And, naturally,An optimizedcombination ofstrength andflexibility for highproductivity andprofitability.The uniqueboom positionbeside the caboptimizes visibilityand minimizesneck and backdiscomfort.

941.1increased computing power ultimatelymeans optimized productivity and timbervalue.MaxiXplorer is part of the 941.1’sextremely high-performance workenvironment. The cab includes, full-circleslewing with standing room that is themost spacious on the market. And it goeswithout saying that comfort and visibilityare on a par, enabling you to maintainmaximum productivity even when workinglong days and shifts.Much of the 941’s muscle comes fromits powerful turbo-diesel engine. Maximumtorque is reached at a low engine speed,guaranteeing high-level performance fromstart to finish. The effective fuel injectionsystem ensures immediate engineresponse when you increase the workload.All this engine power is combined withremarkably low fuel consumption.Strength and flexibility also characterizethe 941.1’s boom, which, despite itshuge size, is surprisingly quick and easyto maneuver. The same is true of theharvesting head, which is extremelypowerful yet surprisingly quick and easyto meneuver. The overall sturdy designmakes the Komatsu 941 impressivelyreliable and easy to service. The end resultis a superbly hardened, productive, andsmart profit-making machine. Whetheryou’re an operator, or an owner, choosingthe Komatsu 941.1 will help you harvestmore profitability from thick forests.Cab and boom levelingand stabilizercoupling for superiorstability and groundcontact.The largest cabon the market,providingoptimum visibility,comfort, andergonomics.

941.1Why choose a komaTsu harvesTer?High productivity, low operating costs, innovative technology, superb operator environment – these arejust some of the features that make Komatsu forestry machines some of the best in the world. Behind allthis 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 environmentis critical to an operators ability to maximize productionwithout fatigue and is a key factor for success. This is animportant reference point used in developing the uniqueegronomic designs of Komatsu harvesters. Automaticleveling cabs, side mounted booms and large operatorcompartments work together to keep the harvesting headcentered in the operators field of vision.EconomyThe ambition to maximize profitability is one of the mostimportant forces driving the development of Komatsuharvesters. Each small improvement that increasesproductivity and reliability, reduces costs, or saves timeis of interest. Tangible and quantifiable examples fromtoday’s Komatsu harvesters include energy-efficientengines, highly efficient hydraulics, fast heads, andunsurpassed productivity.ProductivityMore work in less time – a comment we often hearfrom contractors who switch from competing brands toKomatsu. There are many reasons, large and small. Themost important include extremely high-performanceoperator environments, great maneuverability, effectiveheads, powerful control and information systems, andlarge work areas from stationary positions.Customer SupportFast and competent service bears directly on forestrymachine performance and economy An extensive servicenetwork provides the Komatsu owner with a sense ofsecurity. Well-trained technicians provide additionalassurance, as they are Komatsu experts. Anotherbenefit is ProSelect, our special line of accessoriesand consumables. The range is based on a selection ofitems that are all of the highest quality and designed forboth Komatsu and other brands of professional forestmachinery.EnvironmentForests are an essential and fragile element of the globalecology. Consequently, every new Komatsu product, andall its component parts, is considered from both shorttermand long-term environmental perspectives. Thishas resulted in real environmental improvements such ashighly-effective exhaust emission control and low, evenlydistributedground pressure in Komatsu harvesters.Environmental considerations also permeate our broadrange of accessories and consumables, such as in ourspecial, rapidly biodegradable oils.Global ExperienceKomatsu harvesters are found the world over.Consequently, they are designed to deliver optimumprofitability regardless of conditions. The samefundamental concept is applied to our global service anddealer network that provides support to thousands ofKomatsu owners on a daily basis.Komatsu Forest ABwww.komatsuforest.comk941_1_b_gb_110101 • TR Reklambyrå / Ågrenshuset
