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.

Ideal for combined assignments

Our versatile machines are flexible all-rounders suitable for anyone who works with both late thinning and lighter final logging.

The agile yet robust design and 230H crane make this harvester incredibly strong even at long reaches. This particular crane is also suitable for heads with multi-tree handling.

The 26.5" wheels pass obstacles in the terrain extremely easily while also being ideal for snowy ground.

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.
