:frown:I have a scag turf tiger. After I mow awhile, Pto won't engage if I turn it off, sometimes it quits on its own after mowing awhile. I replace the switch first, then put in new battery, all connectors seem fine. I air gapped the clutch. It also melts the plastic on the fuse or sometimes blows the fuse. It has 450 hrs, non commercial. At this point I'm thinking I have to replace the clutch? Is tis normal for no more hrs than this?
