Your picture is very helpful. I do not have a welder, or anyone I know who has one. So, I went to Tractor Supply Co. and asked them for a bolt-on solution. They sold me something like one of your hooks, only a little bigger, with two 5/8 Bolts to hold it on. I am thinking about bolting it onto roughly where you have your center hook, through that thicker metal which holds the central cylinder onto the bucket. Do you think drilling two holes there would cause any loss in structural integrity?
