Riding Mower and Tractor: Dies when brake released

If the engine shuts off as you release the brake pedal, the seat switch is the likely failure. The seat switch grounds the ignition system when the brake is released and the seat switch doesn't detect a rider on the seat. Check to see if the seat switch wire harness is plugged in. An unplugged seat switch shuts off the engine as if the seat is empty. If you find the seat switch plugged in, then the seat switch could be defective or the wire harness could have a short circuit grounding the ignition system. Replace the seat switch if you find it defective.

Seat Switch

The seat switch kills the engine if the switch doesn't detect you in the seat when you release the brake. To prevent tampering, the seat switch also stops the engine if you unplug its wire harness. When the engine dies as you release the brake pedal, check the seat switch wire harness to make sure it's plugged in. Replace the seat switch if you find it plugged in but not recognizing your presence on the seat.
