I agree with the above. I have an aerator and used it a lot at first but for the time, fuel, money spent it does not pay. I hardly use mine at all now and will run it on cow paths after grazing in row crop fields when I pull them out. Take the money and spend it on fertility, lime, litter, get your P and K up good. All of this will promote worms and natures own aeration. I have heard they are super high now and I paid like 6500.00 for a 10 foot with the wheel kit. That was back in the 90s when I was younger, I am wiser now. haha.
