Where are all the safety switches on Craftsman lawn tractor?

kmehums check the manual 917273642.pdf 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.

There are two more one under gas tank that works off brake pedal/parking brake second is on the blade ingauge handle you have to remove gas tank for either

I have the sears LT1000 (green color). There is a safety switch under the control level that engages the mower blades. I have to lift the level and lower it to be able to start the motor sometimes. Also there are safety switches at brake pedal and of course under the seat. hope that helps someone.
