The invention relates to a tree harvester for felling, limbing and cross-cutting tree trunks, comprising a limbing head (15) and felling head (16) assembly which is carried by a boom system. The limbing head (15) and the felling head (16) are detachably connectable to one another and are commonly pivotal about a point (21) on the boom system in conjunction with a tree felling operation. The limbing head (15) and the felling head (16) can be moved away from one another along the boom system (10, 18) in conjunction with a tree-trunk limbing and cross-cutting operation, and also in different directions away from the location on the boom system at which they are commonly pivotal.
