How and where do you locate the safety switches on a Power Kraft riding mower?

There will be one for the neutral position, the blade engagement, and the seat.
The seat switch is under the seat. The blade engagement will be under the frame usually. And the neutral position switch will be on the clutch/brake assembly underneath the frame, this is also the clutch / brake safety, so it will start in gear also, if the clutch / brake is depressed.
