It's just a tractor.  Yes, he will probably regret it, but I've regretted almost everything I have done at some point.  Maybe everyone is just offering advice based on experience.  But it is just a tractor.

Having said that, right now we have Gramp's B's (2 of them) and 560.  We have Dad's B, 1939 H and 1939 M (it was always important to him to include the year) and 460.  That's great, we use them all a little, they don't cost us much and we have places to keep them.   But I'm not running a museum and one of these days they will go down the road.

I may have to outlive Mom and 2 brothers first ...
