I had the 24v solenoid welded closed on my '67 4020, I had to do the same dance to tear off a battery cable, NOT fun. Makes me think I need a shutoff switch

A master switch is a good idea, I have also burnt bad battery post connections on the batteries of those 24v systems when I was younger

That is a common problem with the John Deere cabs rubbing the battery cables

Hi. Please help. I took the battery out to charge but cannot remember which cable is the positive. How can I tell? It's on the other side, is the one I'm talking about, the side OPPOSITE of where you get up into the tractor. Thanks!!

On the 30 series tractors like that could have 2 6volt batteries in series, mine has been converted to 2 12 volt parallel batteries. Either way though I think on that right side of tractor as you set in the seat, you should be able to follow one cable back that is bolted to frame of tractor that would be the negative side of battery. Then the other cable would cross over under cab would be positive.
