Another issue was that the Swedes early decided that the brush should be left on site. To act as fertilizer and to keep the grass down. This was before bioenergy from the forest was invented. I remember systems with feller-bunchers and stroke delimbers being used on site, and the delimbed stems were skidded to a landing where they were cut in lengths by a stationary cutting device. This was in the 70´s. In some cases full tree lengths were transported to larger bucking facilities to be cut and sorted before they went to the mills.
