Respectfully, I have to disagree. I've dethatched lawns that have *never*
been dethatched previously (40 years plus), and while enormous piles of

your tines are set to dig too low? Anyway, that's been my experience.

There maybe no grass above the dirt true, but the rhizomes ( if that
varity has them ) will still be left there. They will return with a little
time. When thatching to remove weeds and thatch you don't need to scalp
the lawn all too much. If your trying to change the grass varity, then
spraying is best. These are my experiences with thatching here in the Pnw
at least.
