Two Sensation Mowers I own... someday soon projects

Hi all,
I'm new to this site today. I've provided pictures of two mowers that both run well (one I've had since I was a teen mowing lawns for $$ almost 50 years ago). I found the site while surfing the net to get a lead on the bearings I need to repair some wobbly wheels and to get new catchers or repair the ones I have.
Any and all advice is welcome. Great site!
