The Komatsu 901TX is designed from the ground up to be the world’s most productive thinning machine. It possesses an unmatched combination of performance and maneuverability making it extremely effective while minimizing its impact in the forest.

Response The new Komatsu Comfort Bogie ensures a smooth ride, superb maneuverability and improved climbing ability.

Ground clearance High ground clearance 635 mm (25”) enhances mobility and helps reduce environmental impact.

Lifting power Higher production at full reach comes from a new higher capacity crane capable of greater lift 170 kNm lbf-ft (125,386).

Ground pressure Improved front bogie design combined with 24.5” tires provide very low ground pressure.

Fuel economy Powerful 150 kW (204 hp) engine maximizes torque at low rpm. Power on demand performance with thrifty fuel economy. Komatsu design advantages help minimize service costs.

Job satisfaction Consistently high production, high reliability and great ergonomics make this machine a pleasure to own and operate.

The Komatsu Comfort Bogie delivers a smooth ride, improves mobility and maneuverability and helps to leave only a light footprint behind.

Choice of 10 m or 11 m boom reach with Komatsu head options to offer a unique balance of speed, power and low weight.

Information system The latest MaxiXplorer delivers more power and speed. Plus, it is so much more intuitive and easy to use than the previous control system.

Maximum profi tability together with minimum ground impact – this has long been considered an impossible equation in thinning. Until now. The solution is the Komatsu 901TX, a completely new thinning harvester designed to deliver the greatest benefi ts to contractors and landowners alike.

An important aspect for a thinning harvester is low machine weight, and the Komatsu 901TX is among the lightest on the market. Combined with its high ground clearance and low ground pressure, you have a very maneuverable harvester that leaves very little impact on the environment. It’s productivity gains however, will deliver a very lasting impression.

Komatsu’s swing axle coupling and the cab/boom leve-ling reduce operator fatigue and provide a stable work plat-form that maximizes reach.

The unique boom position provides a clear work view and eliminates potential neck strain issues. Just one of many Komatsu advantages.

user-friendly control system, MaxiXplorer. This intuitive system is infi nitely more powerful than its predecessor and simplifi es everything from machine control to price lists and recording data.

Also adding the effi ciency of the 901TX are the new boom design options. These are among the strongest and long reaching of any thinning harvester. Now, working with Komatsu will be faster,

more effi cient and profi table than with comparable thinning machines.

A key factor behind its combination of productivity and low environmental impact is the Komatsu bogie – delivering superb climbing ability and adding to stability and a smooth ride. Another factor is the harvester’s high performance work environment including its spaciousness, superior visibility, unique boom

placement and smooth leveling capability. The advantages allow Komatsu operators to enjoy their work fully and stay focused even on long shifts.

If you want to make the road to maximum thinning profi tability as easy as possible – choose the Komatsu 901TX!

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 fi eld of vision.

EconomyThe ambition to maximize profi tability 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 quantifi able examples from today’s Komatsu harvesters include energy-effi cient engines, highly effi cient 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 benefi t 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 profi tability regardless of conditions. The same fundamental concept is applied to our global service and dealer network that provides support to thousands of Komatsu owners on a daily basis.
