It is "slip clutch" protected, also it's made to pivot up, if it's overloaded.You may be right. I hope to find out later today. Have to mow the lawn first, and then I'm going to try it. Since it's only rated for up to 40HP (I think if I remember correctly), I don't really want to run it on the larger tractor as that's 63 or 65 PTO HP, and There's a good chance I'd damage it. I guess I'll give it a shot on the smaller SCUT, and then make my decision. Since a lot of the stumps on my property are pretty old, I'm hoping that the better part of them are already rotten and won't be an issue grinding.
I have mine on a 45 PTO hp gear drive tractor with creep tranny.
