My 2018 Cub Cadet shut off when I got off of the tractor as if the PTO was still engaged, even when the PTO was disengaged, and since then it has only started once when I directly jumped the starter with my car battery. Doesn't even try to turn over. I changed out the the solenoid and still nothing. Bought a new battery and nothing. Bypassed the safety switch, nothing. Not even a click when I try to start it. I’m wondering why I was able to jump start it the one time through the starter after the issue arose, but now nothing at all. Help!
