It seems as if both bearing adapters and pulley wheels may need to be replaced. Yes?
Not sure, cant see it, havent checked it.
I would assume that if there is sloppy, there is wear and no lubricant left.
Replacing them now is probably a better idea than waiting for one of the pulleys to part company with the mower.
Dont mean to come across as a smart arse, but theres only so much you can diagnose over the internet.
The cutter brake acts on the cutter pulley, which could have a slightly out-of-round mating surface with the brake. This pulley does not show worn bearing behaviour.
Take some care as the blades could still hurt you, but you should be able to spin the deck up by hand and watch the pulley.
Perhaps the pulley is a little warped and either the deck brake has lost its tension (not sure exactly what your deck has) or the deck engagement mechanisim is worn and not lifiting the deck as high as it used too. Or a combo of both. You might be able to adjust the brake for more tension.
