I have a question regarding dethatching....
There are 3 options...

1) Using a thatch rake

You should have a lot of time and energy to do it using only a rake (or
a very small area to dethatch)

2) Using a lawnmower attachment

Lawnmower attachment? I haven't looked for or seen those, but I have
one for a lawn tractor. First time I used one, worked well enough, but
I think dedicated equipment would have worked better. It would be
easier to get it into places that the tractor couldn't go.

3) Renting a vertical mower

Could be the best option, especially if you don't already have a tractor.

Does anyone have any other advice on dethatching?

Mow short before dethatching and bag the clippings. If you're going to
overseed after, I've read that a second mowing would be useful after
dethatching (according to the Ortho Lawn book) but I skipped the second
mowing due to time constraints. However, after the rain and the growth
spurt in the rest of the lawn has grown quite a bit in the last 10 days.
I'm not supposed to mow that because of the overseeding so I'll just
have to wait till the new seed grows atleat 1.5" (once again, according
to the Ortho Lawn book). These are notes from my first and only
experience dethatching, so take it with a grain of salt.
