Has anyone had any issues with PTO disengaging? Last Saturday when cutting I thought I smelled a burning smell when I turned back upwind. Then it went away and about 15 minutes later my pto disengaged and of course the blades stopped. Looked everything over as far as the wiring going back to clutch. Pulled relays out and blew the grass out.Started mower back up turned on the pto and nothing. Started back to the trailer and they kicked on. Went back and mowed a few passes and they cut out. Seems like the switch itself is good.I hop off the mower engage the pto and mower stops which is what it is suppose to do. Thinking maybe the clutch but hoping i'm wrong. Help please!!
