Hello Brian. My name is***** will be happy to assist you. What happens when you release your brake pedal? Does your engine shut down?

no
Technician: Donald, Small Engine Technician replied 1 year ago
On your John Deere mower, your seat switch cannot be bypassed. Let's try something.

Remove the wiring connector from your seat safety switch. clean and lightly lubricate it. Firmly re-attach it to your safety switch, then give your mower another try.

last year it wouldnt start and i had to "hotwire " the seat switch. it worked fine until now.
Technician: Donald, Small Engine Technician replied 1 year ago
Thanks for letting me know. Have you double checked the wiring you used to hot wire your seat switch?

ok
Technician: Donald, Small Engine Technician replied 1 year ago
Many times, if your engine shuts down, after you attempt to engage your blades, this is an indication that your safety system is falsely assuming that you are not in your seat, or is not in a safe operators position. This is why I always like to begin by focusing on your seat safety switch, and the wiring connector, that attaches to your seat safety switch.

How many terminals does your seat safety switch have?
Ask Your Own Small Engine Question
Customer reply replied 1 year ago
4 but 2 of them are connected with a factory jumper wire
Technician: Donald, Small Engine Technician replied 1 year ago
You are correct, but the factory jumper is not a bypass wire. Take a look at your wiring connector. There is a spring loaded tab in the center of it. This tab is a mini safety switch, that is designed to shut your engine off, if you remove the connector from your seat safety switch.
Ask Your Own Small Engine Question
Technician: Donald, Small Engine Technician replied 1 year ago
This is why I suggested cleaning the connector, and re-attaching it, for troubleshooting purposes.
Ask Your Own Small Engine Question
Customer reply replied 1 year ago
ok. but the connector has been unplugged and hanging loose with my jumper wire installed and worked fine for the last year until now.
Customer reply replied 1 year ago
i have to run right now. i didnt plan on this much time right now. can this be continued?
Technician: Donald, Small Engine Technician replied 1 year ago
I believe I can explain this. The tab was likely stuck for years, and finally loosened, due to vibrations.
