A feller buncher is a large logging machine with an attachment that cuts trees in place. It consists of a standard heavy equipment base with a tree-grabbing device furnished with a circular saw or a shear - a pinching device designed to cut small trees off at the base. The machine then places the cut tree on a stack suitable for a skidder or forwarder, or other means of transport (yarding) for further processing (e.g., delimbing, bucking, loading, or chipping).

In cut-to-length logging a harvester performs the tasks of a feller buncher additionally doing the delimbing and bucking of the trees as well. Cut-to-length logging (CTL) is a system for mechanized forestry harvesting where trees are delimbed and cut to length directly at the stump area. ...

The fellerbuncher operator approached the tree, which was approximately 104 feet in height and 3 feet in diameter with the machine and made an initial cut on the east side of the tree.
After the tree fell, the fellerbuncher operator turned to view the tree lying on the ground and observed the victim lying face down and oriented with his feet to the north and head to the south under the tree (Diagram 2).
According to the fellerbuncher operator’s manual, the proper use of the machine with the feller head saw attachment was to have both the accumulator arms and grab arms opened when approaching a tree.
