The test focuses exclusively on timber value, not on productivity or fuel consumption. Evaluated areas include positioning accuracy, measurement accuracy, cross-cut quality, and functions for value and assortment optimisation.

Strong positioning precision
A new parameter in this year’s test was the accuracy of stem and log positioning. Here, Komatsu demonstrated very strong results. Stem positioning showed an average deviation of 16 cm, the highest precision recorded in the test. Log positioning also showed high accuracy, although in that particular test Komatsu Forest was the only participating manufacturer.The results reflect Komatsu’s long-term commitment to precision within Smart Forestry, where reliable positioning data is becoming increasingly important for the future of digital forestry.High measurement accuracy in the harvesting head
Measurement accuracy is a key factor in preserving timber value. In the test, the Komatsu harvester measured diameter with 83 percent of logs within ±4 mm, placing it among the top performers. Length measurement was also at a high level, with particularly strong accuracy for saw logs.

This, in turn, provides solid conditions for consistent bucking and stable value recovery over time.

A test pointing both forward and beyond
The Timber Value Test provides the industry with an objective and comparable picture of how different solutions contribute to preserving timber value. For Komatsu Forest, the results show strong performance in several key areas, not least precision and measurement accuracy. At the same time, the test offers valuable guidance for continued development, with a focus on long-term, value-driven harvesting.
