What has six legs, room for a man on its back and an insatiable appetite for trees? No, it’s not a mutant beaver, it’s a Timberjack Walking Forest Machine. Designed and built by a Finnish subsidiary of John Deere, this baby will walk where wheels won’t go, then size up, cut down, and strip to lumber a tree while maintaining a dialogue with the lumberyard’s database about exactly what dimensions are required by the current customer. Low impact forest management sure seems like a good idea, although the image of an army of giant insect-like walking sawmills is a little creepy. Let’s just make sure they can’t reproduce.
