Abstract
A method and arrangement for adjusting a feed rate of a crosscut saw (), in particular, in a harvesting head of a forest machine during the crosscutting of wood () in the apparatus. A feed force (F) of the crosscut saw and/or a rotating rate (v) of a cutter chain () revolving around a guide bar () are thus controlled. The control is implemented such that first the feed rate (v) of the crosscut saw () is measured at given intervals. By adjusting thereafter the feed force of the actuator () controlling the crosscut saw and/or the rotating rate (v) of the cutter chain () and by determining the effect of the performed adjustment on the feed rate of the crosscut saw any change (δv) in the feed rate and the most advantageous adjustment measure to be performed next is concluded.
