Igintion wiring is wrong. Somehow, you have bypassed your switch. With the key off, try to start your tractor. If it won't start, loosen the belt so that the generator won't turn, start the tractor and then see if the key will turn it off.
Either way, your wiring is not correct. You need to trace it out.
