I got this to try and adapt a hitch to my lawn tractor. It didn't quite work out the way I was hoping it would, but that is no fault of this product. It's very heavy and solidly made. I'm not entirely sure what the intent was with the nut/washer combo, as the body itself is already threaded. I guess you can just add it to the end of the screw for extra footprint area.The screw is a fixed L shape, and the handle does not flip over so you will need enough room to rotate it in order to tighten it down.This review was for "Clamp On Trailer Hitch, 2" Ball Tractor Mount Receiver, Tractor Bucket Trailer Hitch Compatible with Deere Bobcat Tractor Bucket
