I live in Oklahoma and have U3 Bermuda. I have these rings on my lawn

and the rings are still there. Any ideas???? My blade is sharp. My
wheels are set even.


Just a guess.. cutting deck's not level.
Yes. It took me awhile to figure that the front "link" that holds up
the deck had broken. Although the mower is 15+ years old, Sears was
able to supply a replacement, but it wasn't an exact replacement and I
had to drill out two holes.
