On mine that only happens when the mower blades/PTO is engaged.But at least now I can lean off the seat when needed without the engine dying.
But my machine is circa 1987.
UHG. I hate electrical stuff....I stink at it.According to a troubleshooting article I read, there is likely a short or improper ground somewhere in the wiring harness sending a false signal to the safety interlock system. That should be great fun trying to find it.
Do you have a technical manual?
