That setup's been around for a LONG time.
Basically a "Plantation Tree" Harvester, oriented towards pulp and paper.

There's smaller versions that mount on a big skid steer.

The haulers self load,...big Hiab grapple right on the tractor.

We're a long way from spar logging in the old growth,...I'm damned glad I saw that end of logging, before it disappeared.
