I have to redue 14,000 sq foot of lawn. It is bluegrass sod, and the owner wants to go with tall fescue.... I am trying to decide the best way to get this done, and like the idea of a rotodarian style machine like the Soil cultivatior. The grade is perfec, Sprinkler heads are in, and I am afraid the cultivator might fluff up the soil so much that it will elevate me where I don't want to be? The harley rake is an option, but I would have to do something with all that sod. I have thought about round up, mow to the ground, and aerate....slit seed to death. I want an excuse for the Dingo...that is why I brought it up. Thanks for your help.
