No start issue with the PTO light on John Deere 4300.

This is a hands-on diagnostic walkthrough for a John Deere 4300 with a no-start condition and PTO light stuck on, tracing the fault to the belly PTO safety sensor buried under the seat. It shows checking the accessible sensor, locating the hidden one, bypassing it with a jumper wire to confirm the diagnosis, and a workaround for moving the tractor safely. Most useful for owners troubleshooting the identical PTO/no-start symptom.
