OK, Ill admit it.
There I was horsing another pto coupling on the tractor shaft when... the pto hood... started to... move! upwards. YUP, turns out those arent just mounting bolts at the top of that shroud, they're pivots, with bumper feet at the bottom of the it. so I figure I can:
1.plead insanity (stoopidity?) or
2. swear I read the manual, and it wasn't in there (I did and I sure didnt see it).
anyways, flinging that thing upwards against the casting sure opens up the real estate!!
