Yup, that’s exactly what it looks like when sand & dirt start eating at the blade. Raising the deck a 1/2”-3/4” will cure most, if not all of that. The wings are necessary. If you grind the wings off, it will not produce lift or a satisfactory cut.
I know, I tried... 😐
Just buy new blades, raise the deck and you’ll be happy.
p.s.
I cut 6 acres.
