I sold dad's 88 standard diesel a couple months back. It was a real good running tractor. I didn't have it advertised, but a guy saw it that bought one of our 77's, then bought the 88D standard and a 770 diesel as well. It had 16.9-30 rear tires and 7.50-18 fronts. It would run down and pass any of our row crops like they were standing still.
