901TX.1

The Komatsu 901TX.1 is the new version of our market-leading thinning harvester. With new technologies and our inherent design advantages, Komatsu now provides an unmatched combination of production, low environmental impact and economical operation in a thinning harvester. Here are a few of the essential new features and benefits:

Economic operationHigh reliability, simplified

maintenance and low fuel

consumption provide a very

manageable cost of ownership.

HandlingKomatsu Comfort Bogies deliver a

smooth ride while providing superb

mobility and maneuverability.

New engineNew powerful engine that minimizes

NOx emissions (nitrogen oxides) and

provides exceptional fuel economy.

Ground clearanceHigh ground clearance, 635 mm

(25”) enhances mobility while

reducing the machine’s impact in

the forest.

Operator environmentGenerously sized cab, large win-

dows and the ideal relation of the

side-mounted crane creates a high

performance work environment.

HydraulicsORFS couplings on critical hydraulic

components create tight seals which

minimize the potential for leaks

reducing down time and protecting

the environment.

MAXIMUM PERFORMANCE AND FUEL EFFICIENT.

Tomorrow’s engine today Unbeatable fuel economy.

Minimized environmental impact.

Lower service costs. Less engine

noise. These advantages are

thanks to the new SCR engine

developed with our E3-Power

technology.

Powerful and

fast crane

options, 10 m

(32.8’) and 11

m (36’) provide

ideal reach and

handling charac-

teristics.

Information system The MaxiXplorer information

system offers the market’s most

comprehensive machine control,

as well as status and production

reports.

Bogie to provide superb mobility

and maneuverability.

How do you improve a thinning machine

that is already considered the most ef-

ficient and environmentally friendly in the

world? The answer is the new Komatsu

901TX.1, which delivers additional green

and economic benefits. The explanation

is the completely new SCR-based engine,

which dramatically reduces both emis-

sions and fuel consumption.

And it doesn’t end with emissions well

below legal requirements and world-

leading fuel economy! With our E3-Power

technology, operating costs are further re-

duced thanks to a number of factors from

control systems that ensure operation

through long service intervals to cleaner

engine oil. A new feature improving ser-

viceability is that all critical hydraulics use

ORFS couplings, which reduce the risk

of leaks. Another important part of this

Cab and crane

leveling and

stabilizer coupling

for optimum reach

and stability. Crane

placement close to

the cab ensures that

the head is always

directly in front of

you. Extremely pro-

ductive for thinning.

to the full-circle

slewing platform.

machine’s cost efficiency comprises the

detailed status and production reports

from the powerful MaxiXplorer computer

system.

The proven characteristics of the

901TX.1 include the optimal combination

of high productivity and low environmen-

tal impact. A considerable factor in this is

the crane, which is one of the strongest

on the market and provides an advantage

when working at long reaches. Add to this

the low total weight, high ground clear-

ance, and fantastic maneuverability, and

you soon realize that no other thinning

harvester gets as much done with so little

impact on the forest floor and surround-

ing forest.

Similarly, the 901TX.1 combines human

efficiency and ergonomics. The cab is an

extremely high performance operating

environment with generous proportions

and large surround windows. The relation

of the side-mounted crane to the full-circle

slewing and leveling cab also maximizes

operator visibility. Choose the Komatsu

901TX.1, with either 6 or 4 wheels, for

optimal thinning profitability. The kind of

profitability modern forestry demands.

WHY CHOOSE A KOMATSU HARVESTER?High productivity, low operating costs, innovative technology, superb operator environment – these are

just some of the features that make Komatsu forestry machines some of the best in the world. Behind all

this is a highly-focused strategy to continually build upon the advantages of owning a Komatsu harvester.

A strategy based on the following principal ideas.

ErgonomicsYour forestry equipment and its mobile work environment

is critical to an operators ability to maximize production

without fatigue and is a key factor for success. This is an

important reference point used in developing the unique

egronomic designs of Komatsu harvesters. Automatic

leveling cabs, side mounted booms and large operator

compartments work together to keep the harvesting head

centered in the operators field of vision.

EconomyThe ambition to maximize profitability is one of the most

important forces driving the development of Komatsu

harvesters. Each small improvement that increases

productivity and reliability, reduces costs, or saves time

is of interest. Tangible and quantifiable examples from

today’s Komatsu harvesters include energy-efficient

engines, highly efficient hydraulics, fast heads, and

unsurpassed productivity.

ProductivityMore work in less time – a comment we often hear

from contractors who switch from competing brands to

Komatsu. There are many reasons, large and small. The

most important include extremely high-performance

operator environments, great maneuverability, effective

heads, powerful control and information systems, and

large work areas from stationary positions.

Customer SupportFast and competent service bears directly on forestry

machine performance and economy. An extensive service

network provides the Komatsu owner with a sense of

security. Well-trained technicians provide additional

assurance, as they are Komatsu experts. Another

benefit is ProSelect, our special line of accessories

and consumables. The range is based on a selection of

items that are all of the highest quality and designed for

both Komatsu and other brands of professional forest

machinery.

EnvironmentForests are an essential and fragile element of the global

ecology. Consequently, every new Komatsu product, and

all its component parts, is considered from both short-

term and long-term environmental perspectives. This

has resulted in real environmental improvements such as

highly-effective exhaust emission control and low, evenly-

distributed ground pressure in Komatsu harvesters.

Environmental considerations also permeate our broad

range of accessories and consumables, such as in our

special, rapidly biodegradable oils.

Global ExperienceKomatsu harvesters are found the world over.

Consequently, they are designed to deliver optimum

profitability regardless of conditions. The same

fundamental concept is applied to our global service and

dealer network which supports thousands of Komatsu

owners everyday.
