654 New Holland baling problems

I bought this baler at an auction a while back and have done a few things to it since. Went to bale today and got about a 24" bale in it before the clutch started slipping terribly. I had the bale size set on 60" and it said it was full? I cut it off and got out to find that hay had bunched up between the "infeed teeth" and the roller on the very bottom that im assu!ing starts the roll causing it to jam. Maybe the hay was too wet? Or maybe the clutch is worn out? It has 13k bales through it. I'm at a loss of where to start
