text: Components and Felling attachment Feller buncher is either tracked or wheeled and has self-levelling cabin and matches with different felling heads. For steep terrain, tracked feller buncher is being used because it provides high level of traction to the steep slope and also has high level of stability. For flat terrain, wheeled feller buncher is more efficient compared to tracked feller buncher. It is common that levelling cabins are matched with both wheeled and tracked feller buncher for steep terrain as it provides operator comfort and helps keeping the standard of tree felling production. The size and type of trees determine which type of felling heads being used.
  Types of felling heads
  Disc Saw Head – It can provide a high speed of cutting when the head is pushed against the tree. Then, the clamp arms will hold the tree when the tree is almost completed cutting. It is able to cut and gather multiple trees in the felling head. The disc saw head with good ground speed provides high production, which allows it to keep more than one skidder working continuously.
  Shear Blade Head -  It is placed against the tree and the clamp arms will hold the tree firmly. Then, the blade will activate and start cutting the tree. Same as disc saw head, it can hold multiple trees before they are placed on the ground.
  Chain Saw Head – The floppy head provides minimal control to place the trees on the ground. It might not suit to collect the cut trees or gather the cut stems in the felling head.
