I've got the rck60p-33 deck on the above mower. Having an issue with one of the blades loosening up after an hour or so of cutting. I am pretty good about blowing of the deck after each cut and greasing the spindles as needed. I'm thinking this is a sign of the spindle bearings going bad. Anyone have any suggestions? Thanks,

I would get new washers (all for one spindle) and install them correctly oriented on the blade you have trouble with. Use a torque wrench to make sure the bolt is at the correct tension.

If you have aftermarket blade(s) you need to be sure it is as thick as the OEM blade(s). The bolt may be bottomed out in the treaded hole and not really tightening the blade properly if it is too thin.

But yes it could be vibration causing it to loosen.
