Unable to say which is best, but don't get a real heavy one, or one setup and listed as a root rake. My buddy installed one that weights about 1000 pounds on his 65hp JD. The thing is made with dozer teeth on the bottom, heavy steel with serrations on the inside (like teeth). The point is the grapple weights is about a 1/3 of what the loader can lift, so this reduces the amount it can carry. The loader is not strong enough to be able to use the teeth as a root rake, and if it is used this way, the tractors loader arms are going to get bent.
Use it just for picking up brush and fallen trees
