So while you're out measuring, with just the drawbar on the rear of the tractor, no rear cultivator gang, how tall could front rail on a trailer be for the tractor to back over the rail until the rail hit the rear tires?
I'm working on trailer weight distribution. If I try to haul a G on an 8 foot trailer bed, it's sort of like putting 5 pounds into a 2 pound box - a 116" long tractor on a 96" long trailer bed! Back of rear tires to front of front tires must be about 99" - just 3" longer than the trailer bed! Not much wiggle room!
