I have been wanting to get a good pull behind aerator for some time. Happened to be at Home Depot yesterday and just checked on rental rate for a Blue Bird TA-10 (36") aerator. The guy mentioned that it was for sale also. They were selling it for $343.20. It had maybe 4 or 5 bent or broken tines. Went back today and bought it and they lowered the price to $303 and ordered a set of 16 tines for me (they bought them). The aerator has the normal scrapes and battle marks, but looks really good. It also included six of the water jugs. I figured it'll pay for itself after 2 or 3 aeration jobs.
