2. What is the core functionality?Combines tree felling (cutting) with bunching (gathering) into a single operation
3. How does a feller buncher cut down trees?The machine uses a high‑speed saw or a hydraulic shear to cut the tree at the base. The cutting head is on an articulated boom so the operator can reach trees from a distance.
4. How does it pick up and pile the trees?After the tree is cut, the grapple grabs it and lifts it onto a pile called a deck or bunch. The operator can then move the pile to another machine for transport.

Articulated Boom: A multi-jointed mechanical arm that provides extensive reach and maneuverability.
Cut-to-Length Logging: A harvesting system where trees are delimbed and bucked into specific lengths at the stump.
Skidder/Forwarder: Heavy vehicles used to transport felled trees or logs from the forest to a processing site.
