Thanks for the help. I will get together the items I need, and make the change this weekend. It was strange that with the wiring configuration in the photos, it would not start with a negative ground from the battery, but started immediately with a positive ground.
The coil is also polarity sensitive. If you had it wired up backwards for negative ground the spark may have been too weak for the engine to run. That's why switching the battery around made it run.
Unless you mean the engine would not even crank over with the starter. Then it had nothing to do with polarity and everything to do with bad connections at the battery. Swapping them around was enough to clean the connections so they would work.

After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
