Go look on Marvin Baumann's site I linked to up there. ^^^^
You'll see whichever one it was. He has a tractor he calls "four trans" I think it is. It ended up with more than four transmissions though because he used every single available aftermarket transmission on it. It lengthened the tractor's wheelbase. lol I think he got it to crawl at a rate of less than 12" an hour. It was stupid slow. But on the other end it was stupid fast.
