    What about string trimmer line? I was doing an embankment the other day with my trimmer and i thought, why dont grass get brown tips from trimmer line. I mean trimmer line has to be duller than a dull blade is. I know this is not one of lifes great questions, but anyone know why this phenomona exists?

    I thought of that the other day while I was string trimming an area that I had mowed last time with a dull 21" trim mower. Maybe it is string speed vs blade speed?

    Actually, string trimming DOES give the turf brown tips. Just have to look and pay close attention...it's there.

    I think the whole thing is exagerated by the guy who cant figure out whats wrong with the lawn, and needs a scapegoat. Acutally, I know this to be true.

    its not like there are studies on this... *sarcasism*

    dull blades _and_ string trimming will leave yellow tips on the grass, when you look at an entire lawn of yellow tips it greatly changes its appearance.

    I have cut some pretty big areas with a string trimmer, and havent really noticed any browning as long as you keep the cut height right. My helper likes to cut too short, and that tends to brown it out alot more significantly than the cutting method. We also use Echo Crossfire .095 string, I think that helps with a nice cutting edge.
