That's an impressive picture, but the 'lumberjacks' that I've seen lately by our cabin in WI are two guys with a giant robot-like machine that grabs onto the tree, cuts all of the branches off, cuts it into separate sections from the top down, and stacks them for the trucks to come and pick them up.
I don't know what their rate of clear-cutting is, but they seem to clear out about a city block size in a week.
Something like:

except the ones I've seen don't walk.
So I would expect the numbers to get better going forward.
- unwind 11y agoI believe the equipment you're seeing is just ordinary forestry harvesters (https://en.wikipedia.org/wiki/Harvester_%28forestry%29 https://en.wikipedia.org/wiki/Harvester_%28forestry%29) then. They're typically wheeled or tracked. Not sure if having legs is much of an advantage, although it sure looks cool. One big thing about this kind of equipment is controlling ground pressure. I guess the feet of a legged robot can have larger surface area (and thus lower pressure) than the contact surfaces of a wheeled vehicle so that might be an advantage.
