Here is a wiring schematic for your unit. If you notice the seat switch has a double contact setup, so simple testing with an Ohm meter will mean that you need to jump one side of the switch before getting accurate readings...
Lawn wizard, you are confusing two different circuits. Operator present circuit will shut down the engine, while reverse mow circuit shuts down the PTO. Assuming how they work will get you in trouble, read page 15, then follow Scrubs suggestion.

Here is a IPD for the model number you posted, but I don’t know if it is the correct one because the there were a couple of changes made depending on serial number. https://www.toro.com/en/parts/partdetails?id=43543&iid=440949&pid=486586. These transmissions are easily repaired, and here is a...
