Aerating heavy thatch

[PokerPlayer]

I just bought a billy goat aerator. I had rented in the past and used a Ryan. Both seemed to have trouble plugging holes where it was needed most in the heavy thatch. Does anyone else have this problem? Anybody have any tips on how to correct this?

We have had good luck in heavy thatch when the ground is good and wet. Try doing a few of these yards after a good rain. Other wise you might have to dethatch first and then aerate.
Good Luck
