kmehums check the manual [document|2348] and parts list page 33 and more. There seems to only be the seat switch, PTO switch and ignition switch as well as the switch interlock. There should be one more on the clutch/brake . Checking the schematic it looks like even if the other switches were bad, they still go through the seat switch. So anything that that grounds the M terminal of the key switch kills spark. Follow the wires to determine position and make sure that is okay as well.
