Agile and low-impact thinning

When thinning in dense forests, a harvester manoeuvred with both ease and agility without impacting standing forest is a must.

Our thinning harvesters are designed to do just that. Thanks to their compact size, they can operate in confined spaces and both the cab and the crane are designed for smooth movements to reduce the risk of damaging standing forest.

Another advantage is our tried-and-tested parallel crane, which simplifies crane operation. Thanks to a combination of strength and speed, it also contributes to efficient work methods.

A good overview simplifies the work

While good visibility is always an advantage, in thinning it is especially important. Our harvester cab is designed to provide the operator with extremely good views of both the head and the treetops. Moreover, our thinning harvesters are also lower than the larger machines, enabling you to see the trees from a better angle when thinning.

In a Komatsu harvester, you sit facing the same direction as the crane, which makes thinning easier as you can see exactly where you can extend the crane. This reduces the risk of misjudging the crane's position, meaning less damage to standing forest.

Some of our harvester options

The right head for every assignment

The choice of head always begins with the conditions faced in the forest. There are all kinds of trees, each of which poses different challenges requiring specialist solutions.

Our broad offering encompasses heads specially designed for particular types of forest and suitable for everything from initial thinning to final logging of the largest trees.

For the 901, you can choose between the following heads: S82, S92, C93

By the way, did you know that the storage space in the panel behind the driver's seat can be used to cool bottles of drink? Ideal for keeping cool on hot days.

Smart Crane Harvesters

Crane operation at its easiest

For a harvester operator, an easily operated crane is important for ensuring a productive working day. With Komatsu Smart Crane, the crane – from the main boom all the way to the tip of the telescopic arm – is controlled with a single, smooth lever movement.

Thanks to the crane’s precision and responsiveness, the operator can easily steer the head where they want it, contributing to a more relaxed way of working. A relaxed operator can keep up a high and steady production during the day and still feel more refreshed at the end of the working day. Advantages that will be seen in both profitability and the operator’s well-being.

Smart Forestry Precision

Smart Forestry Precision uses the latest technology in satellite positioning to determine the machine’s position with an error margin of just a few centimetres. This paves the way for productive and smart work methods where the operator is provided with key information and support to enable informed decisions.

There are several useful functions within Precision, like the ability to create exact, digital fences to mark the borders of a work area or around protected areas. It's also easier to classify stems based on environmental considerations with the stem code visualisation tool.
