Abstract
A tree harvester head structure is connected to a mounting structure on a mobile tree harvester by a compact coupling which provides lateral pivotal movement of the harvester head structure. An antifriction bearing and a fluid powered rotary actuator have a concentric relationship and are in substantial radial alignment, thus creating a compact design and avoiding additional side loading of the bearing. A brake prevents rotational movement of the tree harvester head structure except when the rotary actuator is operated.
