I can start the tractor with the Clutch pedal pushed in. However, when I release the clutch pedal the motor shuts off. I have done the following things:

1. By past the seat switch--connecting the to wires.
2. Replaced the Interlock switch attached to the clutch petal system.
3. Replaced the PTO switch.
4. Replaced the Clutch, OGURA.
5. Checked for continuity for all the wires from the switches to their destinations

I do not know what else to do. Can you help?
Please let me know, so if you cannot help I can move on.

Thank you.

Separate the two seat switch wires. Remove the jumper if that is what you did. Also be aware that some of those seat switch connectors have a self shorting clip in them that closes the two wire circuit when the seat switch is unplugged. It will look like a square between the two prongs in the connector that will move if pushed down. You want the seat switch to be an open circuit for testing that system.

You may not have bypassed seat switch. Many are NC - Normally Closed. So, mower thinks you aren't in seat. Check switch continuity w/ plunger out vs plunger in.

Triple ditto on the seat switch.
Because of all of the brain dead morons who post videos of how to bypass the switches a lot of the newer ones can not be bypassed short of cutting the wires between the plug & the switch.
It has made servicing a lot of them a real PIA

Sit on the mower & start the engine.
With your foot still on the clutch brake pedal try to engage the PTO
If it won't engage or the engine stops then the culprit is the seat switch.
