I have a JD 180. Last night was I was mowing the back and the blades just stopped... PTO was engaged. Wiggled the switch nothing.... Took the mower to the garage and sure connections were all snug. Now if I engage the blades and get off the seat, the safety switch will cut the power tohe mower, which is what it's supposed to do.
Anyone have any pointers as to what could be wrong. I bought a new PTO toggle switch as I was told at the Deere store it could be one of a few variables that could be wrong...
I'm guessing what he means is the blades don't turn on but the engine quits with the blade switch on and him off the seat. If that's the case then it sounds like your switch is working. I'm going with a bad electromagnetic clutch.
Try adjusting thre clutch first. The spec is .018" of air gap. Be sure to measure the air gap b-4 adjusting. I am just curious. You should adjust all 3 nuts at least 3 times to make sure adjusting 1 didn't change the others.
