This is the prototype the end result will be a little nicer. About 70 bucks will make this happen. To make this item removable so I can use the hand truck for other things when the mower isn't being stored on it I'm thinking of welding the upper and lower brackets on some 1 inch strap iron and then ubolting it to the hand truck. Also thinking of adding an angle iron support to the bottom to keep the hand truck's support shelf from bending. The bottom rod is 3/4 inch all thread rod but an unthreaded rod would be better. I used what I had. The top mounts are 3/4 inch black tees cut in half with a 3 inch nipple in them. The nipple has a 5/16 inch hole drilled in it to accept the bolt. I was able to lift it up with no problems even with my "bum" arm from a fall on the ice last month. Once upright it wheels around easily.
