Don't have anymore info on the grapple. My tractor is pretty heavy. I think it is around 11,500 lbs. (or a litttle more) all set up (loader w/grapple, loaded tires, chains front & rear, front suitcase weights, winch and other paraphernalia. The gapple is 72 inches wide. I'm pretty sure there is a 66 inch version.
