Answer
 Hello Dick:

 Check the Model Numbers, Please. I can't Locate this Model Number in my Manuals or Online. However, Does this Mower have a Series of Relays Under the Seat on the Frame? If Yes, then Check the Relays. One of them is Bad. Most Times it is the Middle Relay. All 3 Relays are the Same. If there are No Relays on this Model, then Check the Wiring Harness for a Bad Wire From the Seat Safety Switch. From your Description the Seat Safety Isn't Working with the Other Safety Switches. Jumper the Seat Safety and See what Happens. With the Proper Model Numbers I can Locate a Breakdown/IPL and Better Assist you. Hope this Helps. I am here if you Require more Assistance. Let me know what Happens, Please. Thanks.

 Good Luck

 Respectfully

 John
