Walking Tractor designed by John Deere subsidiary Plustech in Finland

This gigantic mechanical spider looking beast is better known as the Timberjack, a prototype forestry machine from John Deere.

Pitched by the company as a ‘walking forester’ the Timberjack literally stomps around forests sporting a scorpion-style tail which is tipped with both a saw and a claw.

The walking forest machine is Plustech’s best-known innovation. The goal of product development was to create a machine that has the best possible working stability and minimum impact on 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 height of each step.

The machine’s nerve centre 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 measuring and control system. To further optimize machine operation, Timberjack’s Total Machine Control system (TMC) regulates the functions of machine’s loader and engine. All control systems are designed for ease of use. The operator-friendly controls are incorporated in a single joystick.

John Deere prototype walking tractor, loggers and canal dredgers have "walking" equipment too. This is a fantastic piece of equipment that can go up and down rough mountain terrain in snow and mud. It is a great practical walking machine.
