I would also argue that the Plugr style aerator actually breaks up the soil more than a drum style machine. On some soils, I kid you not, you can see the ground roll behind the machine. Take a drum aerator over wet soil, (no sod) and it looks like a reverse of the drum-tine pattern, holes all in a row, take a Plugr over bare soil, and it looks like its been roto-tilled.
