The seat switch doesn't bother me to be activated when the blades are running. BUT, it should not shut the engine off when the blades are not turning, but it does. To prevent this, you have to set the brake and lock it. It's just a little bit annoying.
Our son had his own summer mowing business by the time he was 13 years old. He showed a keen interest, and I taught him the ins and outs and hazards of mowers from an early age, and by the time he was a teen he was more competent to operate a mower than the vast majority of grown men.
