I would say no, you cant clamp hard enough on a sapling to get enough purchase to rip it out of the ground. You can break it in half, or mangle it, but most grapples dont pinch precisely enough.
Instead, you can get a grapple tooth in the ground and dislodge the entire tree, stump and all.
My used Kioti CK3510 came in a package with an Everything-Attachments wicked 55" grapple. Which worked fine, but I promptly listed for sale - I wanted a log-carrying style grapple instead. So I bought the MTL 54" compact tractor grapple instead, and profited $500 overall after flipping my used EA wicked 55". The EA wicked grapple was fine, but could only carry one log at a time, since it has no bottom jaws to speak of. When I am felling trees or collecting firewood poles, I need more carrying capacity.
