Well I'm pretty sure the S/G is the culprit here.
Could still be the PTO but the one post has melted down on the S/G and it was smoking like crazy today when I attempted to mow.
I managed to get the front lawn done and she lost power which was due to the battery being dead! I have a charger on it now so I can nurse her back into her parking spot in the garage. Debating about picking up a used one from Chris on here or buying a rebuilt one for a little extra at this point.
I'm guessing the bearing is seizing up on this one and will probably have it rebuilt if possible locally.
Guess I shouldn't have held off mowing the lawn so long, that rear is going to be fun when I get her back together.
