Hi, this is John, now we are going to be talking about starting this riding lawnmower. This happens to be an older Craftsman mower; it still has the ignition key, a choke, and a clutch. The first thing that you need to do is make sure that you have the transmission in neutral. Next take your left foot and press the clutch with your key in the ignition turn it to on. If you need to stop the engine all that you have to do is turn the key to the left much as you would an ignition on a car.
