New blades are on. I hope i installed them the correct side facing down. Heres how I have them. It cuts great now but I think there's a problem. Every few seconds I can here metal hitting metal. Only when the blades are on. Like Im hitting rocks with the blades but Im not. Any suggestions?
Pull the deck off and have a look for shinny spots, that is where the blades are hitting.
Could be hitting each other or the deck or both.
Grab the ends of each blade and try to rock them see saw style.
If you can then the spindle bearings have gone.
Running with a bent blade will very often wreck a bearing .
back in the old days when mowers were a reasonable price spindles had tapered rollers like they should.
Now days nearly all have deep grove balls which is a poor substitute.
