Welcome to TBN
Great addition to your tractor :thumbsup: You will find it extremely useful for all kinds of stuff. Logs, brush, rocks, ........ Mine is a similar bolt on grapple. I couldn't live w/o it. You have better teeth than on mine. I welded some teeth on my grapple fingers right off then later added some to the bucket edge. Helps to grip hard slippery, frozen or wet, logs like beech. The teeth are pieces of 1/2" rebar.
What type of grapple is that?
