Im looking at some cheaper aerator options. I only have a couple places that would even be interested, but I want to be able to add this to my list of services. So I really don't want to spend a grand on this. So i am really looking hard at this one http://www.countryzeroturn.com/lawnaerators.htm I called and they said it pulls 3/4 x 2-3inch plugs depending on the soil conditions. I know I would have to go over it 3 times to get the amount of holes I need. http://www.zrator.com/home.html This would be the one I would prefer, but its $2100 plus shipping and I would still have to go over it twice. I would like to get some thoughts on the first one.
