Is it possible to just throw a bunch of grass seed onto an existing
lawn, one that is not worth starting again from scratch, but that
could use thickening up?

Would I have to throw some soil down on top? I need to be able to
continue cutting it every week. I have around 1/2 acre to do.

Just tossing the seed does little from my experience. You have to scratch
the surface a bit for best results. Go to the Scott's web site.
