Abstract
A harvester that includes a harvester aggregate for felling, trimming and preparing tree trunks, a first measuring device provided in connection with the harvester aggregate for measuring of at least one dimension of a tree trunk. The harvester includes a second measuring device for measuring a feature of the first measuring device, whereby the feature is an attribute reflecting the capability of the first measuring device to measure the dimension correctly, and a control unit configured to make a comparison between an actual value of the measured feature and a target value of the feature, whereby the target value is indicative of a state of the first measuring device, where its measurement of the dimension is considered to be correct.
