The invention relates to a harvester head that comprises the frame (1) of the harvester head to be connected to the end of the hoist boom of a forest machine, a feeding device (4) for moving a tree trunk, a front blade (2) and/or upper delimbing blades (3a, 3b) before the feeding device (4), a cutting device (6) for cutting trunks after the feeding device (4), as well as a lower delimbing blade (5) between the feeding device (4) and the cutting device (6), installed on the side of the cutting device (6) in the frame (1) of the harvester head. In the harvester head according to the invention, the lower delimbing blade (5) is arranged to turn into a delimbing position around the tree trunk and into a space-saving position between the outer surface of the tree trunk and the frame (1) of the harvester head, away from the path (18) of the tree trunk. Furthermore, when in the space-saving position, the lower delimbing blade (5) is between the outer surface of the tree trunk and the frame (1) of the harvester head so that its end points in the direction of the frame (1) of the harvester head, wherein at least part of it extends above the path (18) of the tree trunk.
