how lawn mower blades start getting dull after only cutting grass.

Question

Say you’re a lawn mowing professional or just your regular average ol homeowner, but you’re extremely careful and never hit rocks or damage the blade in any way. The mower blades still get dull, with only blades of grass and grass is not a hard substance. How does something soft like grass, dull a lawn mower blade?

Answer 1

Along with dulling from grass alone, I imagine the blade spinning agitates sand/gravel too (I “leaf blow” trails in my woods with the deck raised and I actually see an occasional spark from this when it’s getting dark).Throw in some acorns and there you have it
