My Simplicity mower has started blowing the 20 amp fuse when my PTO is engaged. After reading many posts regarding this common problem to so many, I purchased and installed a new PTO clutch (expensive..$260), also a new PTO switch and inspected most of my wiring harness as best I could, with no worn insulation discovered. After my installation of the new PTO clutch and switch, the 20 amp fuse lasted for app. 50 feet of mowing from cold start then blew. I replaced 20 amp fuse, disconnected the PTO electrical connection at the clutch, started the mower and engaged the new PTO switch and the fuse did not ever blow, which might indicate that the wiring insulation and new switch is good but the new PTO clutch might be bad? I can't imagine that the new clutch is no good or needs an air gap adjustment already being a new OEM Briggs Stratton product, nor the new PTO switch is bad. This problem appears to be so common to so many people regardless of mower brand and model, that it seems these manufacturers cannot remedy such a common DESIGN problem to the masses! WTF? I thought about trying a 25 amp fuse but did not want to risk 'frying' my new $260 PTO clutch...Help please!! This is BS as it is such a common problem to so many!
