The engine cut out circuit goes seat switch > parking brake switch > magneto kill terminal
Parking brake on and you can get off and dance a jig while the engine is running .
If you think about it , I have to run your engine without sitting in the seat so I can service your mower.
MTD go to the effort of taping the keys into the middle of the owners manual to encourage people to read them
Got any idea how many times I get asked to bypass the seat switch because the motor stops if the driver gets off ?
Got any idea how many times I get n their mower start it, set the parking brake , get off to check the system is working properly then look at the owner who is staring at the mower mouth open wide enough to catch birds .
