I made one, and posted a topic on the same thing a bit back.
I need to go get the pictures of the thing. I will speak to the boss about using the camera.
I welded mine up from some extra heavy fence pipe I had laying about. What was different with mine was I support it with 2 chains. This holds everything at the right height and attitude to rehook. I do not have the Pat's quite yet, but let my wife start cussing to hook up the box blade again and I bet there is a set in the mail! And the stand we have should work beautifully with pats system.
Let me work on getting some pictures, I find the one I made very nice.
One other point though, is that we are all working with a different set of restrictions. Some do not weld, some are working with less money, some are working on concrete, and the particular thing that usually makes my stuff different from what I see here is that my wife is a landscaper and we are often working on others property. Therefore, my stand is light enough for one person to throw on the trailer, the box blade goes on the front of the trailer and the rake, and the PHD goes on the tractor then on the trailer, and away she goes. Also, my wife does 90% of the work, so I try to make it suitable for her use even when she does not realize it.
I will try and get some pictures tomorrow. Will ask about the camera tonight.
