LS Tractor Does not crank with key temporary solution- bump starter

This is an unedited, in-progress troubleshooting clip from an owner whose LS tractor won't crank with the key. He demonstrates a temporary workaround using a bump starter (like ones sold at Harbor Freight) connected to the solenoid wire, walks through suspected causes (starter solenoid, seat safety switch, PTO), and tests a new solenoid on camera, which turns out not to fix it. Useful mainly for owners facing the exact same no-crank symptom looking for a stopgap fix, not a polished diagnostic guide.
