Well i've never seen one of these before!

I don't see the value in these at all. They're slow working, inefficient handling/transport, instead of one big log lying on ground you have lots of little ones... All mixed in with crap and lots of sawdust.

 

And I bet they're not cheap plus need an expensive base unit too.

 

If you were processing at roadside in forest and delivering direct to customer then they're marginally more efficient, load would still be full of crap and sawdust though.

I still like the Hahn one on the Bobcat .
