Hi. First off, stop throwing money away replacing perfectly good parts. Next step: apply parking brake and put a voltmeter on the connection to the starter terminal and turn the key to the start position. What is the voltage reading? Given that your solenoid is engaging to send power to the starter, there are no issues with any of the parts you have replaced. Your safety switches, ignition switch, PTO switch are all working as they should. The issue is either low voltage going to the starter or a bad starter. You must have a voltmeter to diagnose the issue(s). The most puzzling issue here is why did the engine suddenly stop running? There is a fuel shutoff solenoid on the carburetor, listen closely while turning the key from the off to on position repeatedly and listen for a clicking at the said solenoid. does it click?
Yes, the solenoid clicks. I can feel it engage when I put my hand on it. The mower starts when I jump/bypass the solenoid.
Same question I have. It's like I got off the seat while it was running. Could the seat safety switch be bad? How can I test it or bypass it?The most puzzling issue here is why did the engine suddenly stop running?
