The invention concerns a debarking harvest harvester head with a pair of feed units (11, 12) that support, one on each side of a trunk feed track (5) with a direction of transport (Z), a first feeder roller (11a.11b) that can be rotated around a centra! axis (11a', 11b') and that is equipped with debarking cutters, grip arms (3a, 3b) on which the feed units (11, 12), are mounted such that the first feeder rollers (11a, 11b) can grip between them a tree trunk (2). For efficient feed of tree trunks, there is, in addition to the said pair of first feeder rollers (11a, 11b), at least one second feeder roller (12a, 12b), whereby the central axes (11a1, 11b') of the two first feeder rollers (11a, 11b) form a force-producing pair that can apply to the tree trunk with a lever (a1, a2), respectively, a turning torque around a central axis of pivot (CL), that the central axis (12a', 12b') of the second feeder rollers (12a, 12b) forms a counteracting force that can act with a lever (b1, b2) to support the tree trunk.
