily lift the alder bundles onto the
d m e n: c o
ntractor

inen (righ
sled. At the shore we unloaded them and
piled them up by hand,” he tells.
Now there’s tough competition for professional operators. When Timo heard that
Finland’s foremost operator, Kyösti Paavilainen, was available, it was high time to make
a move. With medals from five Finnish and
one European forest machine championships he’s one of the most qualified operators in the industry. Timo already knew of
Kyösti because Kyösti has perfected his
skills at Timo’s workplaces in preparation
for competitions.
This past fall Kyösti started working for
Timo. Everything went well, but as an eagleeyed employer Timo soon noticed that something wasn’t right. Kyösti wanted a red
machine to be the truly productive opera-

ilainen.
tor he’s proven himself to be. At first, Timo
looked for a relatively new used Komatsu,
but soon decided to buy a brand new
Komatsu 901TX.1 with the new E3-Power
engine.
”The full-circle slewing and leveling cab
is superior if you want to be truly productive,” notes Kyösti.
Timo’s 901TX.1 has proven to be a true
thinning expert in the young spruce forests
the harvester has worked in so far.
”It’s power, maneuverability, and reach
make it a true specialist for thinning and
lighter final logging. Profitability is now no
longer down to the machine,” says Kyösti.

The floor of the test rig is specially
designed to handle the high loads
The frame is loaded with the right weight
and the entire test is monitored from the
adjacent control room.
The new test method condenses the time
taken for testing, which will be of great
significance to the speed of product
development and the opportunities to
quality assure products.
INVESTMENT TAKES TES
A new test center is taking forest machine quality
assurance to a completely new level. Testing a machine’s
entire life cycle now takes little more than a month. This is
a quality assurance initiative that will be of great importance
to our future product development and quality assurance
work.
28 +645'03&45/0t
THE INVESTMENT IN the new test center
is yet another step in the development of
our systematic quality assurance work. The
new test center is adjacent to the plant in
Umeå and the premises have been specially designed with the help of the experience
of Komatsu Ltd. The new center enables
structured bench testing of larger welded
constructions, such as entire forest machine frames.
THE TEST METHOD HAS adopted its
basic features from Komatsu Ltd, which has
worked with this type of quality assurance
for more than 30 years, making it well pro-
ESTING TO NEW LEVEL
ven, with adjustments for its use with forest
machines. In simple terms, we can say that
the stress to which a machine is exposed
during a period of five years in the forest is
now brought into play more exactly, and in
the exact same way, in a fraction of the time,
which will provide a considerably better verified end product. This laboratory environment is used to test all larger welded constructions, such as frames and cranes, and
now even other components. The new tests
also make it possible to work even more effectively with suppliers, and after testing we
can further improve our knowledge in the
field and achieve even better quality assurance.
THE TESTS IN THE NEW test center
are based on real world values from the field
that are condensed and brought to bear on
the components in a laboratory environment, which means that quality assurance can
be conducted much earlier in the product
development process.
Traditional tests and measurements in
the field have shortcomings since they take
a long time to conduct and are performed
under very different conditions. The ability
to perform condensed quality assurance
tests in a laboratory environment takes testing in the forest machine industry to a level
that wasn’t previously possible to achieve
with field tests.
This is not only significant for the ability
to conduct risk and safety tests, but also
for all stages of product development. The
condensed test period means that product
development can be both bolder and faster when it comes to realizing new design
ideas.

7,000 harvesting heads delivered over a little more than 25 years
makes Komatsu one of the largest harvesting head suppliers. That
which began with tentative trials with Valmet single-grip processors
as early as the 1980s is now the prevailing method for delimbing
trees. Over the years, top selling models such as the 942, the 960,
the 965, the 350, the 360, and the 370 – all in a number of variants
– have been delivered to customers. Today, there is a harvesting
head for most assignments and machine applications – everything
