Sorry Tom, but the idea is bassacwards. If you are familiar with a breaking plow which is used to start the preparation of fallow ground for cultivation, it turns over the top several inches (usually 8" -10") of soil and pulverizes it. This aerates the soil, breaks up the sod while at the same time burying the millions of seeds on the surface too deep for most of them to germinate, but don't feel sorry for the poor seed as enough escape the burying to make new ground a challenge.
If you have access to household current one of these is easier to use and a better value:

I just bought one and it works like a charm. It only weighs 23 pounds, but don't let the weight fool you, it tears through sod and packed dirt. It won't work on rocky ground but the tool you're looking at won't either.
I lucked out. The only one left in stock was the display, but it was up off the floor where customers couldn't mess with it so it was like new. The department manager knocked the price down to $120 and then the store gave me another 10% veterans discount which brought it down to $108. Plus it does an excellent job as a power cultivator. With the wheels down it's easy to control where the tines go and how deep. Hope this helps. Claud
