My neighbor has a John Deere 42 inch mower with a Kohler Courage motor that was made for SCOTTS many years ago.The mower looks in generally good condition as far as I can tell, but he has a problem keeping it running. The problem is that it starts and runs fine for 10 - 15 minutes and then suddenly stops. He waits a couple of hours or overnight and it will start again. Without getting into it to deep I suggested the coil is breaking down. Does anyone have any other suggestions. Everyone have a beautiful fall day while picking up leaves on your JD mower.
