Cannon, looks like you got it now.
Cad, I think those are gauge wheels on that deck. I couldn't find a manual for it but they look just like the ones on the 3000 series tractors. It was too much money for Cub to put bearings in them so they used a brass insert that will wear out. My Kubota B7500 uses the same poor design and I replaced them a few times until I switched both over to a sealed bearing and have had no problem since.
