Mid Iowa Antique Power Show in General Chat Posted 1 hour ago 18 minutes ago, nepoweshiekfarmalls said: I was finally able to set up this photo this morning. Bob's 826 diesel hydro gold demo serial number 11,756 and my 826 diesel hydro serial number 11,856. Special that we could reunite these 2 tractors that started life at the same time in Rock Island. Aaron, what do you figure being a 100 apart, a day or 2 apart on the assembly line? Good picture!!
