ABSTRACT:
A felling head for successively grabbing a number of upstanding trees, sequentially sectioning same, and capturing a number of sectioned tree sections one at a time to constitute a pack of sectioned tree sections held by the head, before it is required to unload the tree sections. The felling head has a ground-skimming horizontal knife that cuts trees, while a pair of upper grabber arms and a tree retaining lever capture that tree. The grabber arms then release the sectioned tree section, for engagement with a second upstanding tree, while the retaining lever retains the sectioned tree against the head.
