This invention concerns a feed wheel arrangement intended to be used in a timber working head for at least one of felling, trimming, bark-peeling and cutting of a tree or tree trunk, comprising a frame to which feed wheels and grip fittings are mounted either fixed or in a manner that allows them to be removed. The feed wheel arrangement comprises a feed wheel with a power transfer arrangement lowered centrally in a jacket of the feed wheel, a motor arranged at a distance from the feed wheel, and a power transfer arrangement for the transfer of rotational force from the motor to the feed wheel, for the feed of the tree or trunk through the timber working head. The invention concerns also a timber working head, a crane and a timber working machine.
