Hello, thought I'd ask for opinions on the sudden clutch issue. Tractor is a mid 90's, Mahindra 575 DI. The clutch stopped working. Push the pedal in, no resistance and no pedal return minus the large pedal return spring that pulls pedal up. Removed bottom clutch cover plate (pic attached). Seems the pressure plate isn't returning. Picture shows the three fingers far away from throwout bearing surface. Also, second pic shows broken bolt head w/ lock washer that was on cover plate. I have reason to believe the bolt is from somewhere in the clutch assembly and possibly related to the problem. Cannot see or feel any missing fasteners yet. Rotating engine w/ help tonight to get better looks. any suggestions are appreciated. Hopefully this fix won't require splitting this tractor. Thanks.
