Thats what I was using. It took me a few minutes to get the small area done. Then again I was trying my damndest since the area really has lots of weeds and crabgrass there instead of grass and it was legit trying to pull it up.Don’t necessarily have to aerate to seed. Just get a garden weasel or even a stiff rake and rough up the soil, put seed down, and go over it lightly again to get some seed to soil contact. Covering with some peat moss or similar will help keep it moist and the birds from eating it all.

Only called it an aerator since thats what the label on the little cardboard piece hooked to it says. I did leave it attached just in case I didnt want to keep it.
