The thing here in the valley and southern CA.....Heck what perma frost level do we have. So we really don't have to deal with frost heave like places where they get the crazy snow.
No Frost heave to worry about except in the mountains so to speak.
I have to deal with more root problems that aerating lawns. I would also venture that we tend to use the smaller machines and back east they are able to use the larger machines, therefore sometimes penetrating deeper than the tines
Food for thought
