Trouble restarting Ferguson to-35

could be that the starter is in need of being rebuilt and not wanting to work when its hot from the tractor being run. and after a couple hours of sitting its cooled down enough to crank normally. but first thing grab a volt meter and check battery voltage with the engine running to make sure that the charging system is working properly you should have 13.5v - 14.4v with the engine running that is if its been converted to a 12 volt system already

I'm not sure what gauge the cables are. I think they're the same size as a standard auto battery cable.

ok that right there could be the problem you need to use the 0 gauge cables with a 6 volt system otherwise they cant provide enough amperage to the starter. i still would suggest checking the charging system voltage with a multi meter you will want to see somewhere around 7 - 8 volts at the battery with the engine running if not try repolarizing the generator but you may have a bad regulator/cutout switch. start with basics first by gwtting the proper cables, cleaning all connections and making sure that charging voltage is good
