I saw this machine in action on a TV show sometime ago - MegaMachines or something similar.
It looked like it could crawl up a 75 percent slope like nothing, suspect it's capable of going more places than most operators would feel comfortable taking it.
Would really like to have one here, looks like it would be just the ticket for crawling down mountain rivers, clearing all the crap out of them. With the floods we've had over the past year or so, we're still dragging out the snags.
