I would NOT use old rod bearings with new pistons and rings. You would have a tight cylinder assembly and loose rod bearings. That can be a recipe for disaster!
You might be able to use the old mains but before you do, get some Plasi-Gauge at you local parts store (not expensive) and follow the instructions that come with it. It will tell you what the gap is between your crank main journals and main bearings. Your Tractor Repair Manual gives that gap spec. If that spec is larger than specified, then you run the risk of having low oil pressure. A thing you really don't want with new rings and rod bearings.
Another tip is to measure your rod bearing journals with a micrometer. You will probably find that they are a few thousandths undersize (again, you repair manual gives you the measurement for your rod journal diameter). They sell .002 over rod bearings on this site and other parts sites. That way you don't have to have your crank turned at a machine shop to .010 over if your rod journals are only out of spec by just a few thousandths.
The only visual inspection that is reliable is, if you can see copper showing on ANY of the bearings then they are most likely no good. All of them.
I don't have a manual for your tractor or I would have included the specs you need. If you don't have a manual I suggest you pick one up. It will be useful as long as you own your tractor and repair it yourself. There are LOTS of helpful guys on this site and if you don't want to invest in a manual, I'm sure someone will post them for you if you ask.
