Greetings and good evening to all in the land of Bitog, the great and powerful. So . . . . I have been "elected" property chairman at my Church. Went over this afternoon to cut the grass with our John Deere lawn tractor. I am happily cutting away under the Florida sun when the blades stop turning. It has an electric clutch and I pulled and pushed the knob repeatedly with no luck. The motor runs fine. The transmission works well. The blades simply will not engage. They are not stuck or jammed in anyway. What could be wrong. Could it be the switch? (The little yellow knob on the dash that engages the electric clutch). Could it be the clutch itself, and if so, aside from replacing it, what might it be in the clutch that I could repair? Is there a fuse somewhere along the way that might have burned out? If so, where does this fuse live? Said mower is a John Deere LX 188 FD501 with a water cooled Kawasaki Motor, 48 inch deck. In a word - HELP!!!
