721D runs after key is off just replaced ignition switch

[Aanchordan]

What could be causing my 721D to keep running once turned on, if Iturn the key off it still runs. I went and got a new ignition switch today and went to turn it off and its still runs. I pulled the fuel line off to stop the engine. HELP!!!
Oh its a 1995

Sounds like the kill wire that goes to the coil and through the switch is disconnected somewhere.

I have a 721d as well and it had the same issue. To kill the motor I had to pull the linkage arm the shut off the fuel..I went to a local Kubota store and bought a new return spring and adjusted the linkage arm for the fuel solenoid. now when you shut the key off and throttle down the motor shuts off..still haven't fixed the true problem but it works. I've spoke with GH about this and have not pin pointed the true problem yet...

Yes hello, we had this same problem in our business this last year. We run two GH 325D mowers. The shut off solenoid was bad and that our machine had about 1400 hours on it. I hope you've resolved your issue.
