That's what I thought too, sounds like a relief valve isn't working. Either that or your grapple is designed for a way lower working pressure. JP I was looking at that exact stump/root grapple on Ebay. It looks like just the ticket for stump removal, have you done any yet? I was thinking it would be great for clearing cause you could cut down the trees, buck and limb them, pile everything up, and then dig up and pile the stumps too. I'll be waiting for your complete performance evaluation
. I have lots of stumps to get rid of, I'd really like to build something along those lines.
