A feller buncher is a type of harvester used in logging. It is a motorized vehicle with an attachment that can rapidly cut and gather several trees before felling them.
A feller buncher consists of a standard heavy equipment base with a tree-grabbing device furnished with a chain-saw, 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).
There are also wheeled feller bunchers with no articulated arm. Instead this type of vehicle drives close and grabs the tree.
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.
