I finally got around to building my portable hay rack. It is about 7 foot long and 3 foot wide at widest point where a catch tray catches the hay. Hay loads from the top of the rack where the hay goes in. On skids for moving and mineral feeder on end. This is the best hay saver I have ever seen. Scrap tin roof keep hay dry. Cost of lumber about $125.00 When I move to new pasture for pasture rotation, I just hook it to my mule and pull it wherever I want.
