I bought the same pair of tongs from Northern. I used them once and hung them in the barn. For some reason they didn't grab the logs hard enough and hold on. I had to keep getting off the tractor and reset them. Each time they would just slip off. I tried grinding a sharper point and even setting the points with a hammer into the log. None of this worked. I gave up and went back to using a chain with a slip hook and attached the chain to the draw bar with a clevis. It's a littler more work, but it always works. I'm also able to pull multiple small trees and brush out of the woods with this method. The only draw back is the wood gets dragged through the dirt. Much harde on the chainsaw and 3pt saw buck.
