As far as crankshafts go, I'd think sponsors would have plenty around, especially considering that to get a good keyseat the shaft should be welded over and the key cut opposite the old key, I'd be willing to bet that the cost of machine work is more than a used crankshaft, even if it needed a undersize cut. If I've got some sitting around I'd certainly think that they'd be easy to find from a sponsor.

You're right, an articulated 4wd might do better, but the trailing adapter is still going to take weight off the tractor. I think that on top of the fact it's leaving you at a disadvantage it's weight restriction might be tough to get around with the force required to pull a plow.
