While you're at it, have the rod ends checked for size & out of round & look carefully at the main bearings also. Cam bearings might also be suspect. If you've got the engine that far apart, you might as well pull the cam and have the machine shop take a good look at it, too.

Bearings spin from a lack of lubrication which causes the bearing shell to seize to the crank. I've seen a couple instances where the bearing seized hard enough to the crank to spin the shell in the rod end - one was an old air cooled VW engine that had been run out of oil. If it seized that tight, good chance the crank is toast, as it'll probably be gouged too deep to be turned.

Remember the science experiment in grade school where you sprinkled iron powder on a sheet of paper with a magnet underneath, to see the pattern of the magentic field. Magnaflux is just a more sophisticated version. The magnetic field will separate around discontinuities in the metal, such as a crack, which will show up as a distortion in the pattern of the test media. Finds cracks too small to see or feel.

Depending on what your goal for the tractor is, you might scrounge around & find a parts tractor with a useable crank & rods. If you're really lucky, you might find one that has usable pistons & sleeves as well. Paying for the machining, new rings & bearings, & a gasket set is a lot cheaper than all new parts.

Good luck - I hate it when things like that happen.
