That is usually caused by a bad seat switch or a bad connection at the switch. It is a safety feature that will not allow the mower to drive or blades to turn if no one is on the seat.
There's a solinoid in the transmission.Suggest to check that first. Turn on interior lights. Start engine. If the lights go out when the engine stalls, you have a bad ignition switch.
Turn your blades off.
On my 2003 Chevy suburban the wiper blades don't stop when you turn off the switch sometimes, i would appreciate any help at all
when kick down the gas pedal to accelerate, the car downshift but then stalls and then engine stays rough until i turn off the engine and restart it then the engine runs normal again till the next kick down.
Clean/replace spark plug and air filter. If problem persists, open needle valve 1/8 of a turn for a slighlty richer mixture, Something else to check. Some riding mowers have a sensor switch that will not allow the blades to engage unless the clutch is depressed. The switch may be faulty. Not sure exactly where it is located, but since it is activated by the clutch pedal, I figure that is the place to start.
maybe its a sens or relay connected with ac and the engine blower
Exhaust gases from engine spin the blades which in turn drive a turbine in the inlet manifold that forces air into a engine.
Most likely it's the motor assembly. There is an internal switch that keeps the motor running until the wiper blades are in the "park" position. If the internal switch fails, the wiper will continue to run or will turn off wherever the blades are when you turn off the wipers. Either can happen when the wiper internal switch fails.
The reason the mower dies when the blades are engaged can be caused by a couple of different things. One, the spindles for the blades are frozen so the blades can't turn stopping the engine. Two, the fuel system isn't allowing sufficient fuel/air flow when the engine is put under a load.
BAD IGN SWITCH
In most cases, the engine will not fire or start if the clutch switch is bad. The key will turn in the ignition but there will be no turn-over or sound from the engine. If the engine turns over but doesn't start, there might be a problem with the fuel supply.
