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. While many of ...
Options for cutting off the branches include chain saws, harvesters, stroke delimbers and others. Limbing can happen at the stump in log/tree length systems and cut-to-length systems or at the landing in whole-tree logging. Chainsaw limbing. When the tree is lying on the ground, branches may be storing enormous potential energy through ...
