ok guys I know this subject has come up alot on here, also I did a search with no luck in one place. I just got 10 aerating accts on some of my full service customers, my question is I am looking to buy a used aerator. Which one, claussen, bluebird, ryan or snapper? Each lawn is approx.3000ft2. I can buy a used one ( any of the four brands ) for about 450.00 from a local rental yard about 4 years old. Is this a fair price and which would you choose and why? Thanks in advance for all the good info. Ramirez Landscaping Co.
