A felled and delimbed tree is cut into logs of standard sizes, a process called bucking. A logger who specialises in this job is a buck sawyer. Bucking may be done in a variety of ways depending on the logging operation. Trees that have been previously felled and moved to a landing with a log skidder are spread out for processing.
