I have that grapple and it works fine. I had a Land Pride grapple with my last tractor and only notice the top lid of the CTGR60 is not toothed like the LP. I don’t really need that for what I do, but if you like to rake backward, lid teeth would be needed I bet. Also, the LP was AR400 and the IC “AR36” per the factory tech I called. I don’t know if that is really just A36, I’m not a steel worker.
I forgot to add, I use the clamshell type for this reason. I dig the bottom teeth into the soil to rip saplings and small brush. It does a good job, as long as you’re not trying to pull large stumps or anything.
