Im sure your right about the tires Alvy, the one manual covers several models so I prob read it wrong. I wouldnt bother swapping them but it would have been a good selling feature. I'd rather have a fel anyway, I had a big International a few years ago but it was too big for what I need, and it was diesel so that meant keeping another fuel source handy, I sold it and started looking for an old Cockshutt with a fel so I can also do some antique pulling for fun, I found the tractor I just need some time to work on it
