Generally equipped with harvesting heads which sever and bunch, but not limb and bunk, these machines generally use grapple skidders and clam-bunks to forwward in the timber. There are many styles of Feller Bunchers, a few are shown below:

1) A Timberjack 608B accumulating several trees to lay down in one pile.

2) A fixed harvester head typically found on feller-bunchers. These heads usually have a circular saw for severing, which runs continuously-and is called a "hot saw", or a heavy-duty chain saw for severing.

3) A Timbco 445 B working in snow.
