Not sure if this has been posted but just saw this and figured I'd post it up. http://www.turbosaw.com/tractor.php Click the video tab.
I like the 4 sided, bolt on carbide cutting teeth. Great idea. 4 shots at cutting off those "rocks" loon ...
Bet you could wake up the neighbors whackin away with that! Our neighbor next to the old farm has been a friend of the family since long before I was born. Every year he'd get on his huge old JD tractor with a monster bush hog on the back... and he'd start dropping the hay/shrubs/sticks in the field around his pond. I'd always stop what I was doing when I heard him get closer to us, below the pond. And, I'd wait for it... Kaboom! ... a canon shot! There it was, every time. He'd hit the same rock so hard he'd come right off the seat! He told me a couple years ago (he still cuts the hay) he doesn't really look forward to that side of the pond. Said it was kind of un-nerving when he hit those... ... ya think!
You guys think that's cool? Check out the skid-steer mounted units. Makes a polesaw look stone-age stupid. They even make a feller-buncher attachment. I like the Turbo saw for small trees but for stuff under 2" or so, a heavy duty brush hog is much faster, albeit it doesn't cut as low.
