Made if from the log puller I made a few years ago. Just added 2X4 for 2" ball. 4X4 at bottom has a 2" hole made with a 2" hole saw, 2" deep, chipped out the hole so it fits over the ball on ATV. This way the weight is still on the ball, not much on the rack. Top 4X4 has a holding bracket so it don't bounce off the ball when the suspension move up. Not for fast speed & it does lock up the rear suspension, but at slow speeds, no prob. 4'" wide inside, 7" outside. Bracket to hold it at the top to the rack. Slide the aluminum angle over the rack & ball, slid in the piece of plywood. put in the bolts, I go hand tight. Good to go. just cut a piece of a 2X6 down to 4" wide, screwed & braced it a little higher than the log splitter tongue , just have to lift it an inch or so to go on the ball, I leave it mounted to the ATV & split wood. The tongue jack on the splitter is a finger pinching "mo-fu'r". It fold up easy now, out of the way, no pinched finger or fighting to let it down to the ball on the ATV.
