Komatsu 825TX Tracking frame

Agile and productive in tight stands

Our thinning machines navigate narrow stands smoothly while delivering consistently high production. TX machines can be equipped with an innovative tracking frame that allows the rear wheel tracks to almost completely follow the front, with a deviation of less than 200 mm.
Komatsu 825TX Thinning gate and bunks

A load space adapted for thinning

With a load space specially designed for thinning, every detail is customised to give the best results in tight spaces. Both the gate and the stakes tilt inwards to reduce the risk of hitting remaining trees when the machine moves sideways on uneven terrain.

The gate is manually movable as standard but for extra flexibility a hydraulically movable gate is available as an option. To maintain the agile design, the gate and the first bunk are mounted together.

Good visibility makes the job easier

Good visibility is an important prerequisite for efficient and gentle work in dense thinnings. In a Komatsu forwarder, you always have excellent visibility in all directions - even down over the wheels.

The gate is cleverly designed to provide good visibility through the ribs and is also painted with a matt colour to avoid disturbing reflections.
Komatsu grapple

Handle timber like a pro

Komatsu grapples are designed to deliver high productivity in tough environments. With a large opening and good retraction properties, the grapples make it easy to gather, straighten and grip timber quickly and efficiently.

The 11 different models, including specialised variants for bioenergy and heavy-duty applications, ensure there is a grapple for every need. Their robust design and high durability make them a reliable tool, helping you to work more efficiently and profitably.

Flex Bunk - Complete flexibility

Flex Bunk is our flexible bunk system that can be customised to meet your specific needs. The standard version includes fixed stakes and a standard bunk width, but with several options available to allow you to easily tailor your load space.

Hydraulically adjustable stakes provide faster crane operations and improved fuel economy. Using the widening kit, the width of the load space can be easily adjusted using the crane as required*.

Comfort Ride 2021

Komatsu Comfort Ride

A forwarder operator spends many hours a day in the cab, making a pleasant and comfortable work environment extremely important. Komatsu Comfort Ride efficiently dampens jolts and vibrations, ensuring an ergonomic work environment. This in turn contributes to higher productivity and better profitability.

The new generation of Komatsu Comfort Ride comes with comfort-enhancing features like adjustable sideways firmness and automatic side levelling at standstill and at low speed. The elevated unloading mode now also works at low speed, to make it smoother to reposition the forwarder at the landing. Great news for all forwarder operators!

Komatsu Smart Crane

Smart Crane

Since such a large share of a forwarder operator's working day involves crane operation, increased efficiency offers great potential. Smart Crane provides the operator with advantages such as simpler crane operation, less physical strain and higher productivity. Advantages that benefit both profitability and the operator's wellbeing. Everything to make it as easy as possible for the operator to focus on what is truly important – moving timber to the roadside.

More About Smart Forestry
SpeedShift

Speed Shift

Speed Shift is a smart gearbox solution with dual hydrostatic motors, with the forwarder automatically changing up a gear as the operator increases speed. This enables the machine to accelerate continuously within the full speed range without any additional operator intervention. In this way, the engine can work at optimal engine speed most of the time, which saves fuel and provides a quiet and more comfortable work environment.

The automatic gear changes enable increased transport speed where ground conditions allow. This can include, for example, relatively flat access roads in otherwise hilly terrain that can be covered at faster speed. The longer the forwarding roads, the greater the benefit offered by Speed Shift.
