Plustech Oy Timberjack Walking Harvester

I first saw this a few months back. There are a fair few mentions of this thing across the internet, but most of them say roughly the same thing. The harvester is apparently a prototype developed by Plustech Oy, a Finnish subsidary of John Deere. However, I don't think Plustech Oy exists these days. They have no online presence at all, although I did find their (dead and gone) old site,, through the Internet Archive Wayback Machine. This is what they had to say about their harvester:

The walking forest machine is Plustech's best-known innovation. The goal of product development was a machine that caused minimum impact to the terrain.

The walking machine adapts automatically to the forest floor. Moving on six articulated legs, the harvester advances forward and backward, sideways and diagonally. It can also turn in place and step over obstacles. Depending on the irregularity of the terrain, the operator can adjust both the ground clearance of the machine and the height of each step.

The machine's nerve center is an intelligent computer system that controls all walking functions - including the direction of movement, the travelling speed, the step height and gait, and the ground clearance. The harvester head is controlled by the Timberjack 3000 measuring and control system. To further optimize machine operation, Timberjack's Total Machine Control system (TMC) regulates the functions of the machine's loader and engine. All control systems are designed for ease of use. The operator-friendly controls are incorporated in a single joystick.
